PART I

Item 1. Business

Overview

We are a medical device company that specializes in the design, development and manufacturing of a patented carbon dioxide (CO₂) laser and disposable handpieces, known as the Heart Laser System, that is used to treat patients with severe angina in a surgical procedure known as transmyocardial revascularization, or TMR. In the United States, we sell our TMR products to Edwards Lifesciences LLC. Edwards has the exclusive right to market and distribute our TMR products to hospitals in the United States.

Our current business strategy involves broadening and diversifying our product portfolio beyond our current TMR offerings, by developing or acquiring new and innovative medical devices to address cardiac and vascular related markets. Recently, in pursuit of this strategy, we entered into a new agreement with Edwards to develop and manufacture a surgical cardiac ablation laser designed to treat cardiac arrhythmias.

In conjunction with signing this new development and manufacturing agreement we also modified the terms of our existing TMR distribution agreement with Edwards, which included extending the term of the agreement through at least October 17, 2017 and adjusting our domestic TMR disposable revenue sharing arrangement in exchange for a payment to us of $4.5 million (see “Growth Strategy - Edwards Transaction” for a further detailed description of this transaction).

Edwards is our largest shareholder, owning approximately 18% of our outstanding common stock as of December 31, 2003, and has a representative on our Board of Directors. Edwards is also our largest customer, accounting for approximately 89% of our total sales in 2003.

The TMR Procedure

TMR is performed by a cardiovascular surgeon, who uses a laser to create channels through the myocardium of the heart in an attempt to restore perfusion to areas of the heart not being reached by diseased or clogged arteries. This technique is used as a late or last resort for relief of symptoms of severe angina in patients with ischemic heart disease not amenable to direct coronary revascularization interventions, such as angioplasty, stenting or coronary artery bypass grafting (bypass surgery). In addition to providing new direct pathways for blood to reach the ischemic myocardium, the creation of TMR channels is also believed to promote angiogenesis, the development of new blood vessels.

The Heart Laser System

Our first generation Heart Laser, or HL1, is a high-powered laser capable of creating a TMR channel completely through a human heart wall with a single laser pulse delivered in the fraction of a second between heartbeats. In August 1998 we received approval from the FDA to market the HL1 throughout the United States. We were the first company to receive FDA approval to commercialize a product to perform TMR.

In January 2001 we received approval from the FDA to market our second generation Heart Laser, or HL2. The HL2 is less than half the weight and size of the HL1, but delivers the equivalent laser energy, wavelength and beam characteristics.

Each TMR procedure requires a sterile, single use TMR kit containing assorted TMR handpieces, drapes and other disposable items. The HL1 and HL2 lasers each require a TMR kit to be used as a complete system. The same TMR kit may be used by either the HL1 or HL2 laser. The combination of either an HL1 or an HL2 with a TMR kit is commonly known (and is referred to throughout this report) as the Heart Laser System.

We manufacture the Heart Laser Systems at our facility in Franklin, Massachusetts.

Growth Strategy

Our goal is to aggressively seek out new and existing opportunities in the cardiac and vascular related markets that possess substantial revenue growth prospects, as evidenced first and foremost by the existence of a large, unmet clinical need. We will then utilize a methodology for evaluating which opportunities best fit our overall business strategy for bringing products to market in a timely and cost efficient manner.

Some of the key factors besides market size we will evaluate in our decision making selection process are the (1) likely regulatory path (Pre-Market Notification (510k)) or Pre-Market Approval (PMA)), (2) existence of established reimbursement codes, (3) intellectual property considerations, (4) overall competitive landscape, (5) technical complexity of the proposed product or solution, (6) ability to assess early in the product development phase the likely feasibility of the overall project (as a means of applying an early risk reduction strategy), (7) likely distribution channel and (8) overall synergistic fit with our existing or desired new core competency set.

Once we select an opportunity to pursue, we will systematically evaluate the best means by which to address the unmet need. This most often will be through the acquisition, licensing or development of a unique and innovative product or technology.

During 2003 we committed ourselves to this process and we applied our methodology to a host of ideas. We concluded that our best first step in implementing our new business strategy was to leverage both our existing core competencies in the field of laser technology and our existing distribution channel with Edwards by entering a new market that is still emerging, but which is characterized by a large, unmet clinical need in terms of the treatment of a prevalent disease (atrial fibrillation). This market possesses many of the key attributes we were seeking, including existing insurance reimbursement. Our recent transaction with Edwards that closed in February 2004, and which is described in detail below, brought to us the exclusive manufacturing rights to a patented product that we believe has already substantially undergone the most costly phase of its development process. It also has FDA marketing clearance (510(k)) already in place.

We are working to finish the development of this product and hope to bring it to market within the next 12 months.

Edwards Transaction

A summary of our new agreements with Edwards follows:

Optimaze Laser System

In February 2004 we signed an agreement with Edwards to continue the ongoing product development and manufacturing of the Edwards Optimaze surgical ablation system (“Optimaze System”). The Optimaze System is a diode based laser system designed to treat cardiac arrhythmias, or heart rhythm disorders. The most common cardiac arrhythmia is atrial fibrillation, a condition that afflicts an estimated 2.2 million Americans (see “Cardiovascular Diseases and Current Therapies” for a description of atrial fibrillation and the available treatments for this disease).

Under the terms of the agreement, after completion of development and an agreed upon transition period, we have the exclusive manufacturing rights to build the Optimaze System and any other surgical products developed for the treatment (including minimally invasive treatment) of atrial fibrillation and atrial flutter. Edwards is our exclusive worldwide distributor for these surgical products and is prohibited from offering for sale any directly competitive surgical products without first offering such competitive products to us to manufacture.

The initial term of the agreement continues, subject to certain cancellation provisions, for the enforceable life of the last to expire patent within Edwards intellectual property for these products, which presently is September 9, 2020. Any inventions developed by us during the term of the agreement will be jointly owned.

Edwards is responsible for the approval, funding and conduct of all clinical studies designed to obtain data in support of a product approval or clearance as required by the FDA or other regulatory authority. The Optimaze System was cleared by the FDA through the 510(k) premarket notification process for use as a surgical instrument for coagulation of soft tissue, including cardiac tissue, in open or closed surgical procedures. Although some physicians may use the device for treatment of atrial fibrillation under the practice of medicine exception to the Federal Food, Drug, and Cosmetic Act, neither we nor Edwards are permitted to promote the device for that use.

We are responsible for the research, development and manufacturing of certain identified surgical products under this agreement and in addition we are obligated to make available up to 10% of our trailing twelve-month revenues derived from products sold under the agreement for investment in the development of additional surgical products.

We have an agreed upon sale price arrangement with Edwards for the Optimaze laser. We also have entered into a revenue sharing agreement with Edwards as it respects the Optimaze disposables. Edwards will initially retain 65% and we will receive 35% of all customer generated Optimaze disposable revenue. Our transfer price on both the Optimaze laser and Optimaze disposables will be adjusted in the future in the event of product cost increases or decreases and, in the case of Optimaze disposables, in the event of selling price increases or decreases.

Edwards has the right to terminate the agreement prior to the expiration of the initial term upon written notice to us. In the event that Edwards terminates the agreement without cause, we will obtain an exclusive, irrevocable, worldwide, perpetual license to manufacture and sell the surgical products under the agreement, subject to a 10% royalty on net sales payable to Edwards. In the event that Edwards terminates the agreement other than for cause on at least 60 days notice, then Edwards must pay us a termination fee of $2,000,000, in addition to granting us the rights to manufacture and sell the products as described in the prior sentence. Following the second anniversary of the agreement, Edwards has the right to terminate the agreement on 180 days notice without payment of the aforementioned fee.

TMR Distribution Agreement

In conjunction with signing the development and manufacturing agreement for the Optimaze System, we amended certain provisions of our TMR distribution agreement with Edwards. The initial term of the TMR agreement was extended from January 2006 to at least October 2017. In addition, we modified our existing revenue sharing on TMR disposable kits such that we now receive 36.5% of the customer generated revenue on all TMR kits, down from our previous 45% share in 2003 and 2002. Edwards made an upfront payment of $4,533,333 to us at the time of signing both these agreements. This payment is being treated as deferred revenue, which we expect to recognize as revenue in our consolidated income statement over the next seven years. All other terms of our existing TMR distribution agreement with Edwards remained the same.

Cardiovascular Disease and Current Therapies

According to the 2004 Heart and Stroke Statistical Update, or 2004 HSSU, which was published by the American Heart Association, an estimated 64.4 million Americans suffered from one or more types of cardiovascular disease in 2001, with an estimated 13.2 million suffering from coronary heart disease, 6.8 million suffering from angina pectoris (chest pain) and 2.2 million suffering from atrial fibrillation.

Cardiovascular disease is the leading cause of death in the U.S., resulting in approximately 39% (or 931,000 in 2001) of all deaths in the U.S. annually. The American Heart Association estimates that the direct and indirect costs of cardiovascular disease in the year 2004 will be approximately $368 billion.

Angina – Current Treatments

Angina is the medical term used to describe the chest pain or discomfort that an individual can experience when the heart does not receive an adequate supply of oxygen rich blood. This can occur when the arteries supplying blood flow to the heart muscle become partially blocked or narrowed by the accumulation of fatty deposits known as plaque. This condition where plaque progressively builds up in the interior walls of the arteries, resulting in reduced blood flow to the myocardium, ischemia and angina, is known as coronary atherosclerosis. Atherosclerosis is the principal form of cardiovascular disease and the primary cause of heart attacks. Traditional treatment of atherosclerosis as a means to improve blood flow to the heart includes drug therapy, angioplasty, stenting and bypass surgery.

Drug therapy alleviates some of the symptoms of atherosclerosis but is often ineffective in serious cases. Angioplasty is a less invasive treatment for arteriosclerosis than bypass surgery. The most common form of angioplasty involves inserting a catheter with a balloon at the tip into a diseased artery. By inflating the balloon at the site of blockage, the arterial plaque can be pressed against the arterial walls and reshaped, resulting in increased blood flow and decreased angina symptoms. According to the 2004 HSSU, an estimated 571,000 angioplasty procedures were performed on 559,000 patients in the U.S. in 2001.

Metallic stents were developed to help prevent the closures that sometimes occur after angioplasty and to help reduce restenosis. These stents are inserted into the artery after balloon angioplasty to hold the expanded plaque in place. Because it is less traumatic and less costly, balloon angioplasty is preferred over bypass surgery when the blockages are not complicated and involve few coronary arteries. While offering certain benefits compared to bypass surgery, certain studies suggest restenosis or reocclusion is a serious problem with traditional angioplasty treatment. While stents have been shown to help reduce restenosis and are used extensively, restenosis continues to occur at a significant rate. A new generation of stents that are coated with drugs targeted at preventing restenosis have recently shown some success. Early studies have shown significant reduction in restenosis when these drug eluting stents are used.

Conventional bypass surgery involves cutting open the patient’s chest, cutting through the sternum, usually connecting the patient to a heart-lung machine, stopping the heart, attaching a vein or artery removed from another part of the patient’s body to create a bypass around the diseased blood vessel and restarting the heart. According to the 2004 HSSU, an estimated 516,000 coronary artery bypass procedures were performed on 305,000 patients in the U.S. in 2001. Certain patients however are not suited for bypass procedures, including some who have previously undergone bypass surgery, patients with extremely diffuse diseases, patients with vessels that are too small to graft, patients with chronic obstructive pulmonary disease, some patients with diabetes, and others who are considered too ill to survive surgery.

We believe that TMR using the Heart Laser Systems is useful as a treatment for patients who have severe, stable angina and who are no longer candidates for either angioplasty or bypass surgery because of either extensive disease or small coronary arteries. The FDA has approved the Heart Laser Systems for such patients.

TMR is designed to be less invasive and less expensive than traditional bypass surgery, and may avoid the restenosis problem common with bypass surgery and balloon angioplasty by not targeting the coronary arteries for treatment.

TMR Using the Heart Laser Systems

The main challenge in treating atherosclerosis is to allow adequate blood to flow to the heart muscle without significantly damaging the heart. The conventional and newer techniques described above are used to bypass, reopen or widen blocked or narrowed arteries and can eventually fail due to restenosis or natural disease progression. TMR using the Heart Laser Systems involves a different technique whereby channels are created in the myocardium as a means of supplying oxygen-rich blood from the left ventricular chamber into the ischemic myocardium. TMR does not target the coronary arteries for treatment.

Heart muscle must be constantly supplied with oxygen in order to function effectively. Oxygen is delivered to the myocardium by blood, which is distributed to the myocardium through the right and left coronary arteries. If these arteries are narrowed or blocked as a result of atherosclerosis, sufficient oxygen-rich blood may be unable to reach the heart to satisfy the metabolic demands of the myocardium. Cardiovascular disease eventually may cause myocardial ischemia, often evidenced by severe and debilitating angina caused by lack of oxygen to the heart muscle, which can progress to myocardial infarction (the death of an area of the heart muscle). Advanced multi-vessel ischemic heart disease is typically treated with bypass surgery.

During a sole therapy TMR procedure, the patient is given general anesthesia and an incision is made in the patient’s side between the ribs, exposing the heart. The Heart Laser Systems are computer synchronized with the patient’s heartbeat, firing only when the left ventricle is filled with blood and is electrically insensitive. We believe that synchronization may reduce the risk of arrhythmias (irregular heartbeats) and their associated morbidity and mortality. Research studies conducted by the Texas Heart Institute in animal models indicated that performing TMR without synchronization may be associated with an increase in life threatening arrhythmias. The synchronization technology is covered under a patent that we own. The Heart Laser Systems are capable of creating a transmural channel in less than 0.1 second with a single laser pulse in a patient whose heart has not been stopped and who has not been placed on a heart-lung bypass machine. The surgeon can vary the pulse width of the laser using a touch key control panel to accommodate for the thickness of the patient’s heart wall. Transesophageal echocardiography is used to confirm that complete channels are made by the laser. Generally, 20 to 40 new channels are created during the procedure.

We believe that in addition to providing new direct pathways for blood to reach the ischemic myocardium, that the creation of TMR channels using The Heart Laser Systems also promotes angiogenesis, the formation of new blood vessels.

Potential Benefits of TMR

In September 2001 long term follow-up data was published in Circulation, the official journal of the American Heart Association, on eligible patients from our FDA clinical studies. The long-term TMR analysis included 78 patients at nine hospitals. Each patient had been suffering from chronic angina and from severe coronary artery disease (“CAD”) before receiving treatment with the HL1. The average age of the patients at enrollment was 61. The average preoperative angina class for the group was 3.7 out of a maximum of 4 (angina is measured in classes from one to four, one being the least painful and four being the most painful). After an average of 55 months following the TMR procedure, the group’s average angina class improved from 3.7 to 1.6. This was virtually unchanged from the 1.5 average angina class reported at 12 months following the TMR procedure. In fact, five years after having the TMR procedure with the HL1, 17% of the patients reported having no angina and 64% were in angina class 1 or 2.

Based on clinical results to date, we believe that TMR using the Heart Laser Systems provides a number of benefits, although no assurance can be given that any of the mentioned benefits will be received by patients and no assurance can be given that the FDA will approve additional indications for use of the Heart Laser Systems or that the FDA will not withdraw or alter its current approval. These current anticipated benefits include:

Therapy for Patients Not Suitable for Coronary Bypass. The FDA has approved the use of the Heart Laser Systems for patients who have stable angina (Canadian Cardiovascular Society Class III or IV) refractory to medical treatment and secondary to objectively demonstrated coronary artery atherosclerosis and with a region of the myocardium not amenable to direct coronary revascularization.

Potentially Reduced Hospital Readmission Costs. We believe that TMR is a cost effective treatment based on studies indicating that patients who receive TMR have fewer readmissions to the hospital for chest pain than those who receive only drug therapy.

Potential Delivery Mechanism for Angiogenic Agents. The TMR therapy utilizing the Heart Laser Systems may have the potential, with future development, to deliver angiogenic agents, which may assist in the treatment of CAD. This potentially could be accomplished through the use of standalone devices or by a device integrated into the current Heart Laser System handpieces that would, concomitantly with the TMR therapy, inject these agents into the myocardium.

Potential Angiogenic Response Stimulator. With additional clinical research, TMR therapy potentially could be found to be synergistic with delivered growth factors, which may prove useful in treating patients with CAD.

Cardiac Arrhythmias – Current Treatments

The heart is an electromechanical pump that contracts in a specific manner to efficiently pump blood throughout the body. The heart pumping is controlled by electrical signals that are generated in the right atrium of the heart and travel throughout the heart by way of an electrical conduction network. This system carries the electrical signals in a systematic way that results in a normal heartbeat. A failure in this conduction system usually results in an arrhythmia. An arrhythmia is an abnormal heart rhythm that can adversely affect the heart’s performance.

Several different types of arrhythmias can occur in the human heart. They can occur both in the ventricles and the atria and can be either fast heart rate (tachycardia) or slow heart rate (bradycardia). The most common sustained cardiac arrhythmia is an atrial tachycardia called atrial fibrillation (“AF”) that is characterized by the irregular contractions and/or very rapid beating of the atria. During AF, instead of a single smooth wave of contraction, the electrical conduction does not operate normally and a storm of electrical energy spreads in random loops across both atria causing rapid, uncoordinated contractions.

Today AF affects an estimated 5 million people worldwide including an estimated 2.2 million Americans, and we believe that there are 200,000 to 400,000 new cases diagnosed annually in the U.S. The condition can cause fatigue, dizziness, stroke and in extreme cases death if untreated. It is now understood that AF contributes to 15% to 20% of all strokes, and the need for life-long drug therapy can significantly impair the quality of life for patients.

Drug therapy is currently the standard of care for AF, and it is usually life-long. Patients are usually placed on rhythm control or rate control plus anticoagulation drugs, the former of which to manage arrhythmia and the latter to reduce the patient’s stroke risk. This type of therapy does not cure AF, but does help to reduce its effects. Anti-arrhythmic drugs have not proven highly successful to date.

The surgical Cox-Maze procedure is currently the most effective cure for AF with a reported success rate of over 95%. This is an extremely invasive, open-heart procedure that involves dissecting the atrium with a scalpel and sewing it back together to block the errant electrical signals allowing the heart to return to its normal rhythm. Because of its invasiveness and technical difficulty, we believe only about 100 Cox-Maze procedures are performed annually in the U.S.

The success of the Cox-Maze procedure has led surgeons and companies to develop and refine less invasive techniques that can deliver similar outcomes without the risks and the costs. These new approaches include the substitution of alternative energy sources for the surgical incision in the Cox-Maze procedure, such as radio-frequency, microwave, laser, cryo-therapy and ultrasound. Recent clinical results indicate that these alternative energy sources can reproduce much of the success of the surgical Cox-Maze procedure with significantly less trauma, including operating through minimally invasive incisions and on a beating heart. While most of these techniques are relatively new and are not fully developed, cure rates with these new devices are reported to exceed 80%.

AF surgery with these devices can be performed from the inside of the arrested heart (endocardially) in conjunction with other cardiac procedures or, with some of these devices, from the outside of the heart (epicardially)

while it is beating in a minimally invasive procedure. Since AF typically occurs in 30% to 45% of patients with mitral valve disease and the atrium is usually opened to repair or replace a mitral valve, the initial surgical market for these new procedures is expected to be in combination with mitral valve surgery.

Cardiac Tissue Ablation Using the Optimaze System

The Optimaze System being developed is a laser-based device that uses a 60-watt, 980nm diode laser as its power source. The laser power is delivered to various handpieces through a flexible optical fiber. The diode wavelength corresponds to a water absorption peak and causes tissue ablation by dielectric heating.

The key proprietary technology for this system is in the diffusing tip, which allows the surgeon to lay a linear lesion on the atria so that lesions as long as 5 cm are possible. The tip has a gold foil reflector that directs the laser power towards the heart. The tip is also malleable to allow different shaped lesions to be made.

The goal of laser ablation on cardiac tissue is to transmurally render specific cells incapable of conducting electrical cardiac signals without damaging adjacent tissues and other structures. When infrared laser energy is directed at the target tissue, water molecules in the tissue absorb the energy, generate heat and cause surrounding tissue to photocoagulate. The coagulated tissue forms lesions that block the conduction of errant electrical impulses, similar to the scalpel cuts in the Cox-Maze procedure.

In a study performed at Columbia University using the Optimaze System, endocardial ablations were performed on 12 dogs. All of the lesions were transmural, all were effective and there were no complications from collateral injury.

We believe some of the beneficial features of the Optimaze System are:

• It lends itself to minimally invasive procedures;

• It can perform ablation either endocardially or epicardially;

• Laser technology creates uniform lesions at a precise depth;

• It produces lesions up to 5 cm in length;

• It targets tissue with a high degree of accuracy thereby avoiding damage to surrounding structures; and

• It can create lesions in fatty hearts.

Potential Benefits of Cardiac Tissue Ablation

The most time-consuming aspect of the Cox-Maze procedure is the need to create numerous incisions in the atria, essentially taking apart the tissue like a jigsaw puzzle and then meticulously sewing it back together. In addition, the procedure must be done on a stopped heart that is on cardiopulmonary bypass. As the new cardiac ablation devices are perfected, the goal will be to match the AF cure rate obtained with the Cox-Maze procedure with a minimally invasive, easy to perform, low-cost procedure.

We believe that the Optimaze System is positioned to solve many of the problems with the Cox-Maze procedure. When using this system, the atria do not have to be cut apart and sewn back together. Electrical path blocking lesions can be made from the inside of the atria if the procedure is being done in conjunction with a valve procedure or potentially from the outside of the heart, while it is beating, without making any incisions in the atria.

The fact that this procedure has the potential to be performed minimally invasively on a beating heart and can have high cure rates, would make it an attractive alternative for many patients with AF.

Sales and Marketing Strategy

TMR Products – Sales Channel

We sell our TMR products principally through key distributors throughout the world. In the U.S., we have appointed Edwards as our exclusive distributor for the HL2 and all TMR disposable procedure kits. Edwards uses a direct sales force comprised of individuals with a high degree of professionalism and experience in the cardiovascular device business to market our TMR products in the U.S.

Outside the U.S., we have established an independent distributor network to market our TMR products, although in some areas, principally Europe, we continue to sell our TMR products directly to hospitals.

International sales (by origin) accounted for 6%, 5% and 14% of our total revenue in 2003, 2002 and 2001, respectively. We had no sales by origin in Canada, our jurisdiction of incorporation.

We sell our TMR products to both Edwards and our international distributors at a discount off list price.

Cardiac Tissue Ablation Products – Sales Channel

Edwards is our exclusive worldwide distributor for all surgical cardiac ablation products. By agreement, they are prohibited from offering for sale any directly competitive surgical products without first offering such competitive products to us to manufacture.

The Optimaze System currently is only approved for marketing in the United States. We believe we will be able to secure the regulatory approval (CE Mark) necessary to market this product throughout the European Union (EU) in 2005.

We understand that Edwards will use their direct sales force to market the Optimaze System in the United States. Internationally we understand that they will use both a direct sales force and third party distributors depending on the country they intend to market the product.

Edwards Marketing Programs

Edwards determines the programs, including sale, lease, rental and usage based offerings that it believes will be most effective in the U.S. in selling our products to hospitals.

Edwards’ marketing efforts are directed at cardiothoracic surgeons, whose influence is believed to be critical in a hospital’s decision to purchase our products. In addition, Edwards emphasizes educating hospital administration and referring physicians, with a focus on promoting the economics and viability of the medical treatments using our products.

Edwards also currently conducts Center of Excellence training programs across the country (i) to facilitate increased surgeon training for potential sales closure, (ii) to facilitate new site initiation, and (iii) to increase the number of surgeons trained in the use of our products. These training programs are focused on educating prospective surgeons, as well as surgeons from new and existing customer sites. These comprehensive programs facilitate interaction among experienced users enabling them to discuss best practices and focus on ensuring the best possible patient outcomes, including intensive discussions on patient selection and management. Course participants often view live, narrated procedures via closed circuit television. Actual hands on training is also provided in the use of our products.

Supporting Edwards’ direct sales force is a promotional program that consists of electronic and print media advertising, public relations, direct mail, trade shows and educational symposia, all focused on disseminating critical information to decision makers and key purchase influencers. No assurance can be given that such programs will

continue or be implemented successfully by Edwards.

Products and Customers

We market one principal product line, which consists of two patented high-powered carbon dioxide laser systems known as the Heart Laser Systems. Approximately 95%, 92% and 90% of our revenues for the years ended December 31, 2003, 2002 and 2001, respectively were derived from the sales and service of our Heart Laser Systems.

During 2003, 2002 and 2001, sales to Edwards accounted for 89%, 87% and 68%, respectively, of our total revenues.

Manufacturing

We manufacture and test our products at our facility in Franklin, Massachusetts, approximately 40 miles west of Boston. We believe that our manufacturing capacity will be sufficient to meet market demands anticipated in the coming year for all our products.

We purchase components for our Heart Laser Systems from a number of sources, and management believes that most, but not all, components are available from multiple sources. We expect we will be able to do the same for the Optimaze System. Should the supply of certain critical components be interrupted or become unavailable, we may not be able to meet demand for our products, which could have a material adverse effect on our business and results of operations.

Our manufacturing facilities are subject to periodic inspection by regulatory authorities to ensure compliance with FDA and European Union quality system regulations.

Government Regulation

The Heart Laser Systems and the Optimaze System, as well as other medical devices that we have or may develop, are subject to extensive regulation by the FDA and other regulatory authorities in the U.S. and abroad. The Federal Food, Drug, and Cosmetic Act (the “FDC Act”) and other federal and state statutes and regulations govern the research, design, development, manufacturing, preclinical and clinical testing, installation, storage, packaging, recordkeeping, servicing, labeling, distribution and promotion of medical devices in the U.S. Our laser products are subject to additional FDA regulation under the radiation health and safety provisions of the FDC Act, which imposes labeling and other safety requirements related to radiation hazards.

As a device manufacturer, we are also required to register with the FDA. As such, we are subject to inspection on a routine basis for compliance with the FDA’s Quality Systems regulations. These regulations require that we manufacture our products and maintain our documents in a prescribed manner with respect to manufacturing, testing and control activities. Further, we are required to comply with various FDA requirements for reporting. The FDC Act and medical device reporting regulations require that we provide information to the FDA on death or serious injuries alleged to have been caused or contributed to by the use of our products, as well as product malfunctions that would likely cause or contribute to death or serious injury if the malfunction were to recur. The FDA also prohibits an approved device from being marketed for unapproved uses. Our product promotion and advertising is subject to continuing FDA regulation. Our laser products are subject to periodic inspection under the radiation health and safety provisions of the FDC Act for compliance with labeling and other safety regulations. The failure to comply with the applicable regulatory requirements may subject us to a variety of administrative or judicially imposed sanctions, including the FDA’s refusal to approve pending or supplemental applications, withdrawal of an approval or clearance, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, and civil and criminal penalties against that company or its officers, directors or employees. Failure to comply with regulatory requirements could have a material adverse effect on our business, financial condition and results of operations.

We intend to continuously improve our products after market introduction and may therefore submit future Investigational Device Exemption, Pre-Market Notification (“510(k)”), Pre-Market Approval (“PMA”), and PMA supplement applications to the FDA. No assurance can be given that clearance or approval of such new applications will be granted by the FDA on a timely basis, or at all. Furthermore, we may be required to submit extensive preclinical and clinical data depending on the nature of the changes.

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the approval, manufacturing and marketing of drug products and medical devices. In addition, FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether legislative changes will be enacted, or FDA regulations, guidance, or interpretations changed, and what the impact of such changes, if any, may be.

Various foreign countries in which our products are or may be sold impose additional or different regulatory and testing requirements. The international regulatory approval process varies from country to country and is subject to change in a given country as regulatory requirements change. Thus, the time required for an approval may differ and there can be substantial delays in obtaining approval after the relevant applications are filed. There is no assurance that foreign regulatory authorities will approve the use or sale of our products in a particular country on a timely basis, or at all.

The FDA has approved the use of the Heart Laser Systems for patients who have stable angina (Canadian Cardiovascular Society Class III or IV) refractory to medical treatment and secondary to objectively demonstrated coronary artery atherosclerosis and with a region of the myocardium not amenable to direct coronary revascularization.

The FDA has given clearance to the Optimaze System under a 510(k) with indications for use as a surgical instrument for the coagulation of soft tissue, including cardiac tissue, in conjunction with or without endoscopic equipment in the contact or non-contact mode in open or closed surgical procedures.

Third-Party Reimbursement

Healthcare providers, such as hospitals and physicians, that purchase medical devices, such as the Heart Laser Systems and Optimaze System, for use on their patients generally rely on third-party payers, principally Medicare, Medicaid and private health insurance plans, to reimburse all or part of the costs associated with the procedures performed with these devices.

Currently Medicare coverage is provided for TMR when it is performed as both a sole therapy treatment and when used as an adjunct to bypass surgery. Certain private insurance companies and health maintenance organizations also currently provide reimbursement for TMR procedures performed with our products and physician reimbursement codes have been established for both surgical procedures; however we have limited data as to the breadth of this coverage for the TMR procedure by private insurance companies and health maintenance organizations. Cardiac tissue ablation procedures, such as those that would be performed using the Optimaze System, are also currently reimbursed by Medicare.

No assurance can be given, however, that these payers will continue to reimburse healthcare providers who perform TMR or cardiac tissue ablation procedures using our products now or in the future. Further, no assurance can be given that additional payers will reimburse healthcare providers who perform TMR or cardiac tissue ablation procedures using our products or that reimbursement, if provided, will be timely or adequate. In addition, the market for our products could be adversely affected by future legislation to reform the nation’s healthcare system or by changes in industry practices regarding reimbursement policies and procedures.

Notwithstanding the FDA approval and Medicare coverage for TMR procedures, we believe that concerns over the lack of a consensus view on the reason or reasons why a TMR procedure relieves angina in patients who undergo the procedure has limited demand for and use of the Heart Laser Systems. Although Medicare reimbursement began in July 1999, and many private insurance plans have begun reimbursing healthcare providers for TMR procedures using the Heart Laser Systems, we believe that hospitals may delay the implementation of a TMR program until there is documentation of the medical processes by which TMR procedures relieve angina, if ever.

Proprietary Processes, Patents, Licenses and Other Rights

It is our policy to file patent applications to protect our technology, inventions and product improvements. We also rely on trade secret protection for certain confidential and proprietary information.

Since April 1992, we have received 30 U.S. patents. These patents have terms which expire from 2009 through 2020 and cover, among other things, laser technology to create a pulsed, fast-flow laser system, the use of a laser on a beating heart to revascularize the heart using TMR related disposable components, and the system used to time the heart’s contractions to synchronize the laser firing at the correct time. We also have U.S. patent applications pending relating to technology used in the Heart Laser Systems, and technologies associated with percutaneous myocardial revascularization.

In January 1999, CardioGenesis Corporation, the only other current competitor in the TMR market, agreed to the validity and enforceability of certain of our patents in connection with a settlement of certain litigation between the companies. The patents, U.S. Patent No. 5,125,926 and related international patents, cover our proprietary synchronization technology, which we believe is a critical factor in increasing the safety of TMR procedures. We granted CardioGenesis a non-exclusive worldwide license to the patents in exchange for payment of a license fee and ongoing royalties over the life of the patents.

Although we believe our patents and the patents that we license from Edwards to be strong, litigation by a competitor seeking to invalidate these patents could have a material adverse effect on our business, financial condition and results of operations. No assurance can be given that the existing patents will be held valid if challenged, that any additional patents will be issued or that the scope of any patent protection will exclude competitors. The breadth of claims in medical technology patents involves complex legal and factual issues and therefore can be highly uncertain.

We also rely upon unpatented proprietary technology and trade secrets that we seek to protect, in part, through confidentiality agreements with employees and other parties. No assurance can be given that these agreements will not be breached, that we will have adequate remedies for any breach, that others will not independently develop or otherwise acquire substantially equivalent proprietary technology and trade secrets or disclose such technology or that we can meaningfully protect our rights in such unpatented technology. In addition, others may hold or receive patents that contain claims covering products developed by us or by Edwards.

We believe our patents, as well as those that we license from Edwards, to be valid and enforceable. However, there has been substantial litigation regarding patent and other intellectual property rights in the medical device industry. Litigation, which could result in substantial cost and diversion of our efforts, may be necessary to enforce our patents, to protect our trade secrets, to defend ourselves against claimed infringement of the rights of others and to determine the scope and validity of the proprietary rights of others. Adverse determinations in litigation could subject us to significant liabilities to third parties, require us to seek licenses from third parties and prevent us from manufacturing, selling or using our products, any of which could have a material adverse effect on our business, financial condition and results of operations.

Competition

TMR Products

The only competitor in the TMR market at this time is CardioGenesis. Although we do not believe it likely, because of the length of time and significant cost involved to conduct the necessary human clinical trials that would be required to secure approval from the FDA to market new TMR products, other companies may enter the TMR market in the future.

CardioGenesis has received FDA approval to market its holmium laser in the U.S. to perform TMR. CardioGenesis has also received CE Mark approval for their TMR system, which allows them to sell their product commercially in the European Union.

In addition to their TMR system, CardioGenesis has pursued a “percutaneous” method of performing myocardial revascularization, known as PMR. PMR procedures are performed via a catheter inserted through an incision in a patient’s leg. PMR is a less invasive method than TMR of creating channels in a human heart. CardioGenesis’ PMR system was reviewed by the FDA Circulatory System Devices Panel in July 2001. That panel, in a 7-2 vote, found the PMA application for their PMR system to be not approvable. Presently there are no FDA approved PMR devices in the marketplace.

We believe that the Heart Laser Systems are unique in the marketplace in that they are the only existing approved TMR products that can create a channel completely through the heart wall with a single laser pulse. Research conducted at the Texas Heart Institute in animal models has indicated that our synchronized, single pulse CO₂ laser may cause significantly less damage to the heart than a holmium laser used to perform TMR. Holmium lasers have different physical properties and interact differently with human tissue than our CO₂ laser. Holmium lasers currently used for TMR are not capable of creating a channel in one pulse, and must therefore use a fiber-optic probe that “drills” its way from the outside of the heart to the blood-filled left ventricle. The presence of the probe within the heart muscle may contribute to an increased risk of arrhythmias. Moreover, since four to seven firings are required to create a channel, channels formed in the heart wall by such holmium systems have been observed to be jagged and segmented. We believe that during 2003 Edwards continued to successfully differentiate our CO₂ laser and gained market share.

Many treatments are available for CAD. We believe that the primary competitive factors in the medical treatment of CAD are clinical safety and efficacy, product safety and reliability, regulatory approval, availability of reimbursement from insurance companies and other payers, product quality, price, reputation for quality, customer service and ease of use. We believe that our competitive success will be based on our ability to create and maintain scientifically effective and safe technology, obtain and maintain required regulatory approvals, obtain and maintain third party reimbursement for use of our products, attract and retain key personnel, obtain and maintain patent or other protection for our products and successfully differentiate, price, manufacture and market our products either directly or indirectly through outside parties.

The medical care products industry is characterized by extensive research efforts and rapid technological progress. New technologies and developments are expected to continue at a rapid pace in both industry and academia. Competition in the market for surgical lasers and for the treatment of cardiovascular disease is intense and is expected to increase. We believe that the Heart Laser Systems must compete not only with other TMR systems and potentially PMR systems, but also with medical management (drugs) and other coronary procedures (e.g., coronary bypass surgery, balloon angioplasty, atherectomy, laser angioplasty and stents, including new drug eluting stents that may significantly reduce restenosis). Many of the companies manufacturing these products have substantially greater resources and experience than we do. Such companies may succeed in developing products that are more effective, less invasive or less costly in treating coronary disease than the Heart Laser Systems and may be more successful than us in manufacturing and marketing their products. No assurance can be given that our competitors or others will not succeed in developing technologies, products or procedures that are more effective than any being developed by us or that would render our technology and products obsolete or noncompetitive.

Although we will continue to work to develop new and improved products, the advent of either new devices or new pharmaceutical agents could hinder our ability to compete effectively and have a material adverse effect on our business, financial condition and results of operations.

Cardiac Tissue Ablation Products

Drug therapy currently accounts for nearly half of the current treatment for AF. The therapy is individualized to the patient and usually focuses on number, duration and/or severity of symptoms instead of achieving a cure, which remains elusive. In addition, many patients do not respond to drug treatment. These and other factors have created an environment in which any new therapy that cures the condition in a safe and cost effective manner is likely to be adopted rapidly. Because of this, a number of companies have developed or are in the process of developing new devices for the treatment of AF.

Aside from drugs, there are a number of methods for treating AF, including surgical management, cardioversion, implantable devices and catheter-based ablation.

Surgical management includes the Cox-Maze procedure performed with either a scalpel or surgical ablation devices such as the Optimaze System. The Optimaze System is currently the only laser based surgical ablation system available. Other surgical ablation systems exist using other sources of energy such as radio-frequency (RF), microwave, cryo-ablation and ultrasound. Each of these systems has their advantages and disadvantages. A number of companies have these various devices that compete directly with the Optimaze System.

Surgical RF ablation can be performed using several different devices and techniques, including unipolar and bipolar devices and with or without irrigation. Companies with RF ablation devices include: Boston Scientific, Medtronic and AtriCure. A microwave surgical ablation device is currently being sold by Guidant/Afx. A cryo-ablation device is being sold by Cryocath. In addition, St. Jude Medical announced that it has invested in Epicor, a company which is developing a high intensity focused surgical ultrasound ablation device for treating AF. Since the surgical ablation business is relatively new, none of these devices has established itself as the market leader and the business is still evolving.

Cardioversion is another technique that is used to treat AF. In this procedure the patient’s heart is given a shock, either externally using a defibrillator device or internally using a catheter. This shock usually causes the heart to return to normal rhythm. It has been successfully used for secondary AF which has not persisted for a long time and is caused by a specific event such as surgery.

Implantable devices consist of pacemakers and internal cardioverter defibrillators (ICD’s). Pacemakers can be used in atrial overdrive pacing to try to overpower errant electrical signals or where the atrium electrical system is ablated and replaced with a pacemaker. ICDs are implanted in the patient to provide automatic internal cardioversion during episodes of AF. While this appears to work, patient intolerance for shock therapy for a non-life threatening condition has emerged as a serious limitation.

Catheter-based ablation technologies are similar to the surgical ablation technologies, except the ablation energy is delivered percutaneously through a catheter. A number of companies are developing devices for this procedure including: C.R. Bard, Johnson & Johnson, Biotronic, Cardima, Boston Scientific, Irvine Biomedical, Medtronic, St. Jude, Cryocath, CryoCor, Cardiofocus, Lightwave Ablation Systems and Transurgical. These devices use the same or similar energy sources as the surgical systems. Catheter ablation has proven to be more difficult than expected. Procedure times are high (4-6 hours) and recurrence rates are also high. It currently is not considered to be a cost effective technique. It is expected that many of these problems will eventually be solved and that in the five to ten year time frame, catheter based ablation will become widely used.

Research and Development

Research and development expenses were $980,000, $889,000 and $904,000 for the years ended December 31, 2003, 2002 and 2001, respectively. We expect to incur significant new research and development expenditures in the future in pursuit of our business strategy to broaden and diversify our product portfolio beyond our current TMR offerings. In particular, we expect our 2004 research and development expenditures to increase approximately $2.0 million compared to 2003 as we attempt to complete the development of the Optimaze System and advance certain other longer term research and development projects.

We continue to monitor technologies that may be applicable to TMR or cardiac ablation systems to keep us at the forefront of these fields. No assurance can be given that our research and development goals will be implemented successfully or that we will maintain our position in our market.

Employees

As of March 19, 2004, we had 32 full-time employees worldwide, including our executive officers. Of these, 9 are in general and administrative positions, 2 are involved in sales, 7 are involved in research and development, 7 are involved in manufacturing, 5 are involved in service and 2 are involved in quality and regulatory affairs. None of our employees are represented by a union. We consider our relationship with our employees to be good.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Since September 17, 1992, our common stock has traded on the American Stock Exchange (“AMEX”) under the symbol “PLC”. On March 1, 2004, the closing sale price of our common stock was $1.49 per share.

For the periods indicated, the following table sets forth the range of high and low sales prices for our common stock from January 1, 2002.

2002	High		Low

First Quarter	$	0.76	$	0.55
Second Quarter	$	0.67	$	0.38
Third Quarter	$	1.45	$	0.35

Second Quarter	$	0.74	$	0.41
Third Quarter	$	1.09	$	0.62
Fourth Quarter	$	1.85	$	0.88

As of March 1, 2004, there were 800 record holders of our common stock. We believe that there are approximately 11,775 beneficial owners of our common stock.

Dividends

We have never paid cash dividends. We currently intend to retain all future earnings, if any, for use in our business and we do not anticipate paying any cash dividends in the foreseeable future.

Canadian Tax Matters

Sales or Other Dispositions of Shares

Gains on sales or other dispositions of our shares by a non-resident of Canada are generally not subject to Canadian income tax, unless the holder realizes the gains in connection with a business carried on in Canada.

Passive Foreign Investment Company Implications

Because we are incorporated outside the United States, and our cash and investments are significant to our total assets, we must monitor rules regarding possible classification as a passive foreign investment company under U.S. Federal tax rules. While currently not classified as such, future classification as a passive foreign investment company could result in certain adverse tax consequences including, but not limited to, the allocation of a portion of the Company’s taxable income to our shareholders.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Critical Accounting Policies and Estimates

Our financial statements are based on the application of significant accounting policies, many of which require us to make significant estimates and assumptions (see Note 2 to the Consolidated Financial Statements). We believe that the following are some of the more material judgment areas in the application of our accounting policies that currently affect our financial condition and results of operations.

Inventories

Inventories are stated at the lower of cost or market value. A specific obsolescence allowance is provided for slow moving, excess and obsolete inventory based on our best estimate of the net realizable value of inventory on hand. Historically, we have found our reserves to be adequate.

Allowance for Doubtful Accounts

For our accounts receivable, we continuously monitor collections from customers, our principal customer being Edwards, and we maintain a provision for estimated credit losses based upon historical experience and any specific customer collection issues that we have identified. Historically, we have not experienced significant losses related to our accounts receivable. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Warranty and Preventative Maintenance Costs

We warranty our products against manufacturing defects under normal use and service during the warranty period. We obtain similar warranties from a majority of our suppliers, including those who supply critical Heart Laser System components. In addition, under the terms of our TMR distribution agreement with Edwards, we are able to bill Edwards for actual warranty costs, including preventative maintenance services, up to a specified amount during the warranty period.

We evaluate the estimated future unrecoverable costs of warranty and preventative maintenance services for our installed base of lasers on a quarterly basis and adjust our warranty reserve accordingly. We consider all available evidence, including historical experience and information obtained from supplier audits. In 2002, based upon this experience, we determined that the rate of Heart Laser System failure and cost per failure were lower than previously expected. As a consequence, during the third and fourth quarters of 2002, we reduced our warranty accrual by approximately $176,000. In the third quarter of 2003, we reduced the warranty accrual by approximately $40,000.

Revenue Recognition

We record revenue from the sale of TMR kits to Edwards at the time of shipment. Lasers are billed to Edwards in accordance with purchase orders we receive. Invoiced lasers are recorded as other current assets and deferred revenue on our consolidated balance sheet until such time as the laser is shipped to a hospital, at which time we record revenue and cost of revenue.

Under the terms of the Edwards TMR distribution agreement, once Edwards has recovered a prescribed amount of revenue from a hospital for the use or purchase of a laser, any additional revenues earned by Edwards are shared with us pursuant to a formula established in the distribution agreement. We only record our share of such additional revenue, if any, at the time the revenue is earned.

We record revenue from the sale of TMR kits and lasers to international distributors or hospitals at the time of shipment.

Prior to entering into the Edwards TMR distribution agreement, we installed lasers in hospitals under placement contracts that did not transfer substantial ownership of the equipment to the customer. Revenues from these transactions are recognized over the life of the placement agreement in accordance with the specific terms of the contract.

Revenues from service and maintenance contracts are recognized ratably over the life of the contract.

Installation revenues related to a laser transaction are recorded as a component of placement and service fees when the laser is installed.

Product Sales

Laser revenues, the largest component of product sales, decreased by $905,000 in 2003 as compared to 2002. This decrease is primarily attributable to a $1,035,000 decrease in domestic laser revenues, resulting from a decrease in the number of laser units sold. This decrease was offset in part by (1) a higher average domestic selling price on laser sales and (2) increased revenue sharing earned under the distribution agreement with Edwards. International laser revenue increased by $130,000 due to one laser sale in 2003.

Disposable TMR kit revenues, the second largest component of product sales, increased by $623,000 in 2003 as compared to 2002. This increase is attributable to an increase in the number of TMR kits shipped to Edwards.

Royalty revenue, a component of product sales, decreased $231,000 in 2003 as compared to 2002. This decrease is due to a decline in the guaranteed minimum royalties due from CardioGenesis. Minimum royalties were in effect through June 30, 2002, but ceased thereafter. Although CardioGenesis is required to pay an ongoing royalty on actual sales of covered products after June 30, 2002, we expect that until such time, if ever, that CardioGenesis obtains FDA approval for its PMR device, and provided that device remains a covered product under the terms of the license agreement, royalty revenue will be insignificant.

Other product sales decreased $13,000 in 2003.

Laser revenues, the largest component of product sales, increased by $180,000 in 2002 as compared to 2001. This increase is primarily attributable to an $857,000 increase in domestic laser revenues. The $857,000 increase in domestic laser revenues was due to (1) an increase in the number of laser units sold, (2) a higher average domestic selling price on laser sales and (3) increased revenue sharing earned under the distribution agreement with Edwards. The $857,000 increase in domestic laser revenues was partially offset by a $677,000 decrease in revenue generated from international laser sales.

Disposable TMR kit revenues, the second largest component of product sales, decreased by $453,000 in 2002 as compared to 2001. This decrease is primarily attributable to a decrease in the average domestic sales price of TMR kits sold to Edwards. This decrease in the average sales price of TMR kits sold to Edwards took effect in January 2002 when Edwards exercised a pre-existing option to assume full sales and marketing responsibility for the HL2 and associated TMR kits in the U.S. In connection with this option exercise by Edwards, Edwards retained an additional ten percentage points on revenue generated from U.S. TMR kit sales.

Royalty revenue, a component of product sales, decreased $249,000 in 2002 as compared to 2001. This decrease is due to a decline in the guaranteed minimum royalties due from CardioGenesis. Minimum royalties were in effect throughout all of 2001, but only the first two quarters of 2002.

Other product sales decreased by $28,000 in 2002.

Placement and Service Fees

Placement fees declined $211,000 in 2003 as compared to 2002. Approximately $124,000 of this $211,000 decline is attributable to a reduction in domestic placement fees. The $124,000 reduction in domestic placement fees is in part the result of various U.S. HL1 customers upgrading to the newer HL2. Each upgrade results in a laser sale to Edwards and a corresponding shift in recorded disposable TMR kit sales to these new HL2 customers which are recognized as product sales instead of placement fees. The remaining $87,000 of the $211,000 decline was the result of lower international placement contract fees due to decreased kit shipments to international placement contract customers.

Service fees increased $233,000 in 2003 as compared to 2002 due to more domestic lasers in service throughout 2003, which resulted in increased billings to Edwards for service contracts, installations and other service related calls.

Placement fees declined $565,000 in 2002 as compared to 2001. Approximately $336,000 of this $565,000 decline is attributable to a reduction in domestic placement fees. The $336,000 reduction in domestic placement fees is in part the result of various U.S. HL1 customers upgrading to the newer HL2. Each upgrade results in a laser sale to Edwards and a corresponding shift in recorded disposable TMR kit sales to these new HL2 customers which are recognized as product sales instead of placement fees. The remaining $229,000 of the $565,000 decline was the result of lower international placement contract fees due to decreased kit shipments to international placement contract

customers.

Service fees increased $173,000 in 2002 as compared to 2001 due to more domestic lasers in service throughout 2002, which resulted in increased billings to Edwards for installation, warranty and preventative maintenance services.

Gross Profit

Total gross profit was $4,991,000 or 60% of total revenues for the year ended December 31, 2003 as compared with gross profit of $4,746,000 or 54% of total revenues for the year ended December 31, 2002. The improvement in gross profit in 2003 as compared to 2002 is due to (1) higher disposable TMR revenues, (2) an increase in service related revenues and (3) higher average selling price and additional shared revenue on laser transactions. These increases were offset in part by (1) lower royalty revenues from CardioGenesis (2) a decrease in the number of laser sold, (3) a $136,000 decrease in benefit derived from reducing our warranty accrual and (4) reduced placement fees.

Total gross profit was $4,746,000 or 54% of total revenues for the year ended December 31, 2002 as compared with gross profit of $4,189,000 or 43% of total revenues for the year ended December 31, 2001. The improvement in gross profit in 2002 as compared to 2001 is due to (1) a higher average selling price and additional shared revenue on laser transactions, (2) manufacturing cost savings and improved product yields, (3) lower depreciation charges, (4) a $176,000 reduction in our warranty accrual and (5) an increase in service related revenues. These increases were offset in part by lower overall disposable TMR kit revenues, placement contract revenues and royalty revenues.

Selling, General and Administrative Expenses

The overall decrease in 2003 as compared to 2002 is primarily a result of reduced expenditures related to compensation, related benefits, depreciation, telephone and general corporate expenditures.

The overall decrease in 2002 as compared to 2001 is primarily attributable to (1) significantly reduced domestic sales and marketing expenditures as a result of the January 2002 exercise by Edwards of a pre-existing option to assume the U.S. sales and marketing responsibility for the HL2 and all TMR kits, (2) reduced international sales and marketing expenditures and (3) reduced administrative expenditures.

Research and Development Expenses

The largest component of our research and development expenses in 2003, 2002 and 2001 was the salaries and associated fringe benefits paid to our development staff.

The overall increase in 2003 as compared to 2002 is primarily related to consulting expenditures incurred in conjunction with our investigation and evaluation of new product development opportunities.

There were no significant changes in 2002 as compared to 2001 in any particular research and development expense related accounts, primarily because our development staffing levels remained unchanged.

We expect to incur significant new research and development expenditures in the future in pursuit of our business strategy to broaden and diversify our product portfolio beyond our current TMR offerings. In particular, we expect our 2004 research and development expenditures to increase approximately $2.0 million compared to 2003 as we attempt to complete the development of the Optimaze System and advance certain other longer term research and development projects.

Other Income

The largest component of other income is interest income earned on our cash balances.

In 2003, interest income remained relatively consistent compared to 2002. In addition, other income was lower due to a reduction in foreign currency transaction gains realized in our international operations.

The decrease in 2002 as compared to 2001 was a result of both a lower overall average investable cash balance and lower interest rates earned on these invested funds.

Liquidation of Subsidiary – Foreign Currency Loss

In 2003, we decided to close our Swiss subsidiary. In closing that subsidiary, we realized a non-recurring foreign currency translation loss of $257,000 in the year ended December 31, 2003.

Net Income (Loss)

The increase in net income in 2003 as compared to 2002 resulted primarily from higher gross margin and lower operating expenses, offset by the non-recurring foreign currency translation loss.

The net profit in 2002 as compared to a net loss in 2001 resulted primarily from higher gross margins and significantly reduced selling and marketing expenses as compared to 2001.

There was no provision for income tax for the year ended December 31, 2003 or 2002, despite a recorded net profit of $517,000 and $305,000, respectively, due to the utilization of U.S. net operating loss carryforwards being available to reduce taxable income.

We expect to incur a net loss in 2004, primarily as a result of our planned increased investments in research and development expenses, as discussed above.

Kit Shipments

We view disposable kit shipments to end users by Edwards as an important metric in evaluating our business. We believe kit shipments, although not a direct measure, are a reasonable indicator for the adoption of TMR as a therapy in the marketplace. Disposable kit shipments to end users are as follows:

	2003	% Increase (Decrease) over 2002		2002	% Increase (Decrease) over 2001		2001

Domestic	1,866	33	%	1,407	12	%	1,259
International	135	(44	)	242	(4	)	251
Total	2,001	21	%	1,649	9	%	1,510

Management believes the increase in domestic kit shipments in both 2003 and 2002 is due primarily to (1) an increase in the total number of installed lasers in the current year and (2) lasers installed and available for only a portion of the prior year being available to hospitals for all of the current year to perform TMR procedures. Management believes the decline in international kit shipments in both 2003 and 2002 is primarily due to our limited efforts to drive procedural adoption in the international markets.

Liquidity and Capital Resources

At December 31, 2003, we had cash and cash equivalents of $6,377,000, and in February 2004 we received another $4,533,333 in a transaction with Edwards (See Note 13 in the Consolidated Financial Statements). We have no debt obligations.

During the year ended December 31, 2003, we generated $607,000 from operating activities. Cash used in investing activities was approximately $91,000 consisting of the purchase of equipment. Cash used for financing activities was approximately $87,000, primarily consisting of the net proceeds of $50,000 obtained from sales of our common stock offset by a $137,000 reduction in secured borrowings. We believe that our existing cash resources will meet our working capital requirements for at least the next 12-24 months.

However, we are largely dependent on the success of Edwards’ sales and marketing efforts in the U.S. to continue to increase the installed base of HL2 lasers and substantially increase TMR procedural volumes and revenues. Should the installed base of HL2 lasers or TMR procedural volume not increase sufficiently, our liquidity and capital resources will be negatively impacted. Additionally, other unanticipated decreases in operating revenues or increases in expenses or further changes or delays in third-party reimbursement to healthcare providers using our products may adversely impact our cash position and require further cost reductions or the need to obtain additional financing. It is not certain that we, working with Edwards and our international distributors, will be successful in achieving broad commercial acceptance of the Heart Laser Systems, or that we will be able to operate profitably in the future on a consistent basis, if at all.

Some hospital customers prefer to acquire the Heart Laser Systems on a usage basis rather than as a capital equipment purchase. We believe this is the result of limitations many hospitals currently have on acquiring expensive capital equipment as well as competitive pressures in the marketplace. A usage business model may result in a longer recovery period for Edwards to recoup its investment in lasers it purchases from us. This could result in (1) a delay in our ability to receive additional shared revenue, if any, that we otherwise are entitled to receive under the terms of our distribution agreement with Edwards (see “Critical Accounting Policies and Estimates – Revenue Recognition”) and (2) a delay in the purchase of new lasers by Edwards if its installed base of placement lasers under usage contracts are under-performing and it chooses to re-deploy these lasers to other new hospital sites in lieu of purchasing a new laser from us. Our cash position and our need for additional financing to fund operations will be dependent in part upon the number of hospitals that acquire Heart Laser Systems from Edwards on a usage basis and the number and frequency of TMR procedures performed by these hospitals. We cannot predict whether a usage based sales model will be successful, whether implemented by us or Edwards.

Furthermore, we have recently undertaken a new business strategy that involves broadening and diversifying our product portfolio beyond our current TMR offerings, by developing or acquiring new and innovative medical devices to address cardiac and vascular related markets. We believe this strategy will result in our incurring losses for at least the next two years as we increase our investments in both manufacturing and research and development staff and capital equipment necessary to pursue these new strategic initiatives, including, but not limited to, the Optimaze System. We expect our capital expenditures to be in the range of $500,000 to $600,000. We cannot be certain that we will be successful in implementing our new business strategy or that future sales, if any, from these planned new products will recover the investments we plan to make. If we are unsuccessful in implementing our new business strategy our liquidity and capital resources will be adversely affected and we may need to obtain additional financing.

There can be no assurance that, should we require additional financing, such financing will be available on terms and conditions acceptable to us. Should additional financing not be available on terms and conditions acceptable to us, additional actions may be required that could adversely impact our ability to continue to realize assets and satisfy liabilities in the normal course of business. The consolidated financial statements set forth in this annual report do not include any adjustments to reflect the possible future effects of these uncertainties.

Contractual Obligations

Our long-term contractual commitments consist of an operating lease for our facility in Franklin, Massachusetts that expires in August 2006 and purchase commitments to make payments to suppliers. Future annual minimum payments are as follows:

(dollars in thousands)	Payment due by period
Contractual Obligations	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years

Operating Lease Obligations	$	762	$	285	$	286	$	191	$	—
Purchase Obligations	1,678		1,278		400		—		—
Total	$	2,440	$	1,563	$	686	$	191	$	—

Off-Balance Sheet Arrangements

None.

Certain Factors that May Affect our Future Results

The risks and uncertainties described below are not the only risks we face. Additional risks and uncertainties not presently known to us or currently deemed immaterial may also impair our business operations. If any of the following risks actually occur, our financial condition and operating results could be materially adversely affected.

Our company has a limited recent history of operating profits and we expect to incur significant operating losses in the near future

We do not expect our recent limited history of operating profits, which began in the second quarter of 2002, to continue in 2004 or for at least another twelve months thereafter. We expect to increase our spending significantly in 2004 in the areas of manufacturing and research and development, as we increase our manufacturing capabilities and development staff to work on the Optimaze System. Moreover, as we continue to pursue our new business strategy of acquiring or developing new medical devices to address cardiac and vascular related markets, we may continue to incur expenses that exceed the revenues we generate. We cannot provide any assurance that we will be successful with our new business strategy or that we will ever return to profitability.

Our company is currently dependent on one principal product line to generate revenues

We currently market one principal product line, which consists of two patented high-powered carbon dioxide lasers and related TMR disposable kits known as the Heart Laser Systems. Approximately 95% and 92% of our revenues in the years ended December 31, 2003 and December 31, 2002, respectively, were derived from the sales and service of our Heart Laser Systems. This absence of a diversified product line means that we are directly and materially impacted by changes in the market for Heart Laser Systems.

Our company is dependent on one principal customer

Pursuant to the terms of our amended TMR distribution agreement with Edwards, Edwards is our exclusive distributor for our HL2 and TMR kits in the United States. In addition, pursuant to the terms of our new distribution agreement with Edwards for the Optimaze System (as well as any other additional surgical products that we may develop for the treatment of atrial fibrillation or atrial flutter), Edwards is our exclusive worldwide distributor of those products. As a result of this relationship, Edwards accounted for 89% and 87% of our total revenue in the years ended December 31, 2003 and December 31, 2002, respectively, and we expect Edwards to account for the significant majority of our revenue in the future. If our relationship with Edwards does not progress

as anticipated or if Edwards’ sales and marketing strategies fail to generate sales of our products in the future, our revenue will decrease significantly and our business, financial condition and results of operations will be seriously harmed.

Our company is dependent on certain suppliers

Some of the components for our Heart Laser Systems, most notably the power supply and certain optics and fabricated parts for the HL2, and certain components for the Optimaze System, are only available from one supplier, and we have no assurance that we will be able to source any of our sole-sourced components from additional suppliers. We are dependent upon our sole suppliers to perform their obligations in a timely manner. In the past, we have experienced delays in product delivery from our sole suppliers and, because we do not have an alternative supplier to produce these products for us, we have little leverage to enforce timely delivery. Any delay in product delivery or other interruption in supply from these suppliers could prevent us from meeting our commercial demands for our products, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, we do not require significant quantities of any components because we produce a limited number of our products each year. Our low-quantity needs may not generate substantial revenue for our suppliers. Therefore, it may be difficult for us to continue our relationships with our current suppliers or establish relationships with additional suppliers on commercially reasonable terms, if at all, and such difficulties may seriously harm our business, financial condition and results of operations.

We must complete development of the Optimaze System and be able to manufacture it in high volumes at commercially reasonable costs

We must successfully complete development of the Optimaze System. We expect to outfit our facility with the necessary production and test equipment and train our employees on how to build the product. This will include the need to manufacture highly specialized disposable handpieces for which we have no comparable prior experience producing at any volume. Until such time as we become more proficient in these manufacturing methods, if ever, we may encounter problems related to:

• production yields;

• quality control;

• training;

• shortages of qualified personnel; and

• potential capacity constraints.

Such problems could severely affect our ability to adequately scale up production and meet demand for our products on a timely basis, which could harm our business, financial condition and results of operations.

We are dependent upon our key personnel and will need to hire additional key personnel in the near future

Our ability to operate our business successfully depends in significant part upon the retention and motivation of certain key technical, regulatory, production and managerial personnel and our ongoing ability to hire and retain additional qualified personnel in these areas. Competition for such personnel is intense, particularly in the Greater Boston area. We cannot be certain that we will be able to attract such personnel and the loss of any of our current key employees could have a significant adverse impact on our business.

Our company may be unable to raise needed funds

As of December 31, 2003, we had cash and cash equivalents totaling $6,377,000, and in February 2004 we received another $4,533,333 in a transaction with Edwards. Based on our current operating plan, we anticipate that our existing capital resources should be sufficient to meet our working capital requirements for at least the next 12-24 months. However, if our business does not progress in accordance with our current business plan, we may need

to raise additional funds in the future. We may not be able to raise additional capital upon satisfactory terms, or at all, and our business, financial condition and results of operations could be materially and adversely affected. To the extent that we raise additional capital by issuing equity or convertible securities, ownership dilution to our stockholders will result. To the extent that we raise additional capital through the incurrence of debt, our activities may be restricted by the repayment obligations and other restrictive covenants related to the debt.

In order to compete effectively, our current and future products need to gain commercial acceptance

TMR and surgical ablation for cardiac arrhythmias are still both emerging technologies. Our current and planned future products may never achieve widespread commercial acceptance. To be successful, we need to:

• demonstrate to the medical community in general, and to heart surgeons and cardiologists in particular, that TMR and surgical tissue ablation for cardiac arrhythmias are procedures that are effective, relatively safe and cost effective;

• support third-party efforts to document the medical processes by which TMR procedures relieve angina and surgical tissue ablation cures cardiac arrhythmias;

• have more heart surgeons trained to perform TMR procedures using the Heart Laser Systems and surgical tissue ablation procedures using the Optimaze System, assuming the latter becomes commercially available in the future; and

• maintain third-party reimbursement for both the TMR procedure and the use of surgical tissue ablation for the treatment of cardiac arrhythmias.

To date, only a limited number of heart surgeons have been trained in the use of TMR, and we are dependent on Edwards to expand related marketing and training efforts in the U.S. for the use of our current and planned future products.

Although the Heart Laser Systems have received FDA approval and the CE Mark, they have not yet received widespread commercial acceptance. In addition, although the Optimaze System has received FDA clearance, it has not yet secured the CE Mark and it is not yet ready for widespread commercialization. If we are unable to maintain regulatory clearances, secure the CE Mark for the Optimaze System or achieve widespread commercial acceptance of the Heart Laser Systems or the Optimaze System, our business, financial condition and results of operations will be materially and adversely affected.

Our competitor in TMR may obtain FDA approval to market a new device, the impact of which is uncertain on the future adoption rate of TMR

Our primary TMR competitor, CardioGenesis, is attempting to obtain FDA approval to market their PMR laser, which would provide a less invasive method of creating channels in the heart. If PMR can be shown to be safe and effective and is approved by the FDA, it would eliminate the need in certain patients to make an incision in the chest, reducing costs and speeding recovery. It is unclear what impact, if any, an approval of a PMR device would have on the future adoption rate for TMR procedures. If PMR is approved, it could erode the potential TMR market which would have a material adverse effect on our business, financial condition and results of operations.

Rapid technological changes in our industry could make our products obsolete

Our industry is characterized by rapid technological change and intense competition. New technologies and products and new industry standards will develop at a rapid pace, which could make our current and future planned products obsolete. The advent of new devices and procedures and advances in new drugs and genetic engineering are especially threatening. Our future success will depend upon our ability to develop and introduce product enhancements to address the needs of our customers. Material delays in introducing product enhancements may

cause customers to forego purchases of our product and purchase those of our competitors.

Many potential competitors have substantially greater financial resources and are in a better financial position to exploit marketing and research and development opportunities. In addition, we are aware that other companies are developing or already have developed proprietary systems for the treatment of cardiac arrhythmias, and specifically AF, that may be safer, clinically more effective, easier and more cost effective to use and, in the case of percutaneous devices, less invasive than the system we plan to develop.

We must receive and maintain government clearances or approvals in order to market our products

Our products and our manufacturing activities are subject to extensive, rigorous and changing federal and state regulation in the U.S. and to similar regulatory requirements in other major international markets, including the European Union and Japan. These regulations and regulatory requirements are broad in scope and govern, among other things:

• product design and development;

• product testing;

• product labeling;

• product storage;

• premarket clearance and approval;

• advertising and promotion; and

• product sales and distribution.

Furthermore, regulatory authorities subject a marketed product, its manufacturer and the manufacturing facilities to continual review and periodic inspections. We will be subject to ongoing FDA requirements, including required submissions of safety and other post-market information and reports, registration requirements, Quality Systems regulations, and recordkeeping requirements. The Quality Systems regulations include requirements relating to quality control and quality assurance, as well as the corresponding maintenance of records and documentation. Edwards, our distributor, depending on its activities, is also subject to certain requirements under the FDC Act and the regulations promulgated thereunder, and state laws and registration requirements covering the distribution of our products. Regulatory agencies may change existing requirements or adopt new requirements or policies that could affect our regulatory responsibilities or the regulatory responsibilities of a distributor like Edwards. We may be slow to adapt or may not be able to adapt to these changes or new requirements.

Later discovery of previously unknown problems with our products, manufacturing processes, or our failure to comply with applicable regulatory requirements may result in enforcement actions by the FDA and other international regulatory authorities, including, but not limited to:

• warning letters;

• patient or physician notification;

• restrictions on our products or manufacturing processes;

• voluntary or mandatory recalls;

• product seizures;

• refusal to approve pending applications or supplements to approved applications that we submit;

• refusal to permit the import or export of our products;

• fines;

• injunctions;

• suspension or withdrawal of marketing approvals or clearances; and

• civil and criminal penalties.

Should any of these enforcement actions occur, our business, financial condition and results of operations could be materially and adversely affected.

To date, we have received the following regulatory approvals for our products:

Heart Laser Systems

United States — We received FDA approval to market the HL1 Heart Laser System in August 1998 and the HL2 Heart Laser System in January 2001. However, although we have received FDA approval, the FDA:

• has restricted the use of the Heart Laser Systems by not allowing us to market these products to treat patients whose condition is amenable to conventional treatments, such as heart bypass surgery, stenting and angioplasty; and

• could impose additional restrictions or reverse its ruling and prohibit use of the Heart Laser Systems at any time.

Europe — Although we have the ability to market our Heart Laser System in the European Union, individual members of the European Union could, and France has, prohibited commercial use of the Heart Laser Systems.

We received the CE Mark from the European Union for the HL1 and HL2 in March 1995 and February 2001, respectively. However:

• the European Union could impose additional restrictions or reverse its ruling and prohibit use of the Heart Laser Systems at any time; and

• other European Union countries could prohibit or restrict use of the Heart Laser Systems.

Japan — We cannot market our product in Japan until we receive government approval.

We believe that Japan represents the largest potential market for the Heart Laser Systems in Asia. Prior to marketing the Heart Laser Systems in Japan, we must receive approval from the Japanese government. This approval requires a clinical study in Japan with at least 60 patients. A study was completed in 1998 with the HL1. Although the results of this study have been submitted to the Japanese government, we do not know whether the clinical study will be sufficient or when, if ever, we will receive approval to sell the HL1 in Japan. In addition, it is unclear what impact the introduction of the HL2 into the U.S. and other international markets will have on our ability to market the HL1 in Japan.

Optimaze System

United States — The FDA has given clearance to the Optimaze System under a 510(k) with indications for use as a surgical instrument for coagulation of soft tissue, including cardiac tissue, in conjunction with or without endoscopic equipment in the contact or non contact mode in open or closed surgical procedures. However, as the Optimaze System is still being developed, it is not yet deemed ready for commercial use in the U.S.

In addition, although we have received clearance from the FDA only for the indications of use stated above, physicians, under the practice of medicine exception, may use the Optimaze System in any manner they choose in treating an individual patient, including using the device to treat patients with AF. However, neither we nor Edwards have conducted any clinical trials designed to obtain data to submit to the FDA for the purpose of obtaining a specific indication for use of the Optimaze System that would allow us to make claims or otherwise market this device for the treatment of AF. We are aware of at least one company which has indicated they have submitted data to the FDA in support of a labeling claim that, if clearance is obtained, would allow them to market

their device for the treatment of AF.

In the event this company or other competitors are successful in obtaining specific indications for use for their devices in the treatment of AF, our cardiac ablation products and specifically the Optimaze System may be at a competitive marketing disadvantage until such time, if ever, that Edwards conducts a clinical trial, submits sufficient data to the FDA by means of a new 510(k) and obtains clearance to market the Optimaze System for the treatment of AF. We cannot provide any assurance that Edwards will ever conduct such a clinical trial or, if they do, that the data they obtain and submit to the FDA will be sufficient for the FDA to expand the current indications of use and provide clearance for the Optimaze System to be marketed for the treatment of AF. Also, we cannot assure you that even if such clearance is obtained, that it will be obtained in a timely enough fashion for our products to remain competitive in the marketplace.

Europe — Once the Optimaze System is fully developed in accordance with our internal design control processes and we deem it ready for human use, it nevertheless cannot be marketed in the EU until such time as it receives CE Mark approval. We need to complete and submit the relevant technical documentation to the appropriate certifying body in order to be able to apply the CE Mark that, if granted, will enable the product to be distributed into the EU.

Results of a recent study commissioned by the FDA may affect reimbursement for our TMR procedure or result in other FDA actions

In November 2003, the results of a TMR study commissioned by the FDA were published in The Journal of the American College of Cardiology. This study found that a certain number of patients who received TMR treatment did not meet the medical criteria for which it was approved. We cannot assure you that:

• Medicare or private insurance companies might not review their reimbursement policies in light of this study and otherwise amend or eliminate reimbursement of the TMR procedure; and

• the FDA will not require us to modify the labeling on the Heart Laser Systems or take some other action as a result of this study, or that the demand for our products will not otherwise be affected.

Should either of these actions occur, our business, financial condition and results of operations could be materially and adversely affected.

Asserting and defending intellectual property rights may impact our results of operations

In our industry, competitors often assert intellectual property infringement claims against one another. The success of our business depends on our ability to successfully defend our intellectual property. Future litigation may have a material impact on our financial condition even if we are successful in marketing our products. We may not be successful in defending or asserting our intellectual property rights.

An adverse outcome in any litigation or interference proceeding could subject us to significant liabilities to third parties and require us to cease using the technology that is at issue or to license the technology from third parties. In addition, a finding that any of our intellectual property is invalid could allow our competitors to more easily and cost-effectively compete with us. Thus, an unfavorable outcome in any patent litigation or interference proceeding could have a material adverse effect on our business, financial condition or results of operations.

The cost to us of any patent litigation or interference proceeding could be substantial. Uncertainties resulting from the initiation and continuation of patent litigation or interference proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and interference proceedings may also absorb significant management time.

We may be subject to product liability lawsuits; our insurance may not be sufficient to cover damages

We may be subject to product liability claims. The United States Supreme Court has stated that compliance with FDA regulations will not shield a company from common law negligent design claims or manufacturing and labeling claims based on state rules. Such claims may absorb significant management time and could degrade our reputation and the marketability of our products. If product liability claims are made with respect to our products, we may need to recall the implicated product which could have a material adverse effect on our business, financial condition and results of operations. In addition, although we maintain product liability insurance, we cannot be sure that our insurance will be adequate to cover potential product liability lawsuits. Our insurance is expensive and in the future may not be available on acceptable terms, if at all. If a successful product liability claim or series of claims exceeds our insurance coverage, it could have a material adverse effect on our business, financial condition and results of operations.

We are subject to risks associated with international operations

A portion of our product sales are generated from operations outside of the U.S. Establishing, maintaining and expanding international sales can be expensive. Managing and overseeing foreign operations may be difficult and products may not receive market acceptance. Risks of doing business outside the U.S. include, but are not limited to, the following: agreements may be difficult to enforce and receivables difficult to collect through a foreign country’s legal system; foreign customers may have longer payment cycles; foreign countries may impose additional withholding taxes or otherwise tax our foreign income, impose tariffs or adopt other restrictions on foreign trade; U.S. export licenses may be difficult to obtain; and the protection of intellectual property in foreign countries may be more difficult to enforce. There can be no assurance that our international business will grow or that any of the foregoing risks will not result in a material adverse effect on our business or results of operations.

Because we are incorporated in Canada, you may not be able to enforce judgments against us and our Canadian directors

Under Canadian law, you may not be able to enforce a judgment issued by courts in the U.S. against us or our Canadian directors. The status of the law in Canada is unclear as to whether a U.S. citizen can enforce a judgment from a U.S. court in Canada for violations of U.S. securities laws. A separate suit may need to be brought directly in Canada.

Our stock price has historically fluctuated and may continue to fluctuate significantly in the future which may result in losses for our investors

Our stock price has been and may continue to be volatile. Some of the factors that can affect our stock price are:

• the announcement of new products, services or technological innovations by us or our competitors;

• actual or anticipated quarterly increases or decreases in revenue, gross margin or earnings, and changes in our business, operations, or prospects;

• speculation or actual news announcements in the media or industry trade journals about our company, our products, the TMR procedure or changes in reimbursement policies by Medicare and/or private insurance companies;

• announcements relating to strategic relationships or mergers;

• conditions or trends in the medical device industry;

• changes in the economic performance or market valuations of other medical device companies; and

• general market conditions or domestic or international macroeconomic and geopolitical factors unrelated to our performance.

The market price of our stock may fall if shareholders sell their stock

Certain current shareholders hold large amounts of our restricted stock, which they could sell in the public market from time to time. Sales of a substantial number of shares of our common stock within a short period of time could cause our stock price to fall. In addition, the sale of these shares could impair our ability to raise capital through the sale of additional stock.

The value of your common stock may decrease if other security holders exercise their options and warrants

As shown in the table below, as of March 19, 2004, we have reserved an additional 6,706,065 shares of common stock for future issuance upon exercise of outstanding options, warrants and shares purchasable under an employee stock purchase plan.

	Range of Exercise/ Conversion Prices	Weighted Average Exercise/ Conversion Price		Shares Reserved for Future Issuance
Options	$ .45 - $8.88	$	1.56	4,258,144
Warrants	$ 1.00 - $3.50	$	2.90	2,100,000
Employee Stock Purchase Plan				347,921

Total				6,706,065

We may issue additional options and warrants in the future. If any of these securities are exercised, you may experience significant dilution in the market value of your common stock.

We have no intention to pay dividends

We have never paid any cash dividends on our common stock. We currently intend to retain all future earnings, if any, for use in our business and do not expect to pay any dividends in the foreseeable future.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

A portion of our operations consists of sales activities in foreign jurisdictions. We manufacture our products exclusively in the U.S. and sell our products in the U.S. and abroad. As a result, our financial results could be significantly affected by factors such as changes in foreign currency exchange rates or weak economic conditions in the foreign markets in which we distribute our products. Our operating results are exposed to changes in exchange rates between the U.S. dollar and foreign currencies, especially the Swiss Franc and the Euro. When the U.S. dollar strengthens against the Franc or Euro, the value of foreign sales decreases. When the U.S. dollar weakens, the functional currency amount of sales increases. No assurance can be given that foreign currency fluctuations in the future may not adversely affect our business, financial condition and results of operations, although at the present we do not believe that our exposure is significant as international sales represented less than 6% of our consolidated sales in 2003. The Company does not hedge any balance sheet exposures and intercompany balances against future movements in foreign exchange rates.

Our interest income and expense are sensitive to changes in the general level of U.S. and foreign interest rates. In this regard, changes in U.S. and foreign interest rates affect the interest earned on our cash and cash equivalents. We do not believe that a 10% change to the applicable interest rates would have a material impact on our future results of operations or cash flows.

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act) occurred during the fiscal quarter ended December 31, 2003 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Auditors

The Board of Directors and Stockholders of
PLC Systems Inc.

We have audited the accompanying consolidated balance sheets of PLC Systems Inc. as of December 31, 2003 and 2002, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2003. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of PLC Systems Inc. at December 31, 2003 and 2002, and the consolidated results of its operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2003 in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

PLC SYSTEMS INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2003

1. Business

PLC Systems Inc. (“PLC” or the “Company”) is a medical device company that specializes in the design, development and manufacturing of a patented carbon dioxide (CO₂) laser and disposable handpieces, known as The Heart Laser System, that is used to treat patients with severe angina in a surgical procedure known as transmyocardial revascularization, or TMR. In the United States, the Company sells its TMR products to Edwards Lifesciences. Edwards has the exclusive right to market and distribute the Company’s TMR products to hospitals in the United States.

PLC’s current business strategy involves broadening and diversifying its product portfolio beyond its current TMR offerings, by developing or acquiring new and innovative medical devices to address cardiac and vascular related markets. Subsequent to December 31, 2003, the Company, in pursuit of its current business strategy, entered into a new agreement with Edwards to develop and manufacture a surgical cardiac ablation laser designed to treat cardiac arrhythmias. In conjunction with signing this new development and manufacturing agreement the Company also modified the terms of its existing TMR distribution agreement with Edwards in exchange for a cash payment of $4.5 million (see “Note 13 Subsequent Event” for a further description of this transaction).

Edwards is the Company’s largest shareholder, owning approximately 18% of its outstanding common stock as of December 31, 2003, and has a representative on the Board of Directors.

2. Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of PLC and its three wholly owned subsidiaries, PLC Medical Systems, Inc., PLC Sistemas Medicos Internacionais (Deutschland) GmbH, and PLC Medical Systems AG. During 2003, PLC Medical Systems AG was substantially liquidated resulting in the recognition of $257,000 of foreign currency translation losses. All intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents at December 31, 2003 and 2002 consist of investments in money market funds. These investments are carried at cost, which approximates fair value.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk include cash and cash equivalents and accounts receivable. The Company believes it minimizes its exposure to potential concentrations of credit risk by placing its cash equivalents in high-quality financial instruments with a high quality institution. At December 31, 2003 and 2002, the majority of the cash and cash equivalents balance was invested in a single money market account.

F-7

PLC SYSTEMS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

December 31, 2003

Beginning in 2001, the Company has had a concentration of credit risk due to its exclusive distributorship arrangement with Edwards in the U.S. Edwards accounted for 89%, 87% and 68% of the Company’s revenues for the years ended December 31, 2003, 2002 and 2001, respectively. Collateral is not required on the sales to Edwards. At December 31, 2003 and December 31, 2002, the Company had outstanding accounts receivable from Edwards totaling $1,101,000 and $1,220,000, respectively.

Allowance for Doubtful Accounts

For the Company’s accounts receivable, the Company continuously monitors collections from customers, its principal customer being Edwards, and maintains a provision for estimated credit losses based upon historical experience and any specific customer collection issues that the Company has identified. Historically, the Company has not experienced significant losses related to its accounts receivable. If the financial condition of its customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Inventories

Inventories are stated at the lower of cost (computed on a first-in, first-out method) or market value. A specific obsolescence allowance is provided for slow moving, excess and obsolete inventory based on management’s best estimate of the net realizable value of inventory on hand.

Equipment, Furniture, Leasehold Improvements and Long-Lived Assets

Equipment, fixtures and leasehold improvements are stated on the basis of cost. Depreciation is computed principally on the straight-line method for financial reporting purposes and on accelerated methods for income tax purposes.

Depreciation and amortization are based on the following useful lives:

Equipment		3-5 years
Office furniture and fixtures		5 years
Leasehold improvements		Life of lease

The Company reviews and evaluates long-lived assets for impairment on a regular basis. In the Company’s opinion, long-lived assets are not impaired as of the balance sheet dates presented.

Warranty and Preventative Maintenance Costs

The Company warranties its products against manufacturing defects under normal use and service during the warranty period. The Company obtains similar warranties from a majority of its suppliers, including those who supply critical Heart Laser System components. In addition, under the terms of our TMR distribution agreement with Edwards, the Company is able to bill Edwards for actual warranty costs, including preventative maintenance services, up to a specified amount during the warranty period.

The Company evaluates the estimated future unrecoverable costs of warranty and preventative maintenance services for its installed base of lasers on a quarterly basis and adjusts its warranty reserve accordingly. The Company considers all available evidence, including historical experience and information obtained from supplier audits.

Changes in the warranty accrual were as follows (in thousands):

	Year Ended December 31,

Balance, beginning of period	$	100		$	276
Change in liability for warranties issued during the period	19			—
Change in liability for pre-existing warranties	(59		)	(176		)
Balance, end of period	$	60		$	100

Revenue Recognition

The Company records revenue from the sale of TMR kits to Edwards at the time of shipment. Lasers are billed to Edwards in accordance with purchase orders that the Company receives. Invoiced lasers are recorded as other current assets and deferred revenue on the Company’s consolidated balance sheet until such time as the laser is shipped to a hospital, at which time the Company records revenue and cost of revenue.

Under the terms of the Edwards TMR distribution agreement, once Edwards has recovered a prescribed amount of revenue from a hospital for the use or purchase of a laser, any additional revenues earned by Edwards are shared with the Company pursuant to a formula established in the distribution agreement. The Company only records its share of such additional revenue, if any, at the time the revenue is earned.

The Company records revenue from the sale of TMR kits and lasers to international distributors or hospitals at the time of shipment.

Prior to entering into the Edwards TMR distribution agreement, the Company installed lasers in hospitals under placement contracts that did not transfer substantial ownership of the equipment to the customer. Revenues from these transactions are recognized over the life of the placement agreement in accordance with the specific terms of the contract.

Revenues from service and maintenance contracts are recognized ratably over the life of the contract.

Installation revenues related to a laser transaction are recorded as a component of placement and service fees when the laser is installed.

Foreign Currency Translation

Assets and liabilities are translated into U.S. dollars at current exchange rates, while income and expense items are translated at average rates of exchange prevailing during the year. Exchange gains and losses arising from translation are accumulated as a separate component of stockholders’ equity. During 2003, the liquidation of PLC Medical Systems AG was substantially complete, resulting in the recognition of $257,000 of foreign currency translation losses. Gains and losses from foreign currency transactions are recorded as other income, net, in the accompanying statements of operations and are not material.

Earnings (Loss) per Share

In 2003 and 2002, basic earnings per share have been computed using only the weighted average number of common shares outstanding during the period while diluted earnings per share have been computed using the weighted average number of common shares outstanding during the period plus the effect of outstanding stock options and warrants using the treasury stock method.

F-9

PLC SYSTEMS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

December 31, 2003

In 2001, basic and diluted loss per share have been computed using only the weighted average number of common shares outstanding during the period without giving effect to any potential future issues of common stock related to stock option programs and warrants since their inclusion would be antidilutive.

In calculating diluted earnings per share, the dilutive effect of stock options and warrants is computed using the average market price for the respective period. For the years ended December 31, 2003 and 2002, 3,866,000 and 4,341,000 shares attributable to outstanding stock options and warrants were excluded from the calculation of diluted earnings per share because the effect was antidilutive. The following table sets forth the computation of basic and diluted earnings per share:

Stock Based Compensation

The Company grants stock options for a fixed number of shares to employees and certain other individuals with exercise prices equal to the fair value of the shares at the dates of grant. The Company has adopted the disclosure only provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-based Compensation (“FAS 123”), and will continue to account for its stock option plans in accordance with the provisions of Accounting Principles Board Opinion 25, Accounting for Stock Issued to Employees. In addition, the Company has made the appropriate disclosures as required under Statement of Financial Accounting Standards No. 148, Accounting for Stock-Based Compensation–Transition and Disclosure.

5. Stockholders’ Equity

In January 2001, the Company issued 5,333,333 shares of common stock to Edwards at $.75 per share resulting in net proceeds of approximately $3,898,000. Edwards has certain preemptive rights to maintain their ownership position relative to future stock offerings. The Company also issued 1,000,000 warrants to purchase shares of common stock at $1.50 per share, 1,000,000 warrants to purchase shares of common stock at $2.50 per share, and 1,000,000 warrants to purchase shares of common stock at $3.50 per share. These warrants expire in January 2004, January 2005 and January 2006, respectively. In connection with this transaction, the Company issued to a financial advisor a warrant to purchase 100,000 shares at $1.00 per share, expiring January 2006. The 1,000,000 warrants due to expire January 2004 did so unexercised.

At December 31, 2003, there were 7,864,399 shares of authorized but unissued common stock reserved for issuance under all stock option plans, the employee stock purchase plan and stock warrants.

The Company has unlimited authorized shares of preferred stock. The Board of Directors is authorized to fix designations, relative rights, preferences and limitations in the preferred stock at the time of issuance.

The Company has never declared nor paid dividends on any of its capital stock and does not expect to do so in the foreseeable future.

6. Stock Option and Stock Purchase Plans

The Company’s 1995 Stock Option Plan (“1995 Plan”), 1997 Executive Stock Option Plan (“1997 Executive Plan”), 2000 Employee Stock Purchase Plan (“Purchase Plan”), 2000 Equity Incentive Plan (“2000 Plan”), 2000 Non-Statutory Stock Option Plan (“2000 Non-Statutory Plan”) and 2000 Non-Qualified Retention and Performance Equity Plan (“2000 Retention Plan”), collectively referred to as the “Plans”, allow for the granting of options aggregating 4,416,478 shares of common stock. In May 2003, the Company’s Board of Directors, through its Compensation Committee, approved an amendment increasing the number of shares of common stock authorized for issuance under the 2000 Plan from 500,000 to 1,500,000. Incentive stock options are issuable only to employees of the Company, while non-qualified options may be issued to non-employee directors, consultants, and others, as well as to employees. The options granted under all the Plans generally become exercisable ratably over one to four years from the date of grant, or based on the attainment of specific performance criteria, and expire ten years from the date of grant. In 2003, the Company’s 1993 Formula Stock Option Plan (the “Formula Plan”) and the 1993

F-12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

December 31, 2003

Stock Option Plan (“1993 Plan”), which allowed for the granting of options aggregating 1,000,000 shares of common stock, expired.

Annually, the Company grants 10,000 options to each of its non-employee directors who have vested in their initial option grant of 30,000 options. A director must attend at least 60% of all Board meetings, as well as committee meetings, to receive the grant. In addition, the Chairman of the Board receives an annual grant of 20,000 options. The options vest over one year on a quarterly basis and expire ten years from the date of grant. The exercise price is the fair market value of the Company’s common stock on the date of grant.

The per share exercise price of the common stock subject to an incentive stock option may not be less than the fair market value of the common stock on the date the option is granted. The Company must grant non-qualified options at an exercise price of at least 85% of the fair market value of the common stock.

In August 2002, the Company communicated to its domestic employees an offer to exchange certain employee stock options having an exercise price of $.75 or more per share previously granted to them in return for nonqualified stock options of the Company at an exchange ratio of one new option share for one eligible option share surrendered (the “Exchange Offer”). Each employee who accepted the Exchange Offer was required to exchange all option shares subject to each option grant that the employee surrendered for exchange and to forfeit certain stock options granted to him or her on or after February 26, 2002. Generally, the new options granted in this exchange will vest on a cumulative basis with one-sixth of the new option vesting on the date the new option is granted and the remaining portion of the new option vesting in five equal installments at the end of each six-month period thereafter.

The Company issued on or about March 26, 2003 new options to purchase 999,345 shares of the Company’s Common Stock in exchange for the options surrendered in this option exchange program. Because the new options were granted six months and a day from the cancellation, no compensation expense resulted from the grant of the new options.

The following is a summary of option activity under all Plans (in thousands, except per option data):

The Company has an Employee Stock Purchase Plan for all eligible employees. Under the Company’s Purchase Plan, shares of the Company’s common stock may be purchased at six-month intervals at 85% of the lower of the fair market value on the first or the last day of each six-month period. Employees may purchase shares having a value not exceeding 10% of their gross compensation during an offering period, subject to certain additional limitations. Under the Purchase Plan, employees of the Company purchased 78,832 shares of common stock in 2003, 85,495 shares of common stock in 2002 and 228,803 shares of common stock in 2001 at average prices of $0.51, $0.44 and $0.45 per share, respectively. At December 31, 2003, 347,921 shares were reserved for future issuance under the Purchase Plan.

7. Lease Receivables and Secured Borrowings

Prior to 2001, the Company entered into third-party financing arrangements whereby the Company received payment from a leasing company equal to the present value of guaranteed minimum procedure payments due from the customer after customer acceptance of the HL1. In transactions where the Company had transferred substantially all of the risks and rewards of ownership to the customer and the customer had accepted the HL1, the Company recognized revenues, which were reported as a component of product sales. The Company recognized a lease receivable equal to the present value of the guaranteed minimum lease payments until such time as the Company can legally isolate the lease receivables. The payment received from the leasing company was recognized as a secured borrowing. Interest income and interest expense related to the lease receivables and secured borrowing, respectively, are recognized over time using the effective interest method. Equal amounts of interest income and interest expense are included as a component of other income, net in the Consolidated Statement of Operations.

8. Lease Commitments

The Company leases its corporate office under an operating lease agreement which expires in August 2006. In addition to the minimum lease payments, the agreements require payment of the Company’s pro-rata share of property taxes and building operating expenses.

As of December 31, 2003, future minimum lease payments are estimated to be as follows (in thousands):

Year	Future Minimum Lease Payments
2004	285
2005	286
2006	191
	$	762

Total rent expense was $296,000 in 2003, $299,000 in 2002 and $362,000 in 2001.

9. Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets as of December 31 are as follows (in thousands):

	2003			2002
Net U.S. operating loss carryforwards	$	20,399		$	20,705
Net foreign operating loss carryforwards	460			1,903
Accrued expenses and reserves	688			171
Tax credits	1,005			831
Other	617			718

Total deferred tax assets	23,169			24,328
Valuation allowance	(23,169		)	(24,328		)

Net deferred tax assets	$	—		$	—

The valuation allowance decreased by approximately $1,159,000 in 2003 primarily due to net income offset in part by an increase in temporary differences associated with accrued expenses and reserves in 2003. The Company recorded the valuation allowance due to the uncertainty of the realizability of the related net deferred tax asset of $23,169,000.

Income (loss) before taxes consisted of the following (in thousands):

	2003			2002			2001
Domestic	$	1,098		$	638		$	(3,674	)

At December 31, 2003, the Company had U.S. net operating loss carryforwards available to reduce future taxable income of approximately $51 million, which expire at various dates through 2023. In addition, the Company had foreign net operating loss carryforwards of approximately $1.2 million.

10. Adjustment of Prior Period’s Cumulative Translation Adjustment

During 2003, PLC management discovered that certain balances associated with the foreign currency translation of previously liquidated subsidiaries remained inappropriately in the cumulative translation account within cumulative other comprehensive income. Such cumulative losses should have been recognized as other expenses in 1998. To properly reflect the impact of such losses on the accumulated deficit, the 2002 accumulated deficit and the cumulative translation account balances have been adjusted to correctly state both accounts as follows:

	2002 As Previously Reported			Correction of Prior Period Error			2002 As Adjusted
Common stock	$	93,586		—			$	93,586
Accumulated deficit	(85,698		)	(568		)	(86,266		)
Accumulated other comprehensive income	(1,163		)	568			(595		)
Total shareholders’ equity	$	6,725		$	—		$	6,725

The adjustment had no impact on 2002 net equity, net income or comprehensive income.

11. Segment Information

The Company operates in one industry segment - the development, manufacture and sales of medical lasers and related products. Net sales to unaffiliated customers (by origin) are summarized below (in thousands):

13. Subsequent Event

In February 2004, the Company signed an agreement with Edwards to assume development of a surgical cardiac ablation laser system designed to treat cardiac arrhythmias. Under the terms of the agreement, the Company will have exclusive manufacturing rights to build the new laser system and other related surgical products. The Company will be responsible, among other things, for ongoing research and development and manufacture of the product and for obtaining regulatory approvals and Edwards will be responsible for the approval, funding and conduct of any clinical studies designed to obtain data in support of a new product approval or clearance as required by the FDA or other regulatory body.

In conjunction with signing this new agreement, the terms of the Company’s TMR distribution agreement with Edwards were modified to (1) extend the term of the agreement until October 17, 2017 and (2) reduce the Company’s share of revenue on TMR kits sold to hospitals. The Company received as consideration a lump-sum payment of $4,533,333, which will initially be recorded as deferred revenue in its consolidated balance sheet. The Company expects to amortize the $4,533,333 into its consolidated statement of operations as revenue over the next seven years.
