Hansen Medical Announces Publication of Uterine Artery Embolization (UAE) Results

Publication States UAE Procedures Are Feasible and Appear to Be Safe With Magellan(TM) Robotic System

MOUNTAIN VIEW, CA -- (Marketwired) -- 07/29/14 -- Hansen Medical, Inc. (NASDAQ: HNSN) -- A study, published online in the Journal of Vascular Interventional Radiology, found the use of the Magellan Robotic System in uterine artery embolization, or "UAE", procedures is feasible and appears to be safe. Researchers reviewed the results of five patients treated with robot-assisted UAE over a 10 month period at St. Mary's Hospital, Imperial College London. Lead Investigator Dr. Mohammad Hamady and his colleagues conducted the study to investigate the safety and feasibility of the Magellan 9Fr Robotic Catheter in this complex arterial bed.

All procedures were successfully completed without local puncture site complications or access vessel injuries. Further, robotic bilateral internal iliac artery cannulation was successfully performed in all cases. At the six-month follow-up mark, all patients reported significant improvement in symptoms and quality-of-life.

"We are very pleased with the results of the Magellan Robotic System in UAE procedures, and appreciate the work of the investigators at Imperial College London," said Cary Vance, President and CEO of Hansen Medical. "The findings from this study highlight the potential in women's health, and we expect that a broad group of patients will be able to benefit from robot assisted embolization procedures."

Uterine fibroids are tumors that grow in a woman's womb. They are the most common benign tumors in women and the leading cause for hysterectomies in the US. As many as 1 in 5 women may have fibroids during their childbearing years. Half of all women have fibroids by age 50. Uterine artery embolization is a minimally-invasive treatment option for uterine fibroids in which a catheter is used to deliver small particles into the uterine artery to stop blood flow to the fibroids.

"This study provides an initial foundation for this clinical application of intravascular robotics," said Dr. Hamady, Imperial College London. "The use of robotic catheters in UAE procedures offer several potential benefits. Fine adjustments can be made to the catheter tip, which may improve predictability of navigation in complex anatomy."

About the Magellan™ Robotic System
Hansen Medical's (NASDAQ: HNSN) Magellan Robotic System is intended to be used to facilitate navigation in the peripheral vasculature and subsequently provide a conduit for manual placement of therapeutic devices. The Magellan Robotic System is designed to deliver improved predictability, control and catheter stability to endovascular procedures. Since its commercial introduction in the U.S. and Europe, the Magellan Robotic System has demonstrated its clinical versatility in many cases in a broad variety of peripheral vascular procedure types in centers across the U.S. and Europe. The Magellan Robotic System offers several important features including:

  • Provides predictability, control and catheter stability as a physician navigates a patient's peripheral vasculature and then provides a conduit for manual treatment of vascular disease with standard therapeutic devices.
  • Is designed to enable more predictable procedure times and increased case throughput potentially allowing hospitals to improve utilization within their vascular business line
  • Employs an open architecture designed to allow for the subsequent use of many therapeutic devices on the market today.
  • Is designed to potentially reduce physician radiation exposure and fatigue by allowing the physician to navigate procedures while seated comfortably at a remote workstation away from the radiation field and without wearing heavy lead as required in conventional endovascular procedures.
  • The Magellan 9Fr Robotic Catheter allows for independent, robotic control of the distal tip of two telescoping catheters (an outer Guide and an inner Leader catheter), as well as robotic manipulation of standard guidewires.
  • The Magellan 6Fr Robotic Catheter allows for independent robotic control of two separate bend sites on a single catheter, as well as robotic manipulation of standard guidewires. This smaller catheter design may be preferred by certain physicians who prefer a smaller diameter vessel access site, or in procedures in smaller vessels.

About Hansen Medical, Inc.
Hansen Medical, Inc., based in Mountain View, California, is a 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, 9Fr Magellan™ Robotic Catheter, Magellan™ 6Fr Robotic Catheter, and related accessories are intended to facilitate navigation to anatomical targets in the peripheral vasculature and subsequently provide a conduit for manual placement of therapeutic devices. The Magellan 9Fr Robotic Catheter has undergone both CE marking and 510(k) clearance and is commercially available in the European Union, and the U.S. The Magellan 6Fr Robotic Catheter has undergone 510(k) clearance in the U.S. and is in limited release for the next several months in anticipation of more wide-scale commercially availability later in 2014. In the European Union, the Company's Sensei® X Robotic Catheter System and Artisan® and Artisan Extend® Control Catheters 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 and Artisan Extend Control Catheters are cleared by the U.S. Food and Drug Administration for manipulation and control of certain mapping catheters in EP procedures. In the U.S., the Sensei X Robotic Catheter 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 Robotic Catheter System and Artisan and Artisan Extend Control Catheter for use with cardiac ablation catheters in the treatment of cardiac arrhythmias, including AF, have not been established.
