HNSN Hansen Medical, Inc. (MM)

Booth # 401 -- Hansen Medical, Inc. (NASDAQ: HNSN) will showcase its Sensei๏ฟฝ Robotic Catheter System and the CoHesion(TM) 3-D Visualization Module here at the 14th Annual Boston Atrial Fibrillation Symposium, Jan. 15-17, 2009. The integrated electrophysiology (EP) solution offers physicians a software interface between Hansen Medical's robotic catheter system and St. Jude Medical's EnSite(TM) System advanced mapping technology. It is designed to provide physicians with 3-D visualization to enhance their ability to move a catheter throughout the heart and is intended to optimize control over catheter placement in specific locations.

"It is our goal to continue to offer physicians technological solutions that provide confidence and accuracy during complex procedures," said Gary Restani, president and COO of Hansen Medical. "Clinicians using the Sensei system and the integrated 3-D visualization module report confidence in catheter placement and navigation, as well as a reduction in fluoroscopy time.

"We are very encouraged by the broad adoption of our technology worldwide with 55 systems shipped through 2008 and well over 1,000 clinical cases reported using the Sensei system, many of which have been completed using our integrated solution," continued Restani.

The CoHesion interface expands the utility of the EnSite System and Sensei systems to provide physicians with a comprehensive and easy-to-use remote navigation and mapping system for EP procedures. The EnSite system provides visualization and localization for detection of EP catheters in 3-D space within the heart chamber, while the Sensei system is designed to permit remote movement of catheters in 3-D. By integrating both products, Hansen Medical believes physicians should be able to navigate more instinctively within the 3-D cardiac space because the system enables visualization and catheter movement in 3-D.

"The Sensei system with the CoHesion interface is truly innovative because it allows for very accurate catheter manipulation and catheter stability," said Patrick Hranitzky, M.D., assistant professor of medicine and director of Clinical Cardiac Electrophysiology at Duke University Medical Center in Durham, N.C.

"In addition, the ability to perform complex and potentially long procedures while seated at the workstation without wearing the heavy lead could lead to greater career longevity for clinicians. Therefore, I prefer the Sensei system for all of my complex cardiac procedures," continued Dr. Hranitzky.

St. Jude Medical's EnSite System is an advanced computer-based technology for mapping the electric activity for the heart, and for localizing and visualizing EP catheters in real-time. The EnSite System creates 3-D graphical displays of cardiac structures and arrhythmias, and enables catheter navigation without the use of fluoroscopy.

The Sensei system uses flexible medical robotics technology to provide stable and predictable control of catheter movement inside the heart. This innovative technology is designed to provide fine catheter control while mapping in 3-D to enhance the physician's ability to access hard-to-reach anatomy, and to maintain stability during complex cardiac arrhythmia procedures. The physician workstation is adaptable to existing EP lab suites and can be placed away from the field of direct radiation. The disposable Artisan(TM) Control Catheter is comprised of inner and outer steerable guide catheters that accommodate existing pre-approved percutaneous catheters. And, with the IntelliSense๏ฟฝ Fine Force Technology, clinicians have access to real-time measurement and display of the proximal force along the shaft of percutaneous catheters.

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 compatible with fluoroscopy, ultrasound, 3-D 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. The Sensei system is CE Marked for use during EP procedures, such as guiding catheters in the treatment of AF. Additional information can be found at www.hansenmedical.com.
