Hansen Medical to Exhibit Magellan(TM) Robotic System at

MOUNTAIN VIEW, CA--(Marketwired - May 23, 2013) -  Hansen Medical, Inc. ( NASDAQ : HNSN ), a global leader in intravascular robotics, today announced that it will exhibit its Magellan™ Robotic System at the 2013 Vascular Annual Meeting ^® of the Society for Vascular Surgery from May 30 - June 1 at the Moscone West Convention Center in San Francisco, CA. The Company will be exhibiting the Magellan Robotic System and conducting product demonstrations at Booth 301.

"We are excited to showcase our Magellan Robotic System at this important annual meeting of leading vascular surgeons," said Bruce Barclay, President and CEO of Hansen Medical. "Based on the over 150 vascular cases that have now been performed to date, as well as the feedback received from clinicians worldwide and the extensive pre-clinical work previously completed, we are confident that this product has the potential to enhance the way physicians navigate the vasculature. The Magellan Robotic System and Catheter give physicians maximum flexibility and control through independent distal tip control of a catheter and a sheath, as well as through robotic manipulation of a standard guidewire from a centralized, remote workstation. Moreover, this proprietary technology is designed to deliver predictable catheter navigation of peripheral vessels."

About the Magellan™ Robotic System

Hansen Medical's Magellan Robotic System is based upon the flexible robotic technology incorporated in the Sensei-X® Robotic Catheter System currently sold in the U.S. and Europe, which has been used in over 10,000 patients, but includes a number of key enhancements. In particular, the Magellan Robotic System:

• Provides solid catheter stability for placement of therapeutic devices.
• Is designed to enable predictable procedure times and increased case throughput.
• Allows for independent, individual robotic control of the distal tips of both the outer sheath and the inner leader catheter, as well as robotic manipulation of standard guidewires.
• Is designed to allow for sufficient extension inside the body to access hard to reach peripheral anatomy.
• Preserves the open architecture featured in the Sensei System to allow for the subsequent use of many 6F therapeutic devices on the market today.
• Is designed to potentially reduce physician radiation exposure and fatigue by employing a remote physician workstation.

About Hansen Medical, Inc.

Hansen Medical, Inc., based in Mountain View, California, is the global leader in intravascular robotics, developing products and technology designed to enable the accurate positioning, manipulation and control of catheters and catheter-based technologies. The Company's Magellan™ Robotic System, NorthStar™ 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 both CE marking and 510(k) clearance and are commercially available in the European Union, and the U.S. In the European Union, the Company's Sensei® X Robotic Catheter System and Artisan Control Catheter are cleared for use during electrophysiology (EP) procedures, such as guiding catheters in the treatment of atrial fibrillation (AF), and the Lynx® Robotic Ablation Catheter is cleared for the treatment of AF. This robotic catheter system is compatible with fluoroscopy, ultrasound, 3D surface map and patient electrocardiogram data. In the U.S. the Company's Sensei X Robotic Catheter System and Artisan Control Catheter were cleared by the U.S. Food and Drug Administration for manipulation and control of certain mapping catheters in EP procedures. In the United States, the Sensei 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 X System and Artisan Control Catheter for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including AF, have not been established.
