Texas Cardiac Arrhythmia Institute at St. David's Medical Center First in the Nation to Use a New Generation of Medical Robots for Complex Electrophysiology Mapping Procedures

CoHesion(TM) 3D Visualization Module Improves Physician Accuracy And

Reduces Radiation Exposure for Patients

AUSTIN, Texas, Aug. 13 /PRNewswire/ -- This week, doctors at the Texas Cardiac Arrhythmia Institute (TCAI) at St. David's Medical Center became the first in the nation to implement the CoHesion(TM) 3D Visualization Module -- an enhancement to the state-of-the art Hansen Robotic system used to treat cardiac arrhythmias. With the visualization module, patients undergoing the ablation treatment for heart arrhythmias are exposed to about 30 percent less radiation than without the new technology, among other benefits.

Heart arrhythmias are problems that affect the electrical system, or "wiring," of the heart muscle. Heart arrhythmias are very common. Experts say that millions of people will experience an abnormal heart rhythm some time during their lives.

During cardiac ablation, doctors destroy, or ablate, a small spot of heart tissue to create an electrical block along the pathway that causes a heart arrhythmia. The new CoHesion(TM) module can help reduce potentially fatal complications during treatment. The improved accuracy of allowing physicians to more precisely control the robotic catheter can also reduce the time it takes to perform the procedure, cutting the amount of radiation exposure for patients by about 30 percent.

The new CoHesion(TM) module combines the EnSite System's 3D cardiac chamber model with anatomic labeling with the Sensei system's main navigation window, allowing physicians to see the location of Hansen Medical's Artisan(TM) Control Catheters within the heart in 3D. This allows doctors to augment their ability to move a catheter throughout the heart, as well as increase control over placement of the catheter in specific locations in patients with heart arrhythmias. Previously, physicians used 3D imaging as a reference only.

Hansen Medical, Inc. received FDA approval for using the CoHesion(TM) 3D Visualization Module in complex electrophysiology mapping procedures in July, 2008.

TCAI -- an international treatment, training and research center specializing in heart rhythm disorders -- formally opened in April, 2008, under the direction of internationally renowned cardiac electrophysiologist Andrea Natale, M.D.
