ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On November 9, 2004, ATS Medical, Inc. (ATS) entered into two
agreements with CryoCath Technologies, Inc. (CryoCath), a Canadian company,
pursuant to which ATS will market CryoCath's surgical cryotherapy products for
cardiac arrhythmias in the United States and in select international markets.

         Under the first agreement, which is applicable in the United States,
ATS will act as an exclusive agent co-promoting (with CroyCath) CryoCath's
surgical cryotherapy products for cardiac arrhythmias to present and future
customers in exchange for customary commissions. Under the second agreement,
which is applicable outside the United Sates, ATS will act as exclusive
distributor for CryoCath's surgical cryotherapy products for cardiac arrhythmias
in all non-U.S. countries except those in which CryoCath has pre-existing
contractual obligations with other third party distributors.

         The agreements contain minimum performance levels that ATS is required
to achieve in order to maintain its rights under the agreements. If these
performance levels are not achieved, CryoCath has the right to cancel the
agreements or convert ATS' rights from exclusive to non-exclusive. CryoCath also
has the right to terminate the agreements, even if ATS has met its minimum
performance levels, by giving one year's notice and payment of a termination fee
based on the level of product sales.

         For certain CryoCath customers to which ATS will market, ATS has agreed
to make a payment to CryoCath representing a portion of the prior year's sales
to these customers and future payments of a certain percentage of sales
occurring over the following three year period. These payments are refundable to
ATS upon cancellation of the agreements.
