ITEM 1.  BUSINESS

OVERVIEW

     CardioThoracic Systems Inc. ("CTS" or the "Company") develops, 
manufactures, and markets  proprietary, disposable instruments and systems 
for performing minimally invasive cardiothoracic surgery. The Company's 
products are designed to enable the majority of cardiothoracic surgeons, 
using their existing skills coupled with Company sponsored training, to 
perform Minimally Invasive Direct Coronary Artery Bypass ("MIDCAB-TM-") 
surgery, an emerging minimally invasive revascularization procedure performed 
on a beating heart. The MIDCAB procedure eliminates the need for a heart-lung 
machine and recent studies indicate that the MIDCAB procedure reduces the 
trauma, procedural costs and post-surgical complications associated with 
coronary artery bypass graft ("CABG") surgery while providing long-term 
procedural success rates comparable to CABG surgery. 
     
     The main components of the CTS MIDCAB-TM- System  include: the ACCESS 
PLATFORM, which is designed to maximize access to the chest cavity through a 
mini-thoracotomy; the STABILIZER, which is designed to isolate and minimize 
the motion of the diseased artery; the LIMA LIFT, which is designed to offset 
the ribs to provide a window into the chest cavity so the surgeon can harvest 
the internal mammary artery (IMA); and the LIMA-LOOP, which is designed to 
enable the surgeon to reach into the chest cavity through the 
mini-thoracotomy and help isolate the IMA for harvest.
     
BACKGROUND

     Heart disease is the leading cause of death in America, with the 
American Heart Association reporting in 1995 that an estimated 11.2 million 
Americans have a history of coronary artery or other heart disease. Each 
year, approximately 1.4 million patients undergo a revascularization 
procedure to treat coronary artery disease. Coronary artery disease 
(atherosclerosis) is caused by cholesterol and other fatty materials becoming 
deposited on the walls of blood vessels, which form a build-up known as 
plaque. The heart needs a constant supply of oxygen and nutrients, which are 
carried by the blood in the coronary arteries. The accumulation of plaque 
narrows the interior of the blood vessels, thereby reducing blood flow to the 
heart muscle (the myocardium). When blood flow to the heart muscle becomes 
insufficient, an injury occurs, which may result in a heart attack 
(myocardial infarction) and often death.
     
     The heart has three main branches of coronary arteries: the left 
anterior descending artery ("LAD"), which descends from the left across the 
heart; the right coronary artery ("RCA"), which extends from the right of the 
heart around to the back of the heart; and the left circumflex artery, which 
extends from the left of the heart around to the back of the heart. The LAD 
is the primary blood supply to the heart and supplies blood to a large amount 
of the myocardium. Studies indicate that restoring blood flow to the LAD is 
the single most important determinant of long-term, event-free survival. 
Traditional treatments for coronary artery disease include drug therapy, 
coronary artery bypass graft ("CABG") surgery and catheter-based treatments, 
including balloon angioplasty, atherectomy and coronary stenting. CABG bypass 
surgery is highly invasive and traumatic to the patient, but is considered 
the most effective and long-lasting treatment for severe coronary artery 
disease. While catheter-based treatments are less invasive, the procedures 
are limited by high rates of restenosis, a renarrowing of the treated 
coronary artery, which generally requires reintervention. Catheter-based


                                       3


treatments have been increasingly adopted because they are a less invasive 
treatment alternative. There are approximately 800,000 catheter-based 
procedures performed annually worldwide. Notwithstanding the introduction of 
less invasive catheter-based treatments, the Company believes that the number 
of patients treated by CABG surgery has continued to grow each year and that 
more than 600,000 CABG procedures are performed annually worldwide. The 
Company believes that many of the patients currently undergoing CABG surgery 
or catheter-based treatments are candidates for the MIDCAB procedure.
     
     DRUG THERAPY

     Drug therapy is a non-invasive treatment to improve blood flow and 
alleviate some of the symptoms associated with angina (chest pain). However, 
while some drug therapies may inhibit continued plaque build-up in the 
arteries, drug therapy is not a cure for heart disease. The various drugs 
utilized include nitroglycerin, beta blockers, calcium channel blockers and 
cholesterol lowering drugs. Although drug therapy is the least invasive 
treatment currently available, it is typically expensive because it must be 
chronically administered. Some patients suffer from side effects as well as 
require future interventional procedures.
     
     CORONARY ARTERY BYPASS GRAFT SURGERY

     CABG surgery is a treatment for severe cases of coronary artery disease 
in which blood vessel grafts are used to bypass the site of the blocked 
artery. This procedure restores blood flow by routing around a blockage using 
a healthy blood vessel from another part of the body. Although CABG surgery 
is highly effective in treating coronary artery disease, it is a highly 
invasive, traumatic and expensive procedure. In the United States the cost of 
undergoing CABG is approximately $36,000. The average post-operative hospital 
stay for a person undergoing a CABG procedure in the United States in 1994 
was five to seven days, and the average recuperation period following 
discharge from the hospital was approximately eight to ten weeks.
     
     The CABG procedure involves sawing the patient's sternum or breast bone 
in half, creating a twelve inch incision (sternotomy) for the purpose of 
exposing the patient's heart. The two halves are spread approximately six 
inches apart with a steel sternal retractor, and the heart is exposed. With a 
sternotomy, the heart is not directly under the incision and must be stopped 
prior to being moved into position for the procedure. Cannulae (plastic 
tubes) are inserted into the aorta and right atrium of the heart, a clamp is 
placed on the aorta to stop blood flow, and the heart is connected to a 
heart-lung machine to be slowly cooled and eventually stopped before the 
grafting can occur. The heart-lung machine is a series of interconnected 
specialty medical devices that together function as the patient's heart and 
lungs by temporarily circulating and oxygenating blood while the patient's 
own heart and lungs are rendered inactive. The patient's blood is circulated 
through plastic tubes to reservoirs in the heart-lung machine where carbon 
dioxide is removed, oxygen is replaced, and temperature is controlled. The 
patient's circulation is maintained on the external equipment throughout much 
of the CABG procedure, which averages three to six hours, depending on the 
patient's condition and number of grafts that must be created. Often patients 
undergo multiple vessel procedures, which may involve harvesting a saphenous 
vein from the leg and bypassing several blockages to achieve 
revascularization. When a saphenous vein is used as a graft, a continuous 
incision is often made from the ankle to the thigh of a patient's leg, the 
saphenous vein is dissected and removed, and the wound is sutured closed. A 
study involving over 1,000 patients indicates that the open harvesting of the 
saphenous vein (saphenectomy) results in wound healing impairment in 
approximately 24% of patients. As an


                                       4


alternative to bypassing the blockage with a saphenous vein graft, an 
internal mammary artery ("IMA"), can be grafted directly on the coronary 
artery, bypassing the blocked section. At the conclusion of the CABG 
procedure, cannulae and the heart-lung machine are removed, the sternal 
halves are tied together with steel wire, and the skin is closed with suture 
material.
     
     Despite the invasiveness and trauma of the procedure, CABG is considered 
the most effective and long lasting treatment for severe coronary artery 
disease. Over 85% of bypass grafts formed from saphenous veins are patent 
(open) one year after surgery and over 60% are patent ten years after 
surgery. Grafts using the internal mammary arteries have patency rates of 
over 85% ten years after surgery and are well documented as being highly 
resistant to atherosclerosis.
     
     While every effort is made to minimize potential adverse effects from a 
procedure as traumatic as CABG surgery, published studies have shown that 
approximately 68% of all CABG surgeries have some complications. Some of the 
most severe complications can be attributed to the heart-lung machine 
including strokes, multiple organ dysfunction, inflammatory complications, 
respiratory failure and post-operative internal bleeding complications. It is 
estimated that stroke, which can have devastating functional consequences, 
occurs in approximately 5% of all CABG procedures. Another common 
complication of the use of the heart-lung machine is cognitive dysfunction, 
with patients experiencing significant loss of memory, attention span, verbal 
fluency, and psychomotor speed, even as long as six months after CABG 
surgery, regardless of attempts to mitigate or decrease the heart-lung 
machine time and trauma.
     
     Severe complications related to CABG procedures can also result from the 
sternotomy. Significant post-operative sternal infection usually requires 
reoperation and excision of the sternum and muscle flap. The rate of wound 
complications after sternotomy in a major study was 1.1% overall (72 patients 
out of 6,504), with 10 of those 72 dying before being discharged from the 
hospital. The patients with wound complications had a median length of 
hospital stay of 43 days, and triple the hospital costs of patients without 
such complications.
     
     CATHETER-BASED THERAPIES

     Catheter-based therapies, such as balloon angioplasty, atherectomy and 
coronary stenting, have become increasingly popular and effective over the 
last ten years. Balloon angioplasty is a procedure in which a balloon-tipped 
intravascular catheter is inserted into the femoral artery through a small 
incision in the upper thigh, is guided to the lesion (site of plaque) and 
then inflated and deflated several times to reshape the plaque and increase 
blood flow. Additional interventional devices for coronary artery disease 
include atherectomy devices (devices that cut or ablate and remove plaque 
from the arterial wall), laser catheter devices (devices that use laser 
energy to reduce plaque in arteries) and coronary stents (expandable metal 
frames that are positioned within the diseased area in the coronary artery to 
maintain the vessel opening). These treatments occur in a catheterization 
laboratory and are performed on a beating heart so they do not require a 
heart-lung machine. As a result, the length of stay and recuperation period 
are substantially less than those required with CABG. Currently, a common 
form of catheter-based treatment involves the use of balloon angioplasty 
followed by the placement of a coronary stent in the diseased artery. As a 
result of these minimally invasive approaches, patients are typically 
discharged within 24 to 48 hours and can return to a normal lifestyle within 
several days.
     
     While less invasive and traumatic than CABG, catheter-based therapies 
may not offer prolonged efficacy. Studies have indicated that within three to 
six months after a balloon angioplasty,


                                       5


between 25% and 45% of patients experience restenosis (a renarrowing of the 
treated coronary artery). In addition, 5% to 7% of coronary balloon 
angioplasty patients experience abrupt reclosure of the treated vessel, which 
may be caused in part by flaps or tears of plaque that occur in the course of 
such treatment. In patients with multi-vessel coronary artery disease, a 
randomized study has shown that within three years of receiving treatment, 
only 7% of patients receiving CABG surgery required reintervention while 40% 
of patients receiving balloon angioplasty required reintervention. Additional 
studies have confirmed that approximately 20% of balloon angioplasty patients 
with multi-vessel disease will undergo CABG surgery within one year of 
receiving balloon angioplasty. However, the efficacy of catheter-based 
treatments may be improving. Recent multi-center studies indicated that 
restenosis rates after treatment with stents can be reduced by approximately 
30% as compared to balloon angioplasty alone. Future advancements in stents 
or other catheter-based treatments may further reduce restenosis rates.
     
     The average cost of a balloon angioplasty procedure in the United States 
is approximately $15,000 or less than one-half of the average cost of CABG 
surgery. In a recent study, the cost of balloon angioplasty was equivalent to 
that of CABG three years after the procedure, primarily due to the expense of 
reintervention for the balloon angioplasty patient. In addition, the use of 
stenting greatly increases the cost of a catheter-based procedure. One study 
indicated that the average cost per procedure for elective stenting was 
approximately twice the cost of balloon angioplasty treatment without 
stenting (or nearly equal to the cost of CABG surgery).
     
THE MIDCAB PROCEDURE

     Recently, a new procedure known as Minimally Invasive Direct Coronary 
Artery Bypass ("MIDCAB") has been developed that applies the techniques of 
minimally invasive intervention to CABG surgery. The Company believes that 
this procedure will provide patients with minimally invasive advantages 
similar to those of catheter-based procedures and clinical benefits 
comparable to those of CABG procedures. The Company believes the MIDCAB 
procedure offers the following benefits:
     
     ELIMINATES HEART-LUNG MACHINE.  Surgery is performed upon the beating 
heart, eliminating the need for a heart-lung machine. The heart-lung machine 
is a major contributing factor to the post-operative complications of CABG, 
which include stroke, bleeding and respiratory complications.
     
     MINIMALLY INVASIVE.  Access to the heart is provided through a small 
incision called a mini-thoracotomy, eliminating the need for a sternotomy, in 
which a twelve inch incision is made by sawing through the sternum or 
breastbone and spreading the ribcage apart to expose the heart. The healing 
of the sternum adds significantly to the recovery time for a CABG procedure, 
even in procedures without complications.

     PROVIDES DIRECT ACCESS.  Placement of the mini-thoracotomy provides 
access to the heart and the internal mammary arteries, permitting grafts to 
be performed under the surgeon's direct vision without the need for 
endoscopic equipment.

     REDUCES COSTS.  Studies indicate that fewer complications result in 
shorter hospital stays (approximately two days), less recuperation time 
(approximately two weeks) and reduced patient trauma relative to CABG 
surgery. The Company believes that the MIDCAB procedure represents a 


                                       6


significant advancement in the delivery of coronary revascularization and 
will provide patients, payors and providers with a cost-effective alternative 
to existing interventional procedures.
     
     In the CTS MIDCAB procedure, the patient is placed under general 
anesthesia and a mini-thoracotomy is made just below the patient's breast, 
between the ribs. The procedure takes advantage of the fact that the heart 
and the arteries are located directly under the incision, unlike a 
conventional CABG procedure where the heart must be moved into position 
during the procedure. The LIMA Lift is inserted into the mini-thoracotomy and 
expanded to create an opening and offset the ribs. Under direct vision, 
without the need for endoscopic equipment, the surgeon then dissects the IMA 
from the chest wall. The IMA branches are gently exposed and are then clipped 
and cauterized. After the IMA is harvested to a satisfactory length the LIMA 
Lift is removed and the Access Platform is inserted into the chest opening. A 
small incision is then made in the pericardium (a fibrous, fluid filled sac 
that holds the heart in place in the chest cavity) and the coronary artery is 
exposed. The CTS MIDCAB procedure requires only a small pericardial incision, 
which allows the pericardium to continue to provide some support to the 
heart. The surgeon positions the Stabilizer at the grafting site isolating it 
and rendering it motionless. A small incision is made in coronary artery at 
the site of the grafting, and the IMA artery is grafted, under the surgeon's 
direct vision, onto the beating heart. After the grafting is complete, the 
pericardium and the chest are sewn shut and the procedure is complete. 
     
     Despite the potential benefits of the MIDCAB procedure for the treatment 
of coronary heart disease, it is currently performed by only a small number 
of cardiothoracic surgeons. The Company believes that most cardiothoracic 
surgeons have been reluctant to attempt the MIDCAB procedure because of, 
among other things, the difficulties of performing surgery on the beating 
heart. Of the procedures performed to date, the vast majority have been 
performed on a single artery, typically the LAD or, in substantially fewer 
instances, the RCA, and an extremely limited number have been performed on 
the circumflex artery. The LAD is the primary blood supply to the heart and 
supplies a large amount of the myocardium. Studies indicate that restoring 
blood flow to the LAD is the single most important factor in predicting 
long-term, event-free survival. As a result, the Company believes that many 
of the patients currently undergoing CABG surgery or catheter-based 
treatments are candidates for the MIDCAB procedure. A significant percentage 
of CABG procedures are performed on multiple vessels. To date, multiple 
vessel MIDCAB procedures have only been performed on an extremely limited 
basis, and there can be no assurance that the MIDCAB procedure will be 
effectively utilized for multiple bypasses on a more frequent basis. The 
Company is unable to predict how quickly, if at all, the MIDCAB procedure 
will be adopted by the medical community or, if it is adopted, the number of 
MIDCAB procedures that will be performed.
     
     Although the Company believes that the CTS MIDCAB procedure has 
significant advantages over competing procedures, broad-based clinical 
adoption of the procedure will not occur until physicians determine that the 
procedure is an attractive alternative to current treatments for coronary 
artery disease. The Company believes that physician endorsements will be 
essential for clinical adoption of this procedure, and there can be no 
assurance that any such endorsements will be obtained in a timely manner, if 
at all. Clinical adoption will also depend upon the Company's ability to 
facilitate training of cardiothoracic surgeons to perform minimally invasive 
bypass surgery on a beating heart, and the willingness of such surgeons to 
perform such a procedure. Patient acceptance of the procedure will depend in 
part upon physician recommendations as well as other factors, including the 
degree of invasiveness, the effectiveness of the procedure and rate and 
severity of complications associated with the procedure as compared to other 
treatments. Even if the clinical efficacy of the MIDCAB procedure is 
established, physicians may elect not to recommend the procedure unless 
acceptable reimbursement 

                                       7


from health care payors is available. Health care payor acceptance may 
require evidence of the cost effectiveness of the MIDCAB procedure as 
compared to other currently available treatments. There can be no assurance 
that the MIDCAB procedure will gain clinical adoption. Failure of the MIDCAB 
procedure to achieve significant clinical adoption would have a material 
adverse effect on the Company's business, financial condition and results of 
operations.
     
THE CTS MIDCAB SYSTEM

     The Company's MIDCAB System is comprised of proprietary disposable 
surgical instruments designed to facilitate the MIDCAB procedure. The Company 
expects to accelerate the adoption of the MIDCAB procedure by marketing the 
CTS MIDCAB System that enables the majority of cardiothoracic surgeons, using 
their existing skills coupled with Company sponsored training, to perform the 
MIDCAB procedure. The CTS MIDCAB System is designed to provide the necessary 
access to the chest cavity, simplify the harvesting of the internal mammary 
artery, and optimize the conditions necessary for a quality graft to be 
performed on a beating heart. Key components of the CTS MIDCAB System include:

     THE ACCESS PLATFORM is designed to maximize access to the chest cavity 
through a mini-thoracotomy. The Access Platform creates an operating window 
into the chest cavity by smoothly retracting tissue and spreading the ribs 
for optimal exposure of the heart and arteries with minimal patient trauma.

     THE STABILIZER incorporates feet that are attached by a radial arm to 
the Access Platform. The Stabilizer is designed to apply slight pressure to 
the myocardium and thereby isolate the diseased artery, minimize the motion 
of the beating heart and permit the surgeon to complete the graft.
     
     THE LIMA-LIFT is a unique spreading system that offsets the ribs to 
provide a window into the chest cavity so the surgeon can harvest the IMA 
without using an endoscope.
     
     THE LIMA-LOOP enables a surgeon to reach into the chest to help isolate 
the IMA for harvest.
     
     The CTS MIDCAB System  is expected to account for the great majority of 
the Company's revenue for the foreseeable future. The Company has sold very 
little product in 1996, and there can be no assurance that the Company is 
capable of manufacturing the CTS MIDCAB System in commercial quantities at 
acceptable costs.  Nor can there be any assurance that demand for the CTS 
MIDCAB System will be sufficient to allow profitable operations. Failure of 
the CTS MIDCAB System to be successfully commercialized would have a material 
adverse effect on the Company's business, financial condition and results of 
operations.
     
SALES, MARKETING AND DISTRIBUTION

     The Company markets its products principally to cardiac surgeons.  The
Company's initial marketing strategy is to generate broad based market
acceptance of the MIDCAB procedure and the CTS MIDCAB System by sponsoring
educational programs, surgeon training programs and cultivating relationships
with opinion leaders in cardiac surgery. The Company has established a
Scientific Advisory Board comprised of cardiothoracic surgery opinion leaders,
prominent surgeons and leading interventional cardiologists. The members of the
Scientific Advisory Board participates in


                                       8


Company-sponsored educational and training sessions, thereby encouraging 
acceptance of the MIDCAB procedure among cardiothoracic surgeons and the 
integration of the MIDCAB procedure into their hospital and surgical 
practices.
     
     The Company currently has a direct sales force of eight people in the 
United States which are supported by 6 clinical specialists. In December 1996 
the Company established CardioThoracic Systems, GmBH, a wholly owned 
subsidiary, in Dusseldorf Germany in order to build a direct sales and 
marketing organization for Germany.  In other markets, the Company will be 
selling its products primarily through distributors. 

CUSTOMER TRAINING 

     The Company believes that its Comprehensive Optimal Revascularization 
(COR) training and education program plays a important role in the adoption 
of the CTS MIDCAB procedure.  The Company has entered into agreements with 
three cardiac surgical centers in the United States and three in Europe to 
become COR Institutes.  The COR Institutes host a two-day, hands-on training 
workshop presented by recognized authorities in minimally invasive cardiac 
surgery.  The COR program teaches surgical teams key aspects of how to 
perform a MIDCAB procedure using the CTS MIDCAB System.  When the surgical 
team returns to their own hospital the Company's clinical specialist will 
provide additional training as required.  In 1997 the Company plans on 
establishing regional  COR  training programs in major metropolitan areas 
throughout the United States at non-hospital sites in order to increase the 
Company's ability to train surgeons.

RESEARCH AND DEVELOPMENT

     The Company is directing its research efforts toward development of 
proprietary surgical instruments and systems for cardiothoracic minimally 
invasive procedures, including coronary bypass, saphenous vein harvesting and 
valve repair and reconstruction. In addition, the Company is researching 
other methods of vessel attachment and stabilization of the beating heart. 
Most of the products under development will require regulatory clearance or 
approval prior to commercialization.  As of December 31, 1996, the Company's 
research and development staff consisted of 28 full-time engineers and 
technicians who have substantial experience in the development of medical 
devices, including expertise in the application of mechanical and electrical 
design principles to devices for cardiovascular applications. In addition, 
several of the Company's scientific advisors have prominent roles in 
directing the technical and medical research and development efforts at the 
Company.  Research and development expenses for the year ended December 31, 
1996 was $11.5 million.
     
MANUFACTURING

     To date, the Company's manufacturing activities have consisted only of 
building small quantities of the CTS MIDCAB System. As a result, the Company 
has no experience manufacturing the CTS MIDCAB System in the volumes that 
would be necessary for the Company to achieve significant commercial sales. 
There can be no assurance that reliable, high-volume manufacturing can be 
established or maintained at commercially reasonable costs.
     
     The Company's manufacturing facilities will be subject to GMP regulations,
international quality standards and other regulatory requirements. Difficulties
encountered by the Company in


                                       9


manufacturing scale-up or failure by the Company to implement and maintain 
its facilities in accordance with GMP regulations, international quality 
standards or other regulatory requirements could entail a delay or 
termination of production, which could have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     The Company purchases most of the components for the CTS MIDCAB System 
from various independent suppliers that are either standard components or are 
built or molded to the Company's proprietary specifications.  In addition, 
the Company contracts with third parties for the performance of certain 
processes involved in the manufacturing cycle such as painting and finished 
product sterilization. Some of these components and processes may only be 
available from single-source vendors. Any prolonged supply interruption or 
yield problems experienced by the Company due to a single-source vendor could 
have a material adverse effect on the Company's ability to manufacture its 
products under development until a new source of supply is qualified. As the 
Company increases production, it may from time to time experience lower than 
anticipated yields or production constraints, resulting in delayed product 
shipments, which could adversely affect the Company's business, financial 
condition and results of operations.

PATENTS AND PROPRIETARY RIGHTS

     The Company's ability to compete effectively will depend in part on its 
ability to develop and maintain proprietary aspects of its technology. The 
Company owns two issued United States patents. The issued patents do not 
contain any claims that protect the CTS MIDCAB System. The Company is the 
licensee of a United States patent application for bipolar electrosurgical 
scissors that may be used in the IMA Harvester and the Saphenous Vein 
Harvesting System. The Company has filed twenty-one U.S. patent applications 
and various corresponding foreign patent applications. There can be no 
assurance that any issued patents or any patents which may be issued as a 
result of the Company's licensed patent application or United States and 
international patent applications will provide any competitive advantages for 
the Company's products or that they will not be successfully challenged, 
invalidated or circumvented in the future. In addition, there can be no 
assurance that competitors, many of which have substantial resources and have 
made substantial investments in competing technologies, will not seek to 
apply for and obtain patents that will prevent, limit or interfere with the 
Company's ability to make, use and sell its products either in the United 
States or in international markets.
     
     The medical device industry has been characterized by extensive 
litigation regarding patents and other intellectual property rights, and 
companies in the medical device industry have employed intellectual property 
litigation to gain a competitive advantage. There can be no assurance that 
the Company will not become subject to patent infringement claims or 
litigation or subject to interference proceedings declared by the United 
States Patent and Trademark Office ("USPTO") to determine the priority of 
inventions. The defense and prosecution of intellectual property suits, USPTO 
interference proceedings and related legal and administrative proceedings are 
both costly and time-consuming. Litigation may be necessary to enforce 
patents issued to the Company, to protect trade secrets or know-how owned by 
the Company or to determine the enforceability, scope and validity of the 
proprietary rights of others. Any litigation or interference proceedings will 
result in substantial expense to the Company and significant diversion of 
effort by the Company's technical and management personnel. An adverse 
determination in litigation or interference proceedings to which the Company 
may become a party, including any litigation that may arise against the 
Company as described in "Legal Proceedings" below, could subject the Company 
to significant liabilities to third parties or require the Company to seek 
licenses from third parties or prevent the Company from selling its products in


                                       10


certain markets, or at all. Although patent and intellectual property 
disputes regarding medical devices have often been settled through licensing 
or similar arrangements, costs associated with such arrangements may be 
substantial and could include ongoing royalties. Furthermore, there can be no 
assurance that the necessary licenses would be available to the Company on 
satisfactory terms, if at all. Adverse determinations in a judicial or 
administrative proceeding or failure to obtain necessary licenses could 
prevent the Company from manufacturing and selling its products, which would 
have a material adverse effect on the Company's business, financial condition 
and results of operations.
     
     Congress enacted legislation, which became effective October 1, 1996, 
that places certain restrictions on the ability of medical device 
manufacturers to enforce certain patent claims, relating to surgical and 
medical methods, against medical practitioners. Such limitation in the 
enforceability of patent claims, relating to medical and surgical methods, 
against medical practitioners could have a material adverse effect on the 
Company's ability to protect its proprietary methods and procedures against 
medical practitioners.
     
     In addition to patents, the Company relies on trade secrets and 
proprietary know-how, which it seeks to protect, in part, through 
confidentiality and proprietary information agreements. There can be no 
assurance that such confidentiality or proprietary information agreements 
will not be breached, that the Company would have adequate remedies for any 
breach, or that the Company's trade secrets will not otherwise become known 
to or be independently developed by competitors.
     
COMPETITION

     The Company believes that the principal competitive factors in the 
market for treatment of cardiovascular disease are safety, efficacy, ease of 
use, reliability and cost effectiveness. The Company believes that the MIDCAB 
procedure performed with the CTS MIDCAB System will be substantially less 
costly than highly-invasive, traditional surgical procedures and may 
ultimately replace these procedures in some applications. The Company 
believes that the CTS MIDCAB System will enable surgeons to perform coronary 
bypass surgery less invasively, in a shorter period of time and with reduced 
patient trauma, resulting in reduced recuperation time in the ICU, shorter 
hospital stays and faster recovery, as well as lower complication rates. As a 
result, the Company believes that the CTS MIDCAB System will compete 
favorably with respect to each of these factors, although no assurance can be 
given that it will compete favorably.
     
     The medical device industry and the market for treatment of 
cardiovascular disease, in particular, are characterized by rapidly evolving 
technology and intense competition. A number of competitors including Johnson 
& Johnson, Boston Scientific Corporation, Cordis Corporation, Guidant 
Corporation and Medtronic, Inc. are currently marketing stents, catheters, 
lasers, drugs and other less invasive means of treating cardiovascular 
disease. Many of these less invasive treatments and CABG surgery are widely 
accepted in the medical community and have a long history of safe and 
effective use. Many of the Company's competitors have substantially greater 
capital resources, name recognition and expertise in and resources devoted to 
research and development, manufacturing and marketing and obtaining 
regulatory clearances or approvals. Furthermore, competition in the emerging 
market for minimally invasive cardiothoracic surgery is expected to be 
intense and to increase. Heartport, Inc., Medtronic, Inc., Research Medical 
Inc. and United States Surgical Corp. are marketing or have announced that 
they are developing products to be used in minimally invasive coronary 
procedures. There can be no assurance that the MIDCAB procedure will replace 
any current treatments. Additionally, even if it is widely adopted, there can 
be no assurance that the Company's competitors


                                       11


will not succeed in developing alternative procedures and technologies, 
competing devices to perform the same procedure or therapeutic drugs that are 
more effective than the Company's products or that render the Company's 
products or technologies obsolete or not competitive. In addition, there can 
be no assurance that existing products for other surgical uses will not be 
used in MIDCAB procedures. Such competition could have a material adverse 
effect on the Company's business, financial condition and results of 
operations.
     
GOVERNMENT REGULATION

     The medical devices to be marketed and manufactured by the Company are 
subject to extensive regulation by the FDA, and, in some instances, by 
foreign governments. Pursuant to the Federal Food, Drug, and Cosmetic Act of 
1976, as amended, and the regulations promulgated thereunder (the "FDC Act"), 
the FDA regulates the clinical testing, manufacture, labeling, distribution, 
and promotion of medical devices. Noncompliance with applicable requirements 
can result in, among other things, fines, injunctions, civil penalties, 
recall or seizure of products, total or partial suspension of production, 
failure of the government to grant premarket clearance or premarket approval 
for devices, withdrawal of marketing approvals, and criminal prosecution. The 
FDA also has the authority to request repair, replacement or refund of the 
cost of any device manufactured or distributed by the Company.
     
     In the United States, medical devices are classified into three classes 
(Class I, II or III), on the basis of the controls deemed necessary by the 
FDA to reasonably assure their safety and effectiveness. Under FDA 
regulations, Class I devices are subject to general controls (for example, 
labeling, premarket notification and adherence to good manufacturing 
practices ("GMPs")) and Class II devices are subject to general and special 
controls (for example, performance standards, postmarket surveillance, 
patient registries and FDA guidelines). Generally, Class III devices are 
those which must receive premarket approval by the FDA to ensure their safety 
and effectiveness (for example, life-sustaining, life-supporting and 
implantable devices, or new devices which have not been found substantially 
equivalent to legally marketed devices).
     
     Before a new device can be introduced into the United States market, the 
manufacturer must generally obtain marketing clearance through either a 
510(k) premarket notification or a premarket approval ("PMA") application. A 
510(k) clearance will be granted if the submitted information establishes 
that the proposed device is "substantially equivalent" to a legally marketed 
Class I or II medical device, or to a Class III medical device for which the 
FDA has not called for a PMA. The FDA may determine that a proposed device is 
not substantially equivalent to a legally marketed device, or that additional 
information or data are needed before a substantial equivalence determination 
can be made. A request for additional data may require that clinical studies 
of the device's safety and efficacy be performed. 
     
     Commercial distribution of a device for which a 510(k) premarket 
notification is required can begin only after the FDA issues an order finding 
the device to be "substantially equivalent" to a predicate device. The FDA 
has recently been requiring a more rigorous demonstration of substantial 
equivalence than in the past. It generally takes from four to twelve months 
from the date of submission to obtain a 510(k) clearance, but it may take 
longer. The FDA may determine that a proposed device is not substantially 
equivalent to a legally marketed device, or that additional information is 
needed before a substantial equivalence determination can be made.


                                       12


     A "not substantially equivalent" determination, or a request for 
additional information, could delay the market introduction of new products 
that fall into this category and could have a materially adverse effect on 
the Company's business, financial condition and results of operations. For 
any of the Company's products that were cleared through the 510(k) process, 
modifications or enhancements that could significantly affect the safety or 
efficacy of the device or that constitute a major change to the intended use 
of the device will require new 510(k) submissions.
     
     A PMA application must be filed if a proposed device is not 
substantially equivalent to a legally marketed Class I or Class II device, or 
if it is a Class III device for which the FDA has called for PMAs. A PMA 
application must be supported by valid scientific evidence which typically 
includes extensive data, including human clinical trial data to demonstrate 
the safety and effectiveness of the device. The PMA application must also 
contain the results of all relevant bench tests, laboratory and animal 
studies, a complete description of the device and its components, and a 
detailed description of the methods, facilities and controls used to 
manufacture the device. In addition, the submission must include the proposed 
labeling, advertising literature and training methods (if required).
     
     Upon receipt of a PMA application, the FDA makes a threshold 
determination as to whether the application is sufficiently complete to 
permit a substantive review. If the FDA determines that the PMA application 
is sufficiently complete to permit a substantive review, the FDA will accept 
the application for filing. Once the submission is accepted for filing, the 
FDA begins an in-depth review of the PMA. An FDA review of a PMA application 
generally takes one to two years from the date the PMA application is 
accepted for filing, but may take significantly longer. The review time is 
often significantly extended by the FDA asking for more information or 
clarification of information already provided in the submission. During the 
review period, an advisory committee, typically a panel of clinicians, will 
likely be convened to review and evaluate the application and provide 
recommendations to the FDA as to whether the device should be approved. The 
FDA is not bound by the recommendations of the advisory panel. Toward the end 
of the PMA review process, the FDA generally will conduct an inspection of 
the manufacturer's facilities to ensure that the facilities are in compliance 
with applicable GMP requirements.
     
     If the FDA's evaluations of both the PMA application and the 
manufacturing facilities are favorable, the FDA will either issue an approval 
letter or an approvable letter, which usually contains a number of conditions 
that must be met in order to secure final approval of the PMA. When and if 
those conditions have been fulfilled to the satisfaction of the FDA, the 
agency will issue a PMA approval letter, authorizing commercial marketing of 
the device for certain indications. If the FDA's evaluation of the PMA 
application or manufacturing facilities are not favorable, the FDA will delay 
approval of the PMA application or issue a "not approvable letter." The FDA 
may also determine that additional clinical trials are necessary, in which 
case PMA approval may be delayed for several years while additional clinical 
trials are conducted and submitted in an amendment to the PMA. The PMA 
process is expensive, uncertain and lengthy and a number of devices for which 
FDA approval has been sought by other companies have never been approved for 
marketing. Modifications to a device that is the subject of an approved PMA, 
its labeling, or manufacturing process may require approval by the FDA of PMA 
supplements or new PMAs. Supplements to a PMA often require the submission of 
the same type of information required for an initial PMA, except that the 
supplement is generally limited to that information needed to support the 
proposed change from the product covered by the original PMA.
     
     If human clinical trials of a device are required in connection with either
a 510(k) premarket notification or a PMA, and the device presents a "significant
risk," the sponsor of the trial (usually the


                                       13


manufacturer or the distributor of the device) is required to file an 
investigational device exemption ("IDE") application prior to commencing 
human clinical trials. The IDE application must be supported by data, 
typically including the results of animal and laboratory testing. If the IDE 
application is reviewed and approved by the FDA and one or more appropriate 
Institutional Review Boards ("IRBs"), human clinical trials may begin at a 
specific number of investigational sites with a specific number of patients, 
as approved by the FDA. If the device presents a "nonsignificant risk" to the 
patient, a sponsor may begin the clinical trial after obtaining approval for 
the study by one or more appropriate IRBs, but not the FDA. Sponsors of 
clinical trials are permitted to sell those devices distributed in the course 
of the study provided such compensation does not exceed recovery of the costs 
of manufacture, research, development and handling. An IDE supplement must be 
submitted to and approved by the FDA before a sponsor or an investigator may 
make a change to the investigational plan that may affect its scientific 
soundness or the rights, safety or welfare of human subjects.
     
     Any products manufactured or distributed by the Company pursuant to the 
FDA clearances or approvals are subject to pervasive and continuing 
regulation by the FDA, including record keeping requirements and reporting of 
adverse experiences with the use of the device. Device manufacturers are 
required to register their establishments and list their devices with the FDA 
and certain state agencies, and are subject to periodic inspections by the 
FDA and certain state agencies. The FDC Act requires devices to be 
manufactured in accordance with GMP regulations which impose certain 
procedural and documentation requirements upon the Company with respect to 
manufacturing and quality assurance activities. The FDA has recently 
finalized changes to the GMP regulations which will likely increase the cost 
of complying with GMP requirements.
     
     Labeling and promotion activities are subject to scrutiny by the FDA and 
in certain instances, by the Federal Trade Commission. The FDA actively 
enforces regulations prohibiting marketing of products for unapproved uses. 
The Company and its products  are also subject to a variety of state laws and 
regulations in those states or localities where its products will be 
marketed. Any applicable state or local regulations may hinder the Company's 
ability to market its products in those states or localities. Manufacturers 
are also subject to numerous federal, state and local laws relating to such 
matters as safe working conditions, manufacturing practices, environmental 
protection, fire hazard control and disposal of hazardous or potentially 
hazardous substances. There can be no assurance that the Company will not be 
required to incur significant costs to comply with such laws and regulations 
now or in the future or that such laws or regulations will not have a 
material adverse effect upon the Company's ability to do business.
     
     Exports of products that have market clearance from the FDA do not 
require export approval. However, some foreign countries require 
manufacturers to provide an FDA certificate for products for export ("CPE") 
which requires the device manufacturer to certify to the FDA that the product 
has been granted premarket clearance in the United States and that the 
manufacturing facilities appeared to be in compliance with GMPs at the time 
of the last GMP inspection. The FDA will refuse to issue a CPE if significant 
outstanding GMP violations exist.
     
     Exports of products subject to the 510(k) notification requirements, but 
not yet cleared to market, are permitted without FDA export approval provided 
certain requirements are met. Unapproved products subject to the PMA 
requirements must be approved by FDA for export. To obtain FDA export 
approval certain requirements must be met and information must be provided to 
the FDA, including documentation demonstrating that the product is approved 
for import into the country to which it is to be exported and, in some 
instances, safety data from animal or human studies. There


                                       14


can be no assurance that the FDA will grant export approval when such 
approval is necessary, or that countries to which the devices are to be 
exported will approve the devices for import. Failure of the Company to 
obtain CPEs, meet the FDA's export requirements, or obtain FDA export 
approval when required to do so, could have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     The introduction of the Company's products in foreign markets will also 
subject the Company to foreign regulatory clearances, registrations or 
approvals which may impose additional substantial costs and burdens. 
International sales of medical devices are subject to the regulatory 
requirements of each country. The regulatory review process varies from 
country to country. Many countries also impose product standards, packaging 
requirements, labeling requirements and import restrictions on devices. In 
addition, each country has its own tariff regulations, duties and tax 
requirements. The approval by the FDA and foreign government authorities is 
unpredictable and uncertain, and no assurance can be given that the necessary 
clearances, registrations or approvals will be granted on a timely basis or 
at all. Delays in receipt of, or a failure to receive, such clearances, 
registrations or approvals, or the loss of any previously received, 
clearances, registrations or approvals, could have a material adverse effect 
on the business, financial condition and results of operations of the Company.
     
     The European Union has promulgated rules that require that medical 
products receive the right to affix the CE mark by mid-1998. The CE mark is 
an international symbol of adherence to quality assurance standards and 
compliance with applicable European medical device directives. In order to 
obtain the right to affix the CE mark to its current and future products, the 
Company will need to obtain certification that its processes meet ISO 9000 
quality standards. Failure to receive the right to affix the CE mark will 
prohibit the Company from selling its current or future products in member 
countries of the European Union after mid-1998. In January 1997 the Company 
received ISO 9001 certification and CE Mark approval for the CTS MIDCAB 
System.
     
     In May 1996 the Company was notified by the FDA that it is exempted from 
filing a premarket notification for the CTS Access Platform and the 
Stabilizer. In September 1996 the Company filed 510(k) premarket 
notifications for clearance to market additional components of the CTS MIDCAB 
System and the bipolar electrosurgical scissors.  In January 1997 the Company 
received clearance to market the bipolar electrosurgical scissors.  The 
Company intends to seek clearance to market additional components of the 
Saphenous Vein Harvesting System through 510(k) premarket notifications. 
There can be no assurance that the FDA will act favorably or quickly on the 
Company's 510(k) submissions, and significant difficulties and costs may be 
encountered by the Company in its efforts to obtain FDA clearance that could 
delay or preclude the Company from selling its potential products in the 
United States. Failure to receive, or delays in the receipt of FDA clearances 
or approvals could have a material adverse effect on the Company's business, 
financial condition and results of operations.
      
      The Company's products are subject to continued and pervasive 
regulation by the FDA and other foreign and domestic regulatory authorities. 
Changes in existing requirements or adoption of new requirements or policies 
could adversely affect the ability of the Company to comply with regulatory 
requirements. Failure to comply with regulatory requirements could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. There can be no assurance that the Company will not be 
required to incur significant costs to comply with laws and regulations in 
the future or that laws or regulations will not have a material adverse 
effect upon the Company's business, financial condition or results of 
operations.


                                       15


THIRD-PARTY REIMBURSEMENT

     In the United States, health care providers, such as hospitals and 
physicians, that purchase medical devices, such as the Company's products 
under development, generally rely on third-party payors, principally 
Medicare, Medicaid and private health insurance plans, to reimburse all or 
part of the cost of the procedure in which the medical device is being used. 
Reimbursement for cardiovascular surgery, including CABG surgery, using 
devices that have received FDA approval has generally been available in the 
United States. In addition, certain health care providers are moving toward a 
managed care system in which such providers contract to provide comprehensive 
health care for a fixed cost per person. Although the Company believes that 
the cost of a MIDCAB procedure performed with the CTS MIDCAB System will be 
reimbursable under the current diagnosis-related group ("DRG") system, the 
Company is unable to predict what changes will be made in the reimbursement 
methods utilized by third-party health care payors. The Company anticipates 
that in a prospective payment system, such as the DRG system utilized by 
Medicare, and in many managed care systems used by private health care 
payors, the cost of the Company's products would be incorporated into the 
overall cost of the procedure and that there would be no separate, additional 
reimbursement for the Company's products. The Company anticipates that 
hospital administrators and physicians would justify the use of the Company's 
products by the attendant cost savings and clinical benefits that the Company 
believes would be derived from the use of its products. However, there can be 
no assurance that this will be the case. Furthermore, the Company could be 
adversely affected by changes in reimbursement policies of government or 
private health care payors, particularly to the extent any such changes 
affect reimbursement for the procedure in which the Company's products are 
intended to be used. Failure by physicians, hospitals and other potential 
users of the Company's products to obtain sufficient reimbursement from 
health care payors for the procedure in which the Company's products are 
intended to be used or adverse changes in government and private third-party 
payors' policies toward reimbursement for such procedures could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     If the Company obtains the necessary foreign regulatory registrations or 
approvals, market acceptance of the Company's products in international 
markets would be dependent, in part, upon the availability of reimbursement 
within prevailing health care payment systems. Reimbursement and health care 
payment systems in international markets vary significantly by country, and 
include both government sponsored health care and private insurance. The 
Company intends to seek international reimbursement approvals, although there 
can be no assurance that any such approvals will be obtained in a timely 
manner, if at all, and failure to receive international reimbursement 
approvals could have a material adverse effect on market acceptance of the 
Company's products in the international markets in which such approvals are 
sought.
     
PRODUCT LIABILITY AND INSURANCE

     The development, manufacture and sale of medical products entail 
significant risk of product liability claims and product recalls. The 
Company's current product liability insurance coverage limits are $3,000,000 
per occurrence and $3,000,000 in the aggregate, and there can be no assurance 
that such coverage limits are adequate to protect the Company from any 
liabilities it might incur in connection with the development, manufacture 
and sale of its products. In addition, the Company may require increased 
product liability coverage as product sales increase.   Product liability 
insurance is expensive and in the future may not be available to the Company 
on acceptable terms, if at all. A successful


                                       16


product liability claim or series of claims brought against the Company in 
excess of its insurance coverage or a product recall could have a material 
adverse effect on the Company's business, financial condition and results of 
operations.
     
EMPLOYEES

     As of December 31, 1996, the Company had 71 full-time employees. 
Twenty-eight persons are engaged in research and development and regulatory 
affairs activities, Nineteen persons are engaged in sales and marketing 
activities, fourteen persons are engaged in manufacturing and quality 
assurance and ten persons are engaged in finance and administration. No 
employees are covered by collective bargaining agreements, and the Company 
believes it maintains good relations with its employees.
     
OTHER FACTORS 

     This annual report on Form 10-K contains forward-looking statements 
within the meaning of Section 27A of the Securities Act of 1933 and Section 
21E of the Securities and Exchange Act of 1934.  The Company's future results 
could differ materially from those anticipated by such forward-looking 
statements as a result of certain factors including those set forth in the 
following factors and elsewhere in this annual report on Form 10-K.
     
     LIMITED OPERATING HISTORY; HISTORY OF LOSSES AND EXPECTATION OF FUTURE 
LOSSES.  The Company has a limited operating history upon which evaluation of 
its prospects can be made. Such prospects must be considered in light of the 
substantial risks, expenses and difficulties encountered by entrants into the 
medical device industry, which is characterized by an increasing number of 
participants, intense competition and a high failure rate. To date, the 
Company has engaged primarily in organizational and research and product 
development efforts, and a number of the Company's key management and 
technical personnel have only recently joined the Company.  The Company has 
only recently generated revenues and has very limited experience in 
manufacturing, marketing or selling the CTS MIDCAB System. The Company has 
experienced operating losses since its inception, and, as of December 31, 
1996, the Company had an accumulated deficit of approximately $17,075,000. 
The development and commercialization of the Company's products will require 
substantial development, regulatory, sales and marketing, manufacturing and 
other expenditures. The Company expects its operating losses to continue at 
least through 1997 as it continues to expend substantial resources to 
continue development of the Company's products, obtain additional regulatory 
clearances or approvals, build its marketing, sales, manufacturing and 
finance organizations and conduct further research and development. There can 
be no assurance that the Company's products will ever gain commercial 
acceptance or that the Company will ever generate revenues or achieve 
profitability.

     UNCERTAINTY OF CLINICAL ADOPTION OF MIDCAB PROCEDURE.  The Company's CTS 
MIDCAB System is designed to enable the majority of cardiothoracic surgeons, 
using their existing skills coupled with Company sponsored training, to 
perform the Minimally Invasive Direct Coronary Artery Bypass ("MIDCAB") 
procedure. Accordingly, the Company's success is dependent upon acceptance of 
the MIDCAB procedure by the medical community as a reliable, safe and cost 
effective alternative to existing treatments for revascularizing blocked 
coronary arteries. To date, the MIDCAB procedure has only been performed on a 
limited basis by a small number of highly skilled cardiothoracic surgeons. Of 
the procedures performed to date, the vast majority have been performed on a 
single artery, typically the left anterior descending artery ("LAD") or, in 
substantially fewer instances, the right coronary artery ("RCA"), and an 
extremely limited number have been performed on the circumflex artery. A 


                                       17


significant percentage of coronary artery bypass graft ("CABG") procedures 
are performed on multiple vessels. To date, multiple vessel MIDCAB procedures 
have only been performed on an extremely limited basis, and there can be no 
assurance that the MIDCAB procedure will be effectively utilized for multiple 
bypasses on a more frequent basis. The Company is unable to predict how 
quickly, if at all, the MIDCAB procedure will be adopted by the medical 
community or, if it is adopted, the number of MIDCAB procedures that will be 
performed. The medical conditions that can be treated with the MIDCAB 
procedure can also be treated by widely accepted surgical procedures such as 
CABG surgery and catheter-based treatments, including balloon angioplasty, 
atherectomy and coronary stenting. Broad-based clinical adoption of the 
MIDCAB procedure will not occur until physicians determine that the procedure 
is an attractive alternative to current treatments for coronary artery 
disease. The Company believes that physician endorsements will be essential 
for clinical adoption of this procedure, and there can be no assurance that 
any such endorsements will be obtained in a timely manner, if at all. 
Clinical adoption will also depend upon the Company's ability to facilitate 
training of cardiothoracic surgeons to perform minimally invasive bypass 
surgery on a beating heart, and the willingness of such surgeons to perform 
such a procedure. Patient acceptance of the procedure will depend in part 
upon physician recommendations as well as other factors, including the degree 
of invasiveness, the effectiveness of the procedure and rate and severity of 
complications associated with the procedure as compared to other treatments. 
Even if the clinical efficacy of the MIDCAB procedure is established, 
physicians may elect not to recommend the procedure unless acceptable 
reimbursement from health care payors is available. Health care payor 
acceptance may require evidence of the cost effectiveness of the MIDCAB 
procedure as compared to other currently available treatments. There can be 
no assurance that the MIDCAB procedure will gain clinical adoption. Failure 
of the MIDCAB procedure to achieve significant clinical adoption would have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     DEPENDENCE ON THE MIDCAB SYSTEM; UNCERTAINTY OF MARKET ACCEPTANCE OF THE 
MIDCAB SYSTEM.  The CTS MIDCAB System is expected to account for the great 
majority of the Company's revenues for the foreseeable future. The Company 
has only recently commenced sales of  the CTS MIDCAB System, and there can be 
no assurance that market acceptance and demand for the CTS MIDCAB System will 
be sufficient to allow profitable operations. Failure of the CTS MIDCAB 
System to be successfully commercialized would have a material adverse effect 
on the Company's business, financial condition and results of operations.
     
     LACK OF REGULATORY APPROVALS.  The design, manufacturing, labeling, 
distribution and marketing of certain components of the CTS MIDCAB System and 
the Saphenous Vein Harvesting System will be subject to extensive and 
rigorous government regulation in the United States and certain other 
countries where the process of obtaining and maintaining required regulatory 
clearance or approvals is lengthy, expensive and uncertain. In order for the 
Company to market certain of its products under development in the United 
States, the Company must obtain clearance or approval from the United States 
Food and Drug Administration ("FDA"). The Company intends to seek clearance 
to market additional components of the CTS MIDCAB System and the bipolar 
electrosurgical scissors through a 510(k) premarket notification. The Company 
has been notified by the FDA that it is exempted from filing a premarket 
notification for the CTS Access Platform and the Stabilizer and is allowed to 
market these products in the United States. In September 1996 the Company 
filed 510(k) premarket notifications for clearance to market additional 
components of the CTS MIDCAB System and the bipolar scissors. In January 1997 
the Company received clearance from the FDA to market the bipolar 
electrosurgical scissors. There can be no assurance that the FDA will act 
favorably or quickly on the Company's remaining or future 510(k) submissions, 
or that significant difficulties and costs will not be


                                       18


encountered by the Company in its efforts to obtain FDA clearance or 
approval. Any such difficulties could delay or preclude obtaining regulatory 
clearance or approval. In addition, there can be no assurance that the FDA 
will not impose strict labeling or other requirements as a condition of its 
510(k) clearance, any of which could limit the Company's ability to market 
its products. Further, if the Company wishes to modify a product after FDA 
clearance of a 510(k) premarket notification or approval of a PMA, including 
changes in indications or other modifications that could affect safety and 
efficacy, additional clearances or approvals will be required from the FDA. 
Failure to receive, or delays in receipt of, FDA clearances or approvals, 
including delays resulting from an FDA request for clinical trials or 
additional data as a prerequisite to clearance or approval, or any FDA 
conditions that limit the ability of the Company to market its products under 
development, could have a material adverse effect on the Company's business, 
financial condition and results of operations.
     
     In order for the Company to market its products in Europe and certain 
other international jurisdictions, the Company and its distributors and 
agents must obtain required regulatory registrations or approvals and 
otherwise comply with extensive regulations regarding safety, efficacy and 
quality. These regulations, including the requirements for registrations or 
approvals and the time required for regulatory review, vary from country to 
country. There can be no assurance that the Company will obtain regulatory 
registrations or approvals in such countries or that it will not be required 
to incur significant costs in obtaining or maintaining its foreign regulatory 
registrations or approvals. Delays in receipt of registrations or approvals 
to market the Company's products, failure to receive these registrations or 
approvals, or future loss of previously received registrations or approvals 
could have a material adverse effect on the Company's business, financial 
condition and results of operations.
     
     The European Union has promulgated rules that require that medical 
products receive by mid-1998 the right to affix the CE mark, an international 
symbol of adherence to quality assurance standards and compliance with 
applicable European medical device directives. In order to obtain the right 
to affix the CE mark to its products under development, the Company will need 
to obtain certification that its processes meet ISO 9000 quality standards.  
In January 1997 the Company received ISO 9001 certification and CE Mark 
approval for the CTS MIDCAB System.
     
     CONTINUING GOVERNMENT REGULATION.  Regulatory clearances or approvals, 
if granted, may include significant limitations on the indicated uses for 
which the products may be marketed. FDA enforcement policy strictly prohibits 
the marketing of FDA cleared or approved medical devices for unapproved uses. 
In addition, the Company's manufacturing processes will be required to comply 
with the Good Manufacturing Practices ("GMP") regulations of the FDA. These 
regulations include design, testing, production, control, documentation and 
other requirements. Enforcement of GMP regulations has increased 
significantly in the last several years, and the FDA has publicly stated that 
compliance will be more strictly scrutinized. The Company's facilities and 
manufacturing processes, as well as those of any future third-party 
suppliers, will be subject to periodic inspection by the FDA, the California 
Department of Health Services and other agencies. To date, the Company has 
only undergone inspection for ISO 9001 certification. Failure to comply with 
these and other applicable regulatory requirements could result in, among 
other things, warning letters, fines, injunctions, civil penalties, recall or 
seizure of products, total or partial suspension of production, refusal of 
the government to grant premarket clearance or premarket approval for 
devices, withdrawal of clearances or approvals and criminal prosecution, 
which could have a material adverse effect on the Company's business, 
financial condition and results of operations.


                                       19


     HIGHLY COMPETITIVE MARKET; RISK OF ALTERNATIVE THERAPIES; RISK OF REUSE. 
The medical device industry and the market for treatment of cardiovascular 
disease, in particular, are characterized by rapidly evolving technology and 
intense competition. A number of competitors, including Johnson & Johnson, 
Boston Scientific Corporation, Cordis Corporation, Guidant Corporation and 
Medtronic, Inc., are currently marketing stents, catheters, lasers, drugs and 
other less invasive means of treating cardiovascular disease. Many of these 
less invasive treatments and CABG surgery are widely accepted in the medical 
community and have a long history of safe and effective use. Many of the 
Company's competitors have substantially greater capital resources, name 
recognition and expertise in and resources devoted to research and 
development, manufacturing and marketing and obtaining regulatory clearances 
or approvals. Furthermore, competition in the emerging market for minimally 
invasive cardiothoracic surgery is expected to be intense and to increase. 
Heartport, Inc., Medtronic, Inc., Research Medical Inc. and United States 
Surgical Corp. are marketing or have announced that they are developing 
products to be used in minimally invasive coronary procedures. There can be 
no assurance that the MIDCAB procedure will replace any current treatments. 
Additionally, even if it is widely adopted, there can be no assurance that 
the Company's competitors will not succeed in developing or marketing 
alternative procedures and technologies or competing devices to perform the 
same procedure or therapeutic drugs that are more effective than the 
Company's products or that render the Company's products or technologies 
obsolete or not competitive. In addition, there can be no assurance that 
existing products for other surgical uses will not be used in MIDCAB 
procedures. Furthermore, sales of the CTS MIDCAB System could be adversely 
affected by reuse of the Company's products, notwithstanding the instructions 
in the Company's clinical protocols and product labeling indicating that each 
of the components of the CTS MIDCAB System is a single-use device. Such 
competition or reuse could have a material adverse effect on the Company's 
business, financial condition and results of operations.
     
     DEPENDENCE ON LICENSES, PATENTS AND PROPRIETARY TECHNOLOGY.  The 
Company's ability to compete effectively will depend in part on its ability 
to develop and maintain proprietary aspects of its technology. The Company 
owns two issued United States patents. The issued patents do not contain any 
claims that protect the Company's products that are currently under 
development. The Company is the licensee of a United States patent 
application for bipolar electrosurgical scissors that are used in the 
Saphenous Vein Harvesting System. The Company has filed twenty-one patent 
applications. There can be no assurance that any issued patents or any 
patents which may be issued as a result of the Company's licensed patent 
application or United States and international patent applications will 
provide any competitive advantages for the Company's products or that they 
will not be successfully challenged, invalidated or circumvented in the 
future. In addition, there can be no assurance that competitors, many of 
which have substantial resources and have made substantial investments in 
competing technologies, will not seek to apply for and obtain patents that 
will prevent, limit or interfere with the Company's ability to make, use and 
sell its products either in the United States or in international markets.
     
     The medical device industry has been characterized by extensive 
litigation regarding patents and other intellectual property rights, and 
companies in the medical device industry have employed intellectual property 
litigation to gain a competitive advantage. There can be no assurance that 
the Company will not become subject to patent infringement claims or 
litigation or interference proceedings declared by the United States Patent 
and Trademark Office ("USPTO") to determine the priority of inventions. The 
defense and prosecution of intellectual property suits, USPTO interference 
proceedings and related legal and administrative proceedings are both costly 
and time-consuming. Litigation may be necessary to enforce patents issued to 
the Company, to protect trade secrets or know-


                                       20


how owned by the Company or to determine the enforceability, scope and 
validity of the proprietary rights of others. Any litigation or interference 
proceedings will result in substantial expense to the Company and significant 
diversion of effort by the Company's technical and management personnel. An 
adverse determination in litigation or interference proceedings to which the 
Company may become a party, including any litigation that may arise against 
the Company as described in "Potential Litigation" below, could subject the 
Company to significant liabilities to third parties or require the Company to 
seek licenses from third parties or prevent the Company from selling its 
products in certain markets, or at all. Costs associated with settlements, 
licensing and similar arrangements, may be substantial and could include 
ongoing royalties. Furthermore, there can be no assurance that the necessary 
licenses would be available to the Company on satisfactory terms, if at all. 
Adverse determinations in a judicial or administrative proceeding or failure 
to obtain necessary licenses could prevent the Company from manufacturing and 
selling its products, which would have a material adverse effect on the 
Company's business, financial condition and results of operations.

     Congress enacted legislation, which became effective October 1, 1996, 
that places certain restrictions on the ability of medical device 
manufacturers to enforce certain patent claims, relating to surgical and 
medical methods, against medical practitioners. Such limitation in the 
enforceability of patent claims, relating to medical and surgical methods, 
against medical practitioners could have a material adverse effect on the 
Company's ability to protect its proprietary methods and procedures against 
medical practitioners.

     In addition to patents, the Company relies on trade secrets and 
proprietary know-how, which it seeks to protect, in part, through 
confidentiality and proprietary information agreements. There can be no 
assurance that such confidentiality or proprietary information agreements 
will not be breached, that the Company would have adequate remedies for any 
breach, or that the Company's trade secrets will not otherwise become known 
to or be independently developed by competitors.
     
     POTENTIAL LITIGATION.  Heartport, Inc. (formerly Stanford Surgical 
Technologies, Inc.), the former employer of the Company's founder and Chief 
Technical Officer, Charles S. Taylor, has alleged in certain correspondence 
that Mr. Taylor and the Company may have misappropriated trade secrets of the 
former employer and breached confidentiality obligations to the former 
employer. The former employer also claims an ownership interest in certain 
developments and products of the Company. The Company has agreed to provide 
for the defense of Mr. Taylor in the event that litigation is commenced. 
Litigation is subject to inherent uncertainties, especially in cases where 
complex technical issues are decided by a lay jury. Accordingly, no assurance 
can be given that if a lawsuit is commenced it would not be decided against 
the Company. Such an adverse determination could have a material adverse 
effect upon the Company's business, financial condition and results of 
operations.
     
     EARLY STAGE OF DEVELOPMENT AND COMMERCIALIZATION; NO ASSURANCE OF 
ABILITY TO MANAGE GROWTH.  The Company believes that the CTS MIDCAB System 
could address a large potential market. There can be no assurance that the 
Company's marketing efforts will result in significant demand for the CTS 
MIDCAB System , or that the initial demand for the Company's products will 
grow. Even if demand for the Company's products does grow, there can be no 
assurance that the Company will be able to develop the necessary 
manufacturing capability; build and train the necessary manufacturing, sales 
and marketing teams; attract, retain and integrate the required key 
personnel; or implement the financial and management systems to meet growing 
demand for its products. Failure of the Company to successfully manage its 
growth would have a material adverse effect on the Company's business, 
financial condition and results of operations.


                                       21

     
     DEPENDENCE UPON KEY PERSONNEL.  The Company's ability to operate 
successfully depends in significant part upon the continued service of 
certain key scientific, technical, managerial and finance personnel, and its 
continuing ability to attract and retain additional highly qualified 
scientific, technical, managerial and finance personnel. Competition for such 
personnel is intense, and there can be no assurance that the Company can 
retain such personnel or that it can attract or retain other highly qualified 
scientific, technical, managerial and finance personnel in the future, 
including key manufacturing, sales and marketing personnel. The loss of key 
personnel or the inability to hire or retain qualified personnel could have a 
material adverse effect upon the Company's business, financial condition and 
results of operations. In addition, many employees of the Company, including 
a number of its key scientific, technical and managerial personnel, are 
subject to the terms of confidentiality agreements with respect to 
proprietary information of their former employers. The failure of these 
employees to comply with the terms of their agreements with, or other 
obligations to, such former employers could result in assertion of claims 
against the Company and such employees, which, if successful, could restrict 
their role with the Company and have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     DEPENDENCE UPON SCIENTIFIC ADVISORS.  The Company has established a 
Scientific Advisory Board including cardiothoracic surgery opinion leaders, 
prominent surgeons and leading interventional cardiologists who the Company 
believes have performed the vast majority of MIDCAB procedures. Members of 
the Scientific Advisory Board consult with the Company regarding research and 
development efforts at the Company, but are employed elsewhere on a full-time 
basis. As a result, they can only spend a limited amount of time on the 
Company's affairs. Although the Company has entered into consulting 
agreements, with terms ranging from six months to four years, and 
confidentiality agreements with each of the members of its Scientific 
Advisory Board, there can be no assurance that the consulting and 
confidentiality agreements between the Company and each of the members of the 
Scientific Advisory Board will not be terminated or breached, and there can 
be no assurance that any of such agreements will be renewed upon expiration.

     LIMITED SALES, MARKETING AND DISTRIBUTION EXPERIENCE.  The Company 
currently has a small sales and marketing organization. The Company intends 
to sell the CTS MIDCAB System in the United States and certain European 
countries through a direct sales force. In other markets, the Company intends 
to sell its products primarily through distributors or by means of 
collaborative arrangements. There can be no assurance that the Company will 
be able to build a larger direct sales force or marketing organization, that 
maintaining a direct sales force or marketing organization will be cost 
effective, or that the Company's sales and marketing efforts will be 
successful. There can be no assurance that the Company will be able to 
maintain agreements with distributors or collaborative arrangements, or that 
such distributors or collaborators will devote adequate resources to selling 
the Company's products under development. The Company has entered into 
distribution agreements for the sale of its products in certain countries, 
therefore the Company will be dependent upon the efforts of these third 
parties, and there can be no assurance that such efforts will be successful. 
Failure to build an effective sales and marketing organization or to 
establish effective distribution or collaborative relationships could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     NO MANUFACTURING EXPERIENCE; SCALE-UP RISK.  The Company has no 
experience manufacturing its products in the volumes that would be necessary 
for the Company to achieve significant commercial sales. There can be no 
assurance that reliable, high-volume manufacturing can be established or


                                       22


maintained at commercially reasonable costs. Companies often encounter 
difficulties in scaling up production, including problems involving 
production yield, quality control and assurance, and shortages of qualified 
personnel. In addition, the Company's manufacturing facilities will be 
subject to GMP regulations, international quality standards and other 
regulatory requirements. Difficulties encountered by the Company in 
manufacturing scale-up or failure by the Company to implement and maintain 
its facilities in accordance with GMP regulations, international quality 
standards or other regulatory requirements could entail a delay or 
termination of production, which could have a material adverse effect on the 
Company's business, financial condition and results of operations.
     
     POTENTIAL COMPONENT SHORTAGES; DEPENDENCE ON SOLE SOURCES OF SUPPLY.  
The Company contracts with third parties for the manufacture of certain 
components or the performance of certain processes involved in the 
manufacturing cycle. Some of these components and processes may only be 
available from single-source vendors. Any prolonged supply interruption or 
yield problems experienced by the Company due to a single-source vendor could 
have a material adverse effect on the Company's ability to manufacture its 
products under development until a new source of supply is qualified. As the 
Company increases production, it may from time to time experience lower than 
anticipated yields or production constraints, resulting in delayed product 
shipments, which could have a material adverse effect on the Company's 
business, financial condition and results of operation.
     
     UNCERTAINTY RELATING TO THIRD-PARTY REIMBURSEMENT.  In the United 
States, health care providers, such as hospitals and physicians, that 
purchase medical devices, such as the Company's products, generally rely on 
third-party payors, principally Medicare, Medicaid and private health 
insurance plans, to reimburse all or part of the cost of the procedure in 
which the medical device is being used. Reimbursement for cardiovascular 
surgery, including CABG surgery, using devices that have received FDA 
approval has generally been available in the United States. In addition, 
certain health care providers are moving toward a managed care system in 
which such providers contract to provide comprehensive health care for a 
fixed cost per person. The Company is unable to predict what changes will be 
made in the reimbursement methods utilized by third-party health care payors. 
The Company could be adversely affected by changes in reimbursement policies 
of government or private health care payors, particularly to the extent any 
such changes affect reimbursement for the procedures in which the Company's 
products are intended to be used. Failure by physicians, hospitals and other 
potential users of the Company's products under development to obtain 
sufficient reimbursement from health care payors for the procedure in which 
the Company's products are intended to be used or adverse changes in 
government and private third-party payors' policies toward reimbursement for 
such procedures could have a material adverse effect on the Company's 
business, financial condition and results of operations.
     
     Market acceptance of the Company's products in international markets 
will be dependent, in part, upon the availability of reimbursement within 
prevailing health care payment systems. Reimbursement and health care payment 
systems in international markets vary significantly by country, and include 
both government sponsored health care and private insurance. The Company 
intends to seek international reimbursement approvals, although there can be 
no assurance that any such approvals will be obtained in a timely manner, if 
at all, and failure to receive international reimbursement approvals could 
have a material adverse effect on market acceptance of the Company's products 
in the international markets in which such approvals are sought.
     
     RISKS RELATING TO INTERNATIONAL OPERATIONS.  The Company plans to market 
its products in international markets. Changes in overseas economic 
conditions, currency exchange rates, foreign tax


                                       23


laws, or tariffs or other trade regulations could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. The anticipated international nature of the Company's business is 
also expected to subject it and its representatives, agents and distributors 
to laws and regulations of the foreign jurisdictions in which they operate or 
the Company's products are sold. The regulation of medical devices in a 
number of such jurisdictions, particularly in the European Union, continues 
to develop and there can be no assurance that new laws or regulations will 
not have an adverse effect on the Company's business, financial condition and 
results of operations. In addition, the laws of certain foreign countries do 
not protect the Company's intellectual property rights to the same extent as 
do the laws of the United States.
     
     PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE.  The development, 
manufacture and sale of medical products entail significant risk of product 
liability claims and product recalls. The Company's current product liability 
insurance coverage limits are $3,000,000 per occurrence and $3,000,000 in the 
aggregate, and there can be no assurance that such coverage limits are 
adequate to protect the Company from any liabilities it might incur in 
connection with the development, manufacture and sale of its products. In 
addition, the Company may require increased product liability coverage as 
product sales increase. Product liability insurance is expensive and in the 
future may not be available to the Company on acceptable terms, if at all. A 
successful product liability claim or series of claims brought against the 
Company in excess of its insurance coverage or a product recall could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.
     
     POSSIBLE FUTURE CAPITAL REQUIREMENTS.  The Company's capital 
requirements depend on numerous factors, including the progress of the 
Company's product development programs, the receipt of and the time required 
to obtain regulatory clearances or approvals, the resources the Company 
devotes to developing, manufacturing and marketing its products, the extent 
to which the Company's products generate market acceptance and demand, and 
other factors. The Company expects to devote substantial capital resources 
for research and development, to hire and develop a larger direct sales force 
in the United States and to expand manufacturing capacity and facilities. The 
timing and amount of such capital requirements cannot be accurately 
predicted. Consequently, the Company may be required to raise additional 
funds through public or private financing, collaborative relationships or 
other arrangements. There can be no assurance that the Company will not 
require additional funding or that such additional funding, if needed, will 
be available on terms attractive to the Company, or at all, which could have 
a material adverse effect on the Company's business, financial condition and 
results of operations. Any additional equity financing may be dilutive to 
stockholders, and debt financing, if available, may involve restrictive 
covenants.
     
     POTENTIAL VOLATILITY OF STOCK PRICE.  The stock markets have experienced 
price and volume fluctuations that have particularly affected medical 
technology companies, resulting in changes in the market prices of the stocks 
of many companies that may not have been directly related to the operating 
performance of those companies. Such broad market fluctuations may adversely 
affect the market price of the Company's Common Stock. In addition, the 
market price of the Common Stock may be highly volatile. Factors such as 
variations in the Company's financial results, comments by securities 
analysts, announcements of technological innovations or new products by the 
Company or its competitors, changing government regulations and developments 
with respect to FDA submissions, patents, proprietary rights or litigation 
may have a significant adverse effect on the market price of the Common Stock.
     
     SIGNIFICANT RESTRICTIONS ON CHANGE OF CONTROL.  The Company has adopted 
a number of anti-


                                       24


takeover measures.  The Company has adopted a Preferred Shares Rights 
Agreement, sometimes referred to as a poison pill, designed to prevent 
hostile takeovers not approved by the Board of Directors.  In addition, the 
company is authorized to issue 5,100,000 shares of undesignated Preferred 
Stock. Such shares of Preferred Stock may be issued by the Company without 
stockholder approval upon such terms as the Company's Board of Directors may 
determine.  The issuance of Preferred Stock may have the effect of delaying, 
deferring or preventing a change in control of the Company, may discourage 
bids for the Company's Common Stock at a premium over the market price of the 
Common Stock and may adversely affect the market price of and the voting and 
other rights of, the holders of Common Stock,  At present, the Company has no 
plans to issue any of the Preferred Stock.

ITEM 2.  PROPERTIES

     The Company currently leases a 23,500 square foot facility in Cupertino, 
California.  It includes an environmentally controlled, Class 10,000 clean 
room for assembly together with laboratory, machine shop, warehouse and 
office space. The lease expires on June 1, 2001.  The Company estimates this 
space to be sufficient through 1997 and is currently evaluating its 
requirements for 1998 and beyond.
     
ITEM 3.  LEGAL PROCEEDINGS
     
     The Company is not currently party to any legal proceeding.

     Heartport, Inc. (formerly Stanford Surgical Technologies, Inc.), the 
former employer of the Company's founder and Chief Technical Officer, Charles 
S. Taylor, has alleged in certain correspondence that Mr. Taylor and the 
Company may have misappropriated trade secrets of the former employer and 
breached confidentiality obligations to the former employer. The former 
employer also claimed an ownership interest in certain developments and 
products of the Company. The Company has agreed to provide for the defense of 
Mr. Taylor, in the event that litigation is commenced. The Company has 
conducted a review of its technology in light of the claims of the former 
employer and, after consultation with intellectual property counsel and with 
Mr. Taylor, believes that Mr. Taylor and the Company should prevail if 
litigation is commenced. However, litigation is subject to inherent 
uncertainties, especially in cases where complex technical issues are decided 
by a lay jury. Accordingly, no assurance can be given that, if a lawsuit is 
commenced, it would not be decided against the Company. Such an adverse 
determination could have a material adverse effect upon the Company's 
business, financial condition and results of operations.
