                                ATS MEDICAL, INC.
                                 PROXY STATEMENT

         This proxy statement is furnished in connection with the solicitation
of the enclosed proxy by the Board of Directors of ATS Medical, Inc. (the
"Company") for use at the 2001 Annual Meeting of Shareholders to be held on
Tuesday, May 1, 2001 at 3:30 p.m. at the Minneapolis Club, 729 Second Avenue
South, Minneapolis, Minnesota 55402, and at any adjournments thereof.
Shareholders who sign and return a proxy may revoke it at any time before it is
voted by giving written notice to the Secretary of the Company. This proxy
statement and the enclosed proxy card are being mailed to shareholders
commencing on or about April 3, 2001.

         Proxies that are completed, signed and returned to the Company prior to
the Annual Meeting will be voted as specified. If no direction is given, the
proxy will be voted for the election of the nominees for director named in this
proxy statement and for the management proposals discussed herein and in
accordance with the judgment of the persons named in the proxy as to any other
matters that properly come before the meeting. If a shareholder abstains from
voting as to any matter (or indicates a "withhold vote for" as to directors),
then the shares held by such shareholder shall be deemed present at the Annual
Meeting for purposes of determining a quorum and for purposes of calculating the
vote with respect to such matter, but shall not be deemed to have been voted in
favor of such matter. If a broker returns a "non-vote" proxy, indicating a lack
of authority to vote on such matter, then the shares covered by such non-vote
shall be deemed present at the Annual Meeting for purposes of determining a
quorum but shall not be deemed to be represented at the Annual Meeting for
purposes of calculating the vote with respect to such matters.

proxy is intended to be voted for the election of nominees for director named

specified on the proxy card. The affirmative vote of a majority of the shares of
common stock of the Company (the "Common Stock") represented at the Annual

not permitted. In the event that any nominee becomes




unable or unwilling to serve as a director for any reason, the persons named in

best judgment. The Board of Directors has no reason to believe that any nominee
will be unable or unwilling to serve as a director if elected.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

         The Audit Committee of our Board of Directors is composed of the
following non-employee directors: Mr. Boehnen, Mr. Cuddihy and Mr. Graf. Mr.
Boehnen currently serves as the Chairman of the Audit Committee. All of the
members of the Audit Committee are independent for purposes of the Nasdaq
listing requirements. The Audit Committee operates under a written charter
adopted by the Board of Directors, a copy of which is attached to this Proxy
Statement as Exhibit A. The Audit Committee recommends to the Board of
Directors, and submits for shareholder ratification, the appointment of our
independent auditors Ernst & Young LLP.

         Management is responsible for the Company's internal controls and the
financial reporting process. Our independent auditors are responsible for
performing an independent audit of our consolidated financial statements in
accordance with generally accepted auditing standards and to issue a report on
our financial statements. The Audit Committee's responsibility is to monitor and
oversee these processes.

         In this context, the Audit Committee has met and held discussions with
management and the independent auditors. Management represented to the Audit
Committee that the Company's consolidated financial statements were prepared in
accordance with generally accepted accounting principles, and the Audit
Committee has reviewed and discussed the consolidated financial statements with
management and the independent auditors. The Audit Committee discussed with the
independent auditors matters required to be discussed by Statement on Auditing
Standards No. 61 (Communications with Audit Committees).

         Our independent auditors also provided to the Audit Committee the
written disclosure required by Independence Standards Board Standard No. 1
(Independence Discussions with Audit Committees), and the Audit Committee
discussed with the independent auditors the auditing firm's independence. The
Committee also considered whether non-audit services provided by the independent
auditors during the last fiscal year were compatible with maintaining the
independent auditors' independence.


                                       4



         Based upon the Audit Committee's discussion with management and the
independent auditors and the Audit Committee's review of the representation of
management and the report of the independent auditors to the Audit Committee,
the Audit Committee recommended to the Board of Directors that the audited
consolidated financial statements be included in Company's Annual report on Form
10-K for the fiscal year ended December 31, 2000 filed with the Securities and
Exchange Commission.

                                        Members of the Audit Committee
                                        David L. Boehnen, Chairman
                                        Charles F. Cuddihy, Jr.
                                        A. Jay Graf


COMPENSATION OF DIRECTORS

         The Directors of the Company do not receive any cash compensation for
their services on the Board of Directors. Upon their initial election to the
Board of Directors, each outside Director receives an option to purchase 5,000
shares of Common Stock at the fair market value on the date of election under
the 1987 Stock Option and Stock Award Plan (the "Plan"). Upon each reelection,
each outside Director receives an option to purchase 2,500 shares of Common
Stock at the fair market value on the date of reelection under the Plan. On May
4, 2000, each outside Director was granted a fully vested stock option for
50,000 shares at an exercise price of $9.875 per share (the fair market value on

option for 50,000 shares with an exercise price of $9.875 per share vesting at a
rate of 25% on each anniversary over the next four years. The outside Directors
received these grants in recognition of their past and continuing contributions
to the Company and to bring their grants to a level commensurate with that of
directors at companies comparable to the Company.

                          CHANGE IN CONTROL AGREEMENTS

     The Company has entered into agreements with its officers providing for the
payment of certain benefits to the officers if their employment terminates
following a "change in control" of the Company. The Agreements provide for
benefits if an officer's employment is terminated within 24 months following a
change in control unless such termination was by the Company for cause, by the
officer other than for "good reason," or because of the officer's death. "Good
reason" is defined as the termination of employment as a result of either a
diminishment in the officer's responsibilities, a reduction in salary or
benefits, a relocation of the Company's office of more than 35 miles or any
reason during the sixth month following a change in control. A "change in
control" is generally defined as an acquisition of more than 20% of the
outstanding Common Stock by any person or group, the merger or sale of the
Company or the replacement of a majority of the Company's Board of Directors
with directors not recommended by the existing Board of Directors. The
Agreements provide for lump sum payments following termination in amounts equal
to three times the sum of the officer's base salary and any annual target bonus
potential, as limited by Section 280G of the Internal Revenue Code of 1986, as
amended (the "Code"). If there had been a change in control of the Company as of
the end of 2000 and the employment of the five executive officers named in the

                      REPORT OF THE COMPENSATION COMMITTEE
                        CONCERNING EXECUTIVE COMPENSATION

OVERVIEW

         The Compensation Committee is responsible for setting the compensation
and benefits of the Company's executive officers, including the Chief Executive
Officer, on behalf of the Board of Directors and the shareholders. The
Compensation Committee also oversees the operation of the 1998 Employee Stock
Purchase Plan (the "Purchase Plan") and the ATS Medical, Inc. 2000 Stock
Incentive Plan (the "Stock Option Plan").

         The Compensation Committee is composed entirely of outside directors of
the Company. During 2000, the Board elected Messrs. Cuddihy and Graf to serve on
the Compensation Committee. Mr. Cuddihy is Chairman of the Committee.

         The basic objective of the Compensation Committee is to establish a
compensation package which is appropriate for each officer's scale of
responsibility and performance, commensurate with the marketplace compensation
for executives of companies of similar size as the Company, and to attract,
motivate and retain executives of the necessary caliber. The Committee intends
to achieve these objectives by giving executives the opportunity for equity
ownership in the Company through stock options and by awarding bonuses tied to
individual and Company performance as significant elements of the executive
compensation package.

COMPENSATION CRITERIA

         In determining each executive compensation package, the Compensation
Committee reviews the compensation of each executive and the individual
achievements and performance of each such executive during the year. The
Committee considers objective criteria, such as salary survey data of companies
of similar size and technology as the Company, in determining executive
salaries. The financial performance and accomplishments of the Company during
the year are also factors in the Committee's determination of executive
compensation. In line with the Compensation Committee's goal of tying
compensation with performance, executives' salaries are generally increased only
to keep up with estimated cost-of-living expenses, while bonuses vary
substantially from year to year and have generally depended upon the performance
of the Company and the individual executive. The Committee generally makes a
determination as to salaries for the current calendar and reviews bonuses to be
awarded for the prior year at the end of the calendar year or at the beginning
of the following year.


                                       9



         In 2000, the Compensation Committee continued to place emphasis on the
performance-based component of the Company's bonus program to the Company's
executive employees by implementing the Management Incentive Compensation Plan
(the "MICP"). In particular, bonuses to be granted to executive employees
pursuant to the MICP were tied to a grid representing year-over-year increases
in sales and operating income. The Compensation Committee and each executive
officer also develop annual individual objectives which would allow for an
additional 1% of salary bonus for each objective completed, for up to a total of
5% salary bonus.

         In addition, the Compensation Committee, in consultation with the Chief
Executive Officer, generally grants stock options to its executive officers on
an annual basis to maintain and increase the executives' incentive to continue
their long-term employment with the Company. The Compensation Committee may also
approve special grants to certain executives to reward their individual
performance. The overall compensation package may also be varied if the
Committee feels that it is necessary to maintain the Company's executive
compensation in line with companies similar in size and technology to the
Company.

EXECUTIVE COMPENSATION PACKAGE

         The primary components of the executive compensation package are
salary, bonuses and stock option grants. The Company also currently maintains a
variety of employee benefits in which its executive officers may participate,
including health benefits, automobile allowances, disability insurance, matching
contributions to the Company's 401(k) program and discounting the purchase of a
certain number of shares of the Company's Common Stock pursuant to the Stock
Purchase Plan.

         The Compensation Committee took the following actions with respect to
executive compensation for 2000:

         *  Continued the Management Incentive Compensation Plan (MICP) with
            specific goals for 2000.

         *  Each executive officer earned a bonus of 4 to 5% of 2000 salary for
            completion of individual objectives.

          In 2001, the Committee intends to continue to emphasize objective
factors and performance in determining executive compensation, including
maintaining the compensation of the Company's officers at industry levels, as
reflected in surveys of compensation practices in corporations of comparable
size and technology. In addition, the Committee intends to use growth in the
Company's gross revenue and operating income during 2001 as the primary criteria
for determining the size of bonuses to be paid to executive officers for 2001.
The Committee will use stock options as part of executive compensation in 2001
to provide additional performance incentives.


                                       10



         The year 2000 was atypical insofar as the number of stock options
granted to the executive officers and outside members of the Board of Directors.
The Compensation Committee granted the additional options because of 1) full
marketing approval from the FDA, 2) the value of the carbon contract negotiated
with Sulzer-Carbomedics, Inc. and the development of our own carbon facility,
and 3) the foresight and preparation which allowed for a quick start in the
formation of the U.S. Sales and Marketing Team.

COMPENSATION OF THE CHIEF EXECUTIVE OFFICER

         During 2000, the Compensation Committee reviewed the Company's and Mr.
Villafana's performance in order to establish Mr. Villafana's compensation. Mr.
Villafana received a salary increase in 2000 over 1999 of 5% and a salary
increase in 2001 over 2000 of 5%. In addition, Mr. Villafana received a bonus
consisting of 5% of his 2000 annual salary. The Committee's performance review
of Mr. Villafana addressed major areas of accomplishment for the Company.

SECTION 162(m) OF THE INTERNAL REVENUE CODE

         Section 162(m) of the Code generally limits the corporate deduction for
compensation paid to executive officers to $1.0 million, unless the compensation
qualifies as a "performance-based compensation" under the Code. Compensation
resulting from stock options granted under the Stock Option Plan or the ATS
Medical, Inc. 2000 Incentive Plan will not be counted toward the $1.0 million of
deductible compensation under Section 162(m). The Committee does not believe
that the annual compensation for Section 162(m) purposes of any of the Company's
executive officers will exceed $1.0 million in fiscal 2001.

                                          Charles F. Cuddihy, Jr.
                                          A. Jay Graf


SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors and executive officers and all persons who beneficially own more than
10% of the outstanding shares of the Company's Common Stock to file with the
Securities and Exchange Commission initial reports of ownership and reports of
changes in ownership of such Common Stock. Directors, executive officers and 10%
or more beneficial owners are also required to furnish the Company with copies
of all Section 16(a) reports they file. Based solely on a review of the copies
of such forms furnished to the Company, the Company believes that all Section
16(a) filing requirements applicable to its executive officers, directors and
10% shareholders were complied with.

                                ATS MEDICAL, INC.

                             AUDIT COMMITTEE CHARTER

ORGANIZATION

This charter governs the operations of the audit committee. The committee shall
review and reassess the charter at least annually and obtain the approval of the
board of directors. The committee shall be appointed by the board of directors
and shall comprise at least three directors, each of whom are independent of
management and ATS Medical, Inc. ("the Company"). Members of the committee shall
be considered independent if they have no relationship that may interfere with
the exercise of their independence from management and the Company. All
committee members shall be financially literate, (or shall become financially
literate within a reasonable period of time after appointment to the committee,)
and at least one member shall have accounting or related financial management
expertise.

STATEMENT OF POLICY

The audit committee shall provide assistance to the board of directors in
fulfilling their oversight responsibility to the shareholders, potential
shareholders, the investment community, and others relating to the Company's
financial statements and the financial reporting process, the systems of
internal accounting and financial controls, the annual independent audit of the
Company's financial statements, and the legal compliance and ethics programs as
established by management and the board. In so doing, it is the responsibility
of the committee to maintain free and open communication between the committee,
independent auditors and management of the Company. In discharging its oversight
role, the committee is empowered to investigate any matter brought to its
attention with full access to all books, records, facilities and personnel of
the Company and the power to retain outside counsel or other experts for this
purpose.

RESPONSIBILITIES AND PROCESSES

The primary responsibility of the audit committee is to oversee the Company's
financial reporting process on behalf of the board and report the results of
their activities to the board. Management is responsible for preparing the
Company's financial statements, and the independent auditors are responsible for
auditing those financial statements. The committee in carrying out its
responsibilities believes its policies and procedures should remain flexible, in
order to best react to changing conditions and circumstances. The committee
should take the appropriate actions to set the overall corporate "tone" for
quality financial reporting, sound business risk practices and ethical behavior.


                                       A-1



In fulfilling their responsibilities hereunder, it is recognized that members of
the Audit Committee are not full-time employees of the company and are not, and
do not represent themselves to be, accountants or auditors by profession or
experts in the fields of accounting or auditing. As such, it is not the duty or
the responsibility of the Audit Committee or its members to conduct "field work"
or other types of auditing or accounting reviews or procedures, and each member
of the audit committee shall be entitled to rely on (i) the integrity of those
persons and organizations within and outside the company that they receive
information from and (ii) the accuracy of the financial and other information
provided to the Audit Committee by such persons or organizations, absent actual
knowledge of the contrary.

The following shall be the principal recurring processes of the audit committee
in carrying out its oversight responsibilities. The processes are set forth as a
guide with the understanding that the committee may supplement them as
appropriate.

*    The committee shall have a clear understanding with management and the
     independent auditors that the independent auditors are ultimately
     accountable to the board and the audit committee as representatives of the
     Company's shareholders. The committee shall have the ultimate authority to
     evaluate and, where appropriate, replace the independent auditors. The
     committee shall discuss with the auditors their independence from
     management and the Company and the matters included in the written
     disclosures required by the Independence Standards Board. Annually, the
     committee shall review and recommend to the board the selection of the
     Company's independent auditors, subject to shareholders' approval.

*    The committee shall discuss with the independent auditors the overall scope
     and plans for their audits including the adequacy of staffing and
     compensation. Also, the committee shall discuss with management and the
     independent auditors the adequacy and effectiveness of the accounting and
     financial controls, including the Company's system to monitor and manage
     business risk and legal and ethical compliance programs. Further, the
     committee shall meet separately with the independent auditors, with and
     without management present, to discuss the results of their examinations.

*    The committee shall review the interim financial statements with management
     and the independent auditors prior to the filing of the Company's quarterly
     Report on Form 10-Q. Also, the committee shall discuss the results of the
     quarterly review and any other matters required to be communicated to the
     committee by the independent auditors under generally accepted auditing
     standards. The chair of the committee may represent the entire committee
     for the purposes of this review.


                                       A-2



*    The committee shall review with management and the independent auditors the
     financial statements to be included in the Company's Annual Report on Form
     10-K (or the annual report to shareholders if distributed prior to the
     filing of Form 10-K), including their judgment about the quality, not just
     acceptability, of accounting principles, the reasonableness of significant
     judgments, and the clarity of the disclosures in the financial statements.
     Also, the committee shall discuss the results of the annual audit and any
     other matters required to be communicated to the committee by the
     independent auditors under generally accepted auditing standards.

*    Following each annual meeting, the committee shall elect a chair.

*    In order to conduct timely meetings and accommodate individual schedules,
     member(s) of the committee may participate in a meeting by conference call
     or similar communications equipment.
