ATS Medical Announces First Use of the New ATS CryoMaze 10-S Probe

MINNEAPOLIS, July 20 (Healthcare Sales & Marketing Network) -- ATS Medical, Inc. (Nasdaq: ATSI ), manufacturer and marketer of state-of-the-art cardiac surgery products and services, today announced the first commercial use of the new ATS CryoMaze(TM) 10-S Surgical cryoablation Probe for the treatment of cardiac arrhythmias. The cryoablation procedure was performed by Niv Ad, MD, Chief of Cardiac Surgery at the Inova Heart & Vascular Institute in Falls Church, Virginia, a premier heart center in the United States.

The ATS CryoMaze 10-S Probe complements the current product offering by adding a linear cryoablation probe that is more rigid than the current ATS CryoMaze Probes. The increased support throughout the length of the 10-S probe addresses the preference of some surgeons to have more probe leverage to achieve contact with targeted tissue that is difficult to reach. In addition, the increased stiffness of the ATS CryoMaze 10-S Probe will optimize the shape retention of the malleable probe which is particularly useful in minimally invasive procedures.

The new cryoablation probe leverages the second generation, argon-based ATS CryoMaze System that quickly achieves the coldest probe temperatures available for cardiac arrhythmia surgery. The argon-based cryoablation system routinely reaches probe temperatures of -160 degrees C compared to first generation nitrous-oxide systems that only reach temperatures of -65 degrees C. The colder probe temperatures provide faster, deeper lesions yielding greater confidence that transmural, linear lesions are being achieved, especially in clinical situations in which varying tissue thickness is the rule.

The proprietary design utilized in all ATS CryoMaze Probes allows them to be easily shaped by hand without the need for a tool to control the radius of the bends. The probe tip can be repeatedly re-shaped intraoperatively to meet the different anatomic requirements of the individual patient and procedure. The "bellows" design of the ATS CryoMaze Probes facilitates this durable probe malleability without kinking and/or fractures.

"The ATS CryoMaze System is very well equipped for minimally invasive stand-alone surgery for atrial fibrillation. The new, more rigid 10-S probe is a great addition that makes it easier to apply lesions and complete full biatrial Maze-III procedures," said Dr. Ad.

"The ATS CryoMaze 10-S Probe is another example of ATS Medical's commitment to cardiac surgery and the cardiac arrhythmia market. We are driving innovation in this segment to improve ease of use and decrease procedure times. Under guidance of our ATS cryoablation Surgical Advisory Board, we will continue to advocate complete, biatrial Maze-III lesion sets to achieve the best possible patient outcomes. The surgical approach continues to demonstrate excellent clinical outcomes in treating cardiac arrhythmias," said Michael Dale, President and CEO of ATS Medical.

About ATS Medical

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®( )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® 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® 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® 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.
