FOR IMMEDIATE RELEASE

           ATS MEDICAL REPORTS STRONG SECOND QUARTER FINANCIAL RESULTS
         US Sales Grow 32% Year-Over-Year, International Sales Grow 19%
          Business Development Effort Increases Revenue Diversification

MINNEAPOLIS, July 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 second quarter of 2005 increased
23.3% to $9.3 million, compared with sales of $7.5 million for the second
quarter of 2004. Mechanical heart valve sales represented 94% of total revenue
while other products and services represented 6% of total revenue. There was no
meaningful impact on revenue from foreign currency exchange. The net loss for
the second quarter of 2005 was $3.1 million, or $0.10 per share, compared with a
net loss of $3.4 million, or $0.12 per share, in the second quarter of 2004.
For the first six months of 2005, sales increased 14.9% to $16.4 million,
compared with sales of $14.2 million for the first six months of 2004. The net
loss for the first half of 2005 was $7.1 million, or $0.23 per share, compared
with $6.7 million or $0.25 per share for the same period a year ago.

"During the quarter, we continued to make considerable progress on our strategy
to become a diversified provider of state of the art products and services for
the cardiovascular surgeon," said Michael Dale, Chairman, President and CEO. "As
expected, we regained sales momentum in our international markets, and continued
our momentum in the US. Additionally, we entered into two new strategic
agreements that further diversify the product portfolio we offer the
cardiovascular surgeon while increasing our product pipeline and leveraging our
sales and marketing infrastructure.

"In addition, we continue to make operational progress. Our inventories have
declined more than $5.0 million since June 2004. Manufacturing efficiencies and
product diversification have resulted in a gross margin of 41.2%, a meaningful
increase from the 28.1% gross margin we





recorded in the second quarter of 2004. 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.

"Looking ahead, our momentum with the ATS Open Pivot(R) mechanical heart valve,
our strong start with CryoCath, and the implementation of our recent agreement
with Regeneration Technologies' Cardiovascular division makes us confident about
our outlook for the remainder of 2005. We continue to believe we will generate
total sales growth for the full year of between 20% and 25% compared with 2004,
which implies a net sales range of $33 million to $35 million. In addition,
revenue diversification should also increase as the second half of the year
progresses. 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 our
cash balances to support this effort, as well as other business operations,
remains sufficient to see us through to profitability. We continue to expect to
achieve our profitability milestone during 2006," concluded Mr. Dale.
