1.	execute for
me and on my behalf, in my capacity as an officer and/or director of ATS

Securities Exchange Act of 1934, as amended, and the rules promulgated
thereunder;

which may be necessary or desirable to complete and execute any such Form
3, 4, or 5, complete and execute any amendment or amendments thereto, and
timely file such Form with the United States Securities and Exchange
Commission and any stock exchange or similar authority; and
3.	take any
other action of any type whatsoever in connection with the foregoing which,
in the opinion of such attorney-in-fact, may be of benefit to me, in my
best interest or legally required by me, it being understood that the
documents executed by such attorney-in-fact on my behalf pursuant to this
Power of Attorney shall be in such form and shall contain such terms and
conditions as such attorney-in-fact may approve in such attorney-in-facts
discretion.
I hereby grant to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever
requisite, necessary or proper to be done in the exercise of any of the

all that such attorney-in-fact, or such attorney-in-facts substitute or
substitutes, shall lawfully do or cause to be done by virtue of this Power
of Attorney and the rights and powers herein granted.  I acknowledge that
the attorneys-in-fact named above, in serving in such capacity at my
request, are not assuming, nor is ATS Medical, Inc. assuming, any of my

This Power of Attorney shall remain in full force
and effect until I am no longer required to file Forms 3, 4, and 5 with
respect to my holdings of and transactions in securities of ATS Medical.
Inc., unless earlier revoked by me in a signed writing delivered to the
