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(TM) 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
