Noteworthy for ATS Medical are several presentations focusing on the ATS Open Pivot(R) Mechanical Heart Valve and the ATS 3f(R) Aortic Bioprosthesis.

-- "Five Year Hemodynamic Performance of ATS 3f Aortic Bioprosthesis Assessed By Valve Energy Loss and Pressure Gradient," Xu Yu Jin, M.D., Oxford Heart Centre, Oxford, UK, on Sunday, June 28, 2009. -- "The Click Within - Impact of Prosthesis Sound of Composite Grafts on Quality of Life," Mario Stalder, M.D., University Hospital Berne, Berne, Switzerland, on Monday, June 29, 2009. -- "Clinical Experience with the ATS 3f Stentless Aortic Bioprosthesis - Five Years Follow Up," Joerg Linneweber, M.D., Klinik fur kardiovaskulare Chirurgie Charite-Universitatsmedizin Berlin, Berlin, Germany, on Monday, June 29, 2009. -- "Fifteen Years Single Centre Experience with the ATS Bi-leaflet Valve," Professor Guido Van Nooten, University Hospital Ghent, Ghent, Belgium, on Tuesday, June 30, 2009.

Highlighting the ATS exhibition will be the ATS 3f(R) Aortic Bioprosthesis which is designed to replace the patient's diseased valve. The ATS 3f Aortic Bioprosthesis is a revolutionary next generation stentless pericardial aortic tissue valve that is unlike any other valve with its tubular design that restores continuity between the annulus and the sinotubular junction. By restoring this continuity, the ATS 3f Aortic Bioprosthesis is the only aortic valve that preserves the sinuses and restores native valve stress distribution and physiologic blood flow. The ATS 3f Aortic Bioprosthesis design provides surgeons and patients with a potentially more durable solution to aortic valve replacement.

The mechanical heart valve segment will feature the flagship ATS Open Pivot(R) Heart Valve and its newest advancement, the ATS Open Pivot(R) AP360(TM) with enhanced surgical implant characteristics. The family of ATS mechanical heart valves features a unique open pivot design that results in exceptional hemodynamic performance and a low risk profile.

The ATS Simulus(R) Annuloplasty product line, designed for the heart valve repair market, will be showcased with special focus on the new ATS Simulus Semi-Rigid Annuloplasty Ring.

Exemplifying ATS's broad product offering is the ATS CryoMaze(R) Surgical Ablation System which is used to treat patients with cardiac arrhythmias. The ATS CryoMaze System provides results comparable to the gold standard cut-and-sew Cox Maze III procedure and is being used by a growing number of surgeons as their ablation technology of choice.

Hands-on demonstrations of all the unique technologies from ATS Medical will be available at the ATS Medical booth.

ATS Medical, Inc. is dedicated to "Advancing The Standards" of cardiac surgery through the development, manufacturing and marketing of innovative products and services for the treatment of structural heart disease. ATS Medical serves the cardiac surgery community by focusing on two distinct but operationally synergistic market segments: heart valve disease therapy and surgical ablation of cardiac arrhythmias.

ATS was originally founded to develop the ATS Open Pivot(R) Heart Valve as a new mechanical heart valve standard of care. Today the Open Pivot heart valve is the preferred mechanical heart valve in many markets around the world and the fastest growing mechanical prosthesis in the market. Building on this legacy and addressing the largest market segment in heart valve therapy, the ATS 3f(R) brand encompasses an innovative tissue heart valve portfolio to address conventional open surgery requirements as well as the growing demand for less invasive sutureless based procedures. The ATS 3f(R) portfolio includes offerings at various stages including early product development, pivotal clinical trials, and market commercialization. Completing the portfolio in heart valve therapy is the ATS Simulus(R) annuloplasty product line. Simulus products assist the surgeon in repairing a patient's native heart valve as an alternative to replacement. Continuing ATS Medical's focus on serving the cardiac surgery community are the ATS CryoMaze(TM) products for surgical cryoablation of cardiac arrhythmias. ATS CryoMaze(TM) products are used by surgeons to treat patients suffering from cardiac arrhythmias, the largest and fastest growing form of structural heart disease in populations over 60 years of age.
