HNSN Hansen Medical, Inc. (MM)

Hansen Medical, Inc. (NASDAQ: HNSN), the global leader in flexible medical robotics and the developer of robotic technology for accurate 3D control of catheter movement, will showcase its Sensei® X Robotic Catheter System and the Artisan Extend(TM) Control Catheter at the 15th Annual Boston Atrial Fibrillation Symposium, Jan. 14-16, 2010 (Booth 210). In addition, the company will highlight its Lynx(TM) Robotic Ablation Catheter, a small, flexible irrigated ablation catheter that will be available to customers in Europe following CE Mark approval.

"We are very encouraged by the positive response to our new flexible robotics platform in such a short period of time following its launch in September 2009," said Frederic Moll, M.D., president and CEO, Hansen Medical. "Hansen Medical remains steadfast in its commitment to developing innovative technological solutions that address the clinical needs of electrophysiologists by extending the procedural capabilities of robotic catheter control during EP procedures."

The Sensei X system is the next generation flexible robotic platform that integrates advanced levels of 3D catheter control with 3D visualization, providing enhanced accuracy and stability to physicians during complex cardiac arrhythmia procedures. The Sensei X platform supports the Artisan Extend control catheter, which increases the reachability and navigation properties of the Artisan catheter by offering more than 20 percent improvement in both bend and reach. As a result, physicians have the ability to place catheters deliberately and accurately within the heart. In addition, the Artisan Extend catheter offers improvements in setup and workflow, and is designed to improve usability and reduce procedure time.

"The new robotic platform enables us to navigate and control the catheter in 3D with greater stability and enhanced responsiveness, which improves our ability to perform successful complex arrhythmia mapping procedures safely," said Rahul N. Doshi, Director, Arrhythmia Services and Chair, Cardiothoracic, St. Jude Medical Center, Fullerton, Calif. "In addition, we are experiencing a reduction in fluoroscopy time and radiation dosage during flexible robotic procedures.

"During our initial evaluation of the Artisan Extend catheter, we found that the improved flexibility and bend radius allowed access to anatomic targets that are typically hard to reach when using manual technique. In addition, setup for the Artisan Extend was simplified, so our procedure time was reduced," continued Dr. Doshi.

The Sensei X platform also supports Hansen Medical's CoHesion(TM) 3D Visualization Module, which integrates the 3D motion control of the Sensei X system with the 3D visualization of the St. Jude Medical EnSite(TM) system. Two features of the Sensei X system designed to improve procedural planning and workflow include Workspace Visualization, an enhancement that allows physicians to see the catheter's reach on a 3D map prior to navigation, and EndoView, a feature that allows physicians to quickly change the orientation to a standard endoscopic view.

The Lynx robotic ablation catheter will also be supported by the Sensei X platform and will leverage the navigation capability of the Artisan Extend catheter, but in a smaller and more flexible integrated profile for the treatment of Atrial Fibrillation (AF) and other electrophysiology disorders. The Lynx catheter is pending CE Mark approval and is expected to be available in the European Union in the first half of 2010.

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.
