Hansen Medical to showcase integrated 3D electrophysiology solution at Boston Atrial Fibrillation Symposium

Boston 17 January 2008Hansen Medical Inc. has showcased its new Cohesion 3D Visualization Interface alongside its Sensei Robotic Catheter System at the recently held 13th Annual Boston Atrial Fibrillation (AF) Symposium. The newly integrated electrophysiology (EP) solution offers physicians a software interface between the company's next generation robotic technology and the St. Jude Medical EnSite System. Although the CoHesion Interface is already commercially available in the European Union, it is currently undergoing 510(k) review by the United States Food and Drug Administration (FDA), and is not yet commercially available in the United States.


The CoHesion Interface is designed to allow physicians to remotely manipulate catheters with more accuracy because it provides 3D information regarding the actual position of catheters inside a patient's heart. These features are expected to make complex EP procedures more efficient by enabling physicians to operate in a 3D navigation and mapping environment with robotic control over catheter placement in specific locations.

"This integrated platform solution is another step in our ongoing strategy to expand our offering to electrophysiologists worldwide and position Hansen Medical at the forefront of finding solutions to help physicians benefit their patients by effectively and safely treating heart disease earlier", stated Frederic Moll, M.D., founder and CEO of Hansen Medical. "By integrating our Sensei system with St. Jude Medical's EnSite system, we are augmenting the ability of electrophysiologists to more easily move catheters within the 3D cardiac space so they can perform complex procedures with more confidence."

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

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 electrophysiology catheters in real time. The EnSite system creates 3D graphical displays of cardiac structures and arrhythmias, and enables catheter navigation without the use of fluoroscopy. Additionally, the EnSite system's open platform allows physicians to use their preferred therapy approach with diagnostic and ablation catheters of their choice.

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 3D to enhance the physician's ability to access hard-to-reach anatomy, and to maintain stability during interventional procedures. The physician workstation is adaptable to existing EP procedure rooms and can be placed away from the field of direct radiation. The disposable Artisan Control Catheter is comprised of inner and outer steerable guide catheters that accommodate existing pre-approved percutaneous catheters.

Hansen Medical, based in Mountain View, California, was founded in 2002 to develop 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 cleared by the FDA for manipulation and control of certain mapping catheters in electrophysiology procedures. The safety and effectiveness of the Sensei system for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including atrial fibrillation, have not been established.
