MINNEAPOLIS, April 30 /PRNewswire-FirstCall/ -- ATS Medical, Inc. (Nasdaq: ATSI), manufacturer and marketer of state-of-the-art cardiac surgery products and services, today announced the first Frontiers in Cryoablation Symposium to be held at the American Association for Thoracic Surgery Annual Meeting in San Diego.

Cox, inventor of the Maze procedure and Medical Director for ATS Medical, will lead the symposia series.

This first symposium, titled "Current Techniques, Robotics and the Future of Minimally Invasive Cryoablation" is sponsored collaboratively by ATS Medical and Intuitive Surgical, the makers of the da Vinci(R) Surgical System (Nasdaq: ISRG). The symposium follows the recent market release of Intuitive Surgical's Endowrist Cardiac Probe Grasper -- a device specifically designed to assist the da Vinci System in manipulating ATS CryoMaze Surgical Ablation Probes to complete the Cox Maze III procedure. The Symposium will be conducted on Sunday, May 11 at 7:00 pm.

"The Frontiers in Cryoablation Series will provide a forum for presenting the current capabilities of surgical cryoablation and allow physicians to collaborate on the future of minimally invasive techniques for the treatment of atrial fibrillation. I am excited about the opportunity to expand the application of cryoablation using minimal access and stand-alone procedures to maximize the benefit for surgeons and their patients," stated Dr. James Cox, Medical Director for ATS Medical.

The treatment of atrial fibrillation (AF) is believed to be the largest untapped opportunity in medical devices with an estimated multi-billion dollar market potential. In contrast, the current surgical market size is estimated at $121 million in 2007. Based on initial clinical results, management believes that only ATS has the technology -- the ATS CryoMaze Surgical Ablation System -- proven to yield clinical results similar to the conventional cut-and-sew Cox Maze III procedure, but with an approach involving small incisions. As such, the surgical AF business is expected to be a key growth opportunity for ATS in 2008 and beyond.
