About Hansen Medical, Inc.

Hansen Medical Inc., based in Mountain View, Calif., develops products and technology using robotics for the accurate positioning, manipulation and control of catheters and catheter-based technologies. Its first product, the Sensei® Robotic Catheter system, is a robotic navigation system that enables clinicians to place mapping catheters in hard-to-reach anatomical locations within the heart easily, accurately and with stability during complex cardiac arrhythmia procedures. The Sensei system is compatible with fluoroscopy, ultrasound, 3D surface map and patient electrocardiogram data and was cleared by the U.S. Food and Drug Administration (FDA) in May 2007 for manipulation and control of certain mapping catheters in Electrophysiology (EP) procedures. The safety and effectiveness of the Sensei system 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 system is cleared for use during EP procedures, such as guiding catheters in the treatment of AF. Additional information can be found at www.hansenmedical.com.
