Kensey Nash Announces Exclusive License of Optical Guidance Patent to Enhance Chronic Total Occlusio...( EXTON Pa. Nov. 2 /- Kensey Nash C...),Health

EXTON, Pa., Nov. 2 /PRNewswire-FirstCall/ -- Kensey Nash Corporation (Nasdaq: KNSY) today announced that it has exclusively licensed U.S. patent 6,175,669, Optical Coherence Domain Reflectometry Guidewire, from Lawrence Livermore National Security, LLC to further expand the intellectual property portfolio related to its chronic total occlusion (CTO) platform. The patent covers a guidewire with enhanced optical sensing capabilities, allowing it to sense locations, thickness, and structure of the arterial walls as it navigates through the body. The concept and technology, which are complimentary to Kensey Nash's Safe-Cross(R) RF CTO System, will allow the Company to develop next generation CTO devices with enhanced guidance and revascularization capabilities. The Safe-Cross System uses a forward-looking guidance system and radio frequency (RF) energy to safely cross and recanalize chronic total occlusions in the coronary and peripheral arteries. The terms of the license were not disclosed.

At the TransCatheter Therapeutics Conference (TCT) in Washington, D.C. last week, Dr. Charles Simonton, Carolinas Medical Center, performed a live case demonstrating the utility of the Safe-Cross System in crossing an in-stent restenosis CTO, greater than six months in age, in a patient's left anterior descending (LAD) coronary artery. The total crossing time was about fifteen minutes. Commenting on the Safe-Cross System and Kensey Nash's development plans for its platform, Dr. Simonton said, "The Safe-Cross System is unique as the only device for CTO lesions that incorporates optical feedback to provide guidance and radio frequency energy to penetrate difficult coronary occlusions. I am very pleased that Kensey Nash will be ref
