AtriCure Receives FDA 510(k) Clearance for Multifunctional Isolator(TM) Transpolar (TM) Pen System and Releases New Isolator Transpolar Open Clamp

WEST CHESTER, Ohio, July 20 (HSMN NewsFeed) -- AtriCure, Inc. (Nasdaq: ATRC ), a medical device company focused on developing, manufacturing and selling innovative surgical devices, announced today that it has received Food and Drug Administration (FDA) 510(k) clearance for its Isolator Transpolar Pen System (Pen) for pacing, sensing, stimulating, and recording during the evaluation of cardiac arrhythmias in addition to its currently FDA- cleared use for the ablation of cardiac tissues. The AtriCure Pen is the only bipolar radiofrequency (RF) device that is cleared for this broad range of indications.

The new capabilities of this multifunctional Pen allow physicians to identify potential trigger areas on the heart that could cause cardiac arrhythmias. Additionally, physicians may ablate these targeted cardiac triggers and directly evaluate the effectiveness of the ablation, all with the same device. The multifunctional system includes specialized electrophysiology accessories that enable physicians to toggle between each function.

Separately, the Company announced the release of its new Isolator Transpolar open clamp, which leverages the design enhancements of the Isolator minimally invasive system released during the first quarter of 2006. This new open clamp features a design that improves the surgeon's access to key anatomical structures, simplifies the ablation procedure and provides superior tactile feedback to the user. The clamp currently has clearance from the FDA for the ablation of soft tissues in general, thoracic and other non-cardiac related surgical procedures.

Building on the foundation of success in more than 25,000 cases worldwide, the new open clamp utilizes AtriCure's proprietary, automated ablation algorithm and further reinforces AtriCure's market leadership position in surgical ablation devices. These devices deliver energy tailored to the biophysics of the tissue being ablated and are currently being evaluated in ongoing FDA clinical trials for the treatment of atrial fibrillation.

The first case with the new Isolator Transpolar System was conducted on June 28, 2006 by Patrick M. McCarthy, M.D., Chief, Division of Cardiothoracic Surgery at Northwestern Memorial Hospital in Chicago, IL. "My experiences with the new Isolator open clamp have been very encouraging. The new design makes the system easier to position around structures and the ablation lines are much more visible which assists in completing a successful ablation procedure," said Dr. McCarthy.

Dave Drachman, President and CEO, said, "The clearance of our multifunctional Pen and the release of our new open clamp represents our commitment to superior clinical outcomes through innovation. We believe the expanded indications for the Pen will drive adoption in both the open and minimally invasive markets, while the benefits of the new open clamp will further strengthen our market position. These innovative products represent important steps in our mission to improve human life through the treatment of patients who suffer from AF."
