FOR IMMEDIATE RELEASE

            ATS MEDICAL REPORTS 27.3% INCREASE IN THIRD QUARTER SALES

                       US SALES GROW 69.3% YEAR-OVER-YEAR
    BUSINESS DEVELOPMENT EFFORT RESULTS IN INCREASED REVENUE DIVERSIFICATION

MINNEAPOLIS, OCTOBER 27 -- ATS Medical, Inc. (Nasdaq: ATSI), developer,
manufacturer and marketer of state-of-the-art cardiac surgery products and
services, today reported that sales for the third quarter of 2005 increased
27.3% to $8.3 million, compared with sales of $6.5 million for the third quarter
of 2004. Mechanical heart valve sales represented 85.5% of total revenue while
other products and services represented 14.5% of total revenue. There was no
meaningful impact on revenue from foreign currency exchange. The net loss for
the third quarter of 2005 decreased to $4.1 million, or $0.13 per share,
compared with a net loss of $4.5 million, or $0.15 per share, in the third
quarter of 2004. Included in the net loss amount in the third quarter of 2005 is
$0.7 million relating to a lower of cost or market inventory adjustment and in
the net loss amount in the third quarter of 2004 is $0.4 million in factory
production ramp-up costs, both recorded as additional cost of sales.

For the first nine months of 2005, sales increased 18.8% to $24.7 million,
compared with sales of $20.8 million for the first nine months of 2004. The net
loss for the first nine months of 2005 was $11.2 million, or $0.36 per share,
compared with $11.2 million or $0.40 per share for the same period a year ago.

"Our strong third quarter growth illustrates the success of our strategy to
diversify the product portfolio and leverage our sales and marketing
infrastructure," said Michael Dale, Chairman, President and CEO. "While we
generated solid year-over-year revenue growth with our ATS Open Pivot(R)
mechanical heart valves, especially in the U.S. market, our other products and
services added during 2005 represented 14.5% of our total revenue. This revenue
contribution compares with only 4% in the second quarter. The cardiovascular
surgeon is increasingly looking to ATS to provide state of the art products and
services that enhance patient outcomes."




"In addition, we continue to make operational progress. Our inventories have
declined $4.6 million from the September 30, 2004 level," continued Mr. Dale.
"Manufacturing efficiencies and product diversification are improving margins.
Our gross margin increased to 31.4% in the third quarter of 2005 from 20.9%
during the same period in 2004. After making allowances for lower of cost or
market and factory production ramp-up costs, gross margin improved to 39.8%
during the just completed quarter versus 27.2% in the prior year. Overall
inventories will continue to decline during the remainder of 2005. Operating
costs and most importantly, selling and marketing costs, have remained flat over
the past three quarters, while G&A expense has increased due to costs to comply
with Sarbanes Oxley and the expensing of restricted stock units."

"Looking ahead, we are highly optimistic about our ability to achieve
approximately $35 million in revenue for the full year 2005, which is at the
upper end of the guidance we provided at the beginning of 2005," Continued Mr.
Dale. "In addition to the solid momentum generated in the marketplace by our
Open Pivot mechanical heart valve, our new products and services are being well
received by the cardiovascular surgeon and we expect to achieve a $10 million
revenue quarter for the first time in the Company's history for the period
ending December 31, 2005. Our product development efforts are on schedule and we
remain particularly excited about the market potential of the PARSUS(TM) blood
filtration technology."

"We've also established some preliminary goals for 2006," continued Mr. Dale.
"Based on current operations, our goal is to grow revenue next year by 20 to 25
percent. We also continue to expect that we will consume our remaining high cost
pyrolytic carbon inventory early in 2006. Our strategy to self-manufacture 100%
of our future product component requirements remains on schedule and we
currently expect to achieve operating profitability during the second half of
2006."

"While our cash balances and credit facilities are sufficient to support our
current product and service lines, in early October we raised more than $22
million to fund our business development effort," continued Mr. Dale. "Our goal
with these resources is to continue to expand our product and service portfolio
so that ATS can become the provider of choice to the cardiovascular surgeon and
achieve significant gains in revenue. To date we have made substantial progress
towards our goals and we continue to devote significant time to our
diversification effort," concluded Mr. Dale.

DISCLOSURE OF NON-GAAP FINANCIAL MEASURES

ATS reports its financial results in accordance with generally accepted
accounting principles ("GAAP"). In addition, from time to time, we include other
measures in our releases which are not prepared in accordance with GAAP.
Investors should consider these non-GAAP measures in addition to, not as a
substitute for or as superior to, financial reporting measures prepared in
accordance with GAAP. In this release we have included adjusted versions of our
gross margin percentages for the third quarters of 2005 and 2004. These non-GAAP
measures do not reflect a lower of cost or market inventory adjustment in the
third quarter of 2005 and certain factory production ramp-up costs in the third
quarter of 2004 because we believe that these charges will not be incurred on a
regular basis. We use the adjusted gross margin measure in our internal analysis
and review of our operational performance. We believe that these non-GAAP
measures provide investors with useful information in comparing our performance
over different periods, particularly when comparing one of these periods to a
period in which we did not incur these




kind of charges. By using these non-GAAP measures we believe investors get a
better picture of the performance of our underlying business. We have also
included as an attachment to this release a schedule which reconciles our gross
margin percentage calculated using numbers prepared in accordance with GAAP to
our adjusted gross margin percentages presented above.
