Hansen Medical Announces Worldwide Survey of AF Ablation with Robotic Navigation Presented at American Heart Association

Hansen Medical, Inc., based in Mountain View, California, develops products and technology using robotics for the accurate positioning, manipulation and control of catheters and catheter-based technologies. The Company's Sensei(R) X Robotic Catheter System and Artisan(R) Control Catheter were cleared by the U.S. Food and Drug Administration for manipulation and control of certain mapping catheters in electrophysiology (EP) procedures. This robotic catheter system is compatible with fluoroscopy, ultrasound, 3D surface map and patient electrocardiogram data. In the United States, the Sensei(R) System is not approved for use in guiding ablation procedures; this use remains experimental. The U.S. product labeling therefore provides that the safety and effectiveness of the Sensei(R) X System and Artisan(R) Control Catheter for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including atrial fibrillation (AF), have not been established. In the European Union, the Sensei(R) X System and Artisan(R) Control Catheter are cleared for use during EP procedures, such as guiding catheters in the treatment of AF, and the Lynx(R) Robotic Ablation Catheter is cleared for the treatment of AF. The Company's Magellan(TM) Robotic System, NorthStar(TM) Robotic Catheter and related accessories, which are intended to facilitate navigation to anatomical targets in the peripheral vasculature and subsequently provide a conduit for manual placement of therapeutic devices, have undergone conformity assessment and CE marking and are commercially available in the European Union.

In the U.S., the Magellan(TM) Robotic System, the NorthStar(TM) Robotic Catheter and accessories are the subject of a pending 510(k) with the FDA and are not commercially available. Additional information can be found at http://www.hansenmedical.com.
