STJ ST. Jude Medical, Inc.

St. Jude Medical, Inc. (NYSE:STJ) today announced expanded European CE Mark approval to include the Therapy� Cool Path� irrigated ablation catheter with bi-directional steering for use in ablation procedures to treat abnormal heart rhythms. This catheter is the first open-irrigated ablation catheter to provide bi-directional steering, a feature designed to help physicians maneuver the catheter in difficult areas of the heart and perform complex ablations more efficiently. �The main advantage of the bi-directional catheter is its ease of use in reaching difficult anatomical locations,� said Carlo Pappone, M.D., Ph.D., F.A.C.C., director of the Arrhythmology Department at San Raffaele University Hospital in Milan. �Because the catheter requires less manipulation and provides for greater simplicity of navigation, my procedural time was improved by about 20 percent.� �We are excited to offer physicians the first bi-directional, open-irrigated catheter in the European market,� said Peter Chen, president of Irvine Biomedical, Inc., a St. Jude Medical Company. �As the population ages, the demand for more effective treatment of cardiac arrhythmias will only increase.� St. Jude Medical also announced U.S. Food and Drug Administration (FDA) approval and release of the uni-directional Therapy� Cool Path� open-irrigated ablation catheter for use in patients with type 1 atrial flutter. With atrial flutter, the heart�s upper chambers beat steadily faster than normal, often resulting in a feeling of lightheadedness. Catheter ablation therapy is used by physicians to restore a normal heart rhythm in patients with cardiac arrhythmias. During the procedure, an electrophysiologist uses a catheter (a long narrow tube) to deliver radiofrequency energy to create lesions in specific areas of cardiac tissue. The lesions, or tiny scars, interrupt the abnormal electrical signals that contribute to erratic heart rhythms. An open-irrigated catheter distributes saline fluid into heart tissue through ports in the tip of the catheter to enhance cooling during ablation procedures. Cooling the tip of the catheter is designed to reduce the risk of undesirable tissue damage at the procedure site. Studies have shown that open-irrigated catheters safely and effectively create deeper and larger lesions while using less energy than standard therapy catheters. "We are pleased to expand and enhance our U.S. electrophysiology portfolio," said Michael T. Rousseau, president of St. Jude Medical's U.S. Division. "These products broaden St. Jude Medical's EP catheter and ablation system offerings, reflecting the Company's commitment to develop industry-leading technologies for treating many cardiac arrhythmias." St. Jude Medical�s electrophysiology offerings include introducers, diagnostic catheters and cardiac mapping systems. The Therapy Cool Path irrigated catheters work in conjunction with St. Jude Medical�s EnSite� System, a computer-based visualization technology that provides physicians three-dimensional graphical images of the heart and the location of the arrhythmia's origin, enabling them to navigate electrophysiology catheters in real time. About St. Jude Medical St. Jude Medical is dedicated to making life better for cardiac, neurological and chronic pain patients worldwide through excellence in medical device technology and services. The Company has five major focus areas that include: cardiac rhythm management, atrial fibrillation, cardiac surgery, cardiology and neuromodulation.�Headquartered in St. Paul, Minn., St. Jude Medical employs more than 11,000 people worldwide.
