ATS Medical Announces US Launch of ATS CryoMaze Surgical Ablation Clamp

MINNEAPOLIS, Oct. 2 (HSMN NewsFeed) -- ATS Medical, Inc. (Nasdaq: ATSI ), manufacturer and marketer of state-of-the-art cardiac surgery products and services, today reported the US launch and first clinical uses of the ATS CryoMaze(TM) Surgical Ablation Clamp.

The launch of this product marks the first ablation product development effort by ATS since the product line was acquired from CryoCath Technologies. The ATS CryoMaze Clamp is similar in clinical use to other ablation clamps on the market; however, it is unique in that it uses argon-based cryoablation to create lesions rather than heat-based RF energy. The benefit of this ablation clamp over competitive devices is a unique ablation window that allows the surgeon to visually confirm complete freezing of the targeted tissue, providing confidence that the lesion has fully penetrated the tissue. The ablation window was developed by James L. Cox, MD, ATS Medical Director and a team of ATS engineers. Early prototype testing and evaluation was performed with the assistance of Evelio Rodriguez, MD of East Carolina University, who has also used the clamp in clinical practice.

"Some other ablation clamps must be applied multiple times and then tested to see if they work," said Dr. Rodriguez. "But with the ATS CryoMaze Clamp, you apply it once and, because you can see the frost coming through, you know that it worked with a single application."

The Company's ablation treatments have been predominantly performed as part of concomitant open-heart procedures. ATS anticipates the ATS CryoMaze Clamp will greatly expand its use in concomitant ablation during closed-heart procedures.

"Our success bringing the ATS CryoMaze Clamp into the marketplace underscores ATS Medical's innovative approach, focus on execution, and commitment to Advancing the Standard with devices and tools for the cardiac surgeon," commented Michael Dale, President and Chief Executive Officer of ATS Medical, Inc.
