ATS Medical Reports on Regulatory Progress for the ATS 3f(R) Aortic Bioprosthesis

Australian Government Provides Conditional Approval to Import

Application for Canadian Approval Submitted

United States FDA Completes Successful Site Inspection

MINNEAPOLIS, Feb. 28 (HSMN NewsFeed) -- ATS Medical, Inc. (Nasdaq: ATSI ) today reported several regulatory developments relating to the ATS 3f® Aortic Bioprosthesis. Conditional approval to import the prosthesis has been granted by the Australian Government's Department of Health and Aging, Therapeutics Goods Administration. With the Australian approval, the ATS 3f Aortic Bioprosthesis is now approved for distribution in 15 countries.

ATS Medical also reported that a submission for approval has been completed and delivered to Health Canada - Medical Device Bureau, Therapeutic Products Programme. The company will be actively working with the agency to ensure a complete and timely process. In addition, the United States Food & Drug Administration (FDA) recently conducted a successful site inspection of the Lake Forest, California manufacturing facility as part of the PMA process. These developments are highlights of the rapid progress achieved to date in expanding availability of the Company's first bioprosthetic offering to global markets.

The ATS 3f Aortic Bioprosthesis incorporates revolutionary design concepts intended to preserve native aortic root geometry and function. Through this unique approach, the prosthesis more closely mimics native valve function providing excellent hemodynamic performance that may contribute to improvements in key determinants of cardiovascular performance such as coronary blood flow and left ventricular mass regression. Promising data suggests that physiologic stresses, a detriment to bioprosthetic valve longevity, may be more efficiently distributed throughout the prosthetic's leaflets leading to improved durability.

ATS Medical has also worked closely with cardiovascular surgeons to refine the product's implant process. A proprietary holder system has been developed to aid in the prompt, consistent, and reproducible placement of the device. A new time saving preparatory product rinse procedure has also been developed, validated, and approved for clinical use. By virtue of its design the ATS 3f Aortic Bioprosthesis sets new standards for ease of implant. In the words of leading implant surgeon, Mr. Gianfranco Campalani, DMS, of the Royal Victoria Hospital, Belfast, Northern Ireland, "We were pleasantly surprised to find the combination of the new rinse procedure and holder system contributed to a noticeable decrease in implant time. A straight forward operative procedure is now even easier."

Michael Dale, President and CEO of ATS Medical noted, "We are very pleased with the rapid progress we are making to bring our first bioprosthesis to the global marketplace. Our continuing introduction of new products and innovations to the field of cardiac surgery allows us to further leverage the infrastructure we have built as we establish a foothold in the largest and fastest growing segment of the heart valve therapy marketplace."
