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.
