ISSYS, Inc. Awarded a Patent for Wireless, Batteryless, Implantable Sensors

YPSILANTI, MI--(Marketwire - January 30, 2008) - Integrated Sensing Systems, Inc. (ISSYS) announced today that the U.S. Patent Office has granted a patent titled "Anchor for Medical Implant Placement and Method of Manufacture" (U.S. Patent No. 7,317,951) which covers the design and manufacturing of advanced, catheter-delivered, anchors for miniature, wireless, batteryless, implantable sensors within the heart for chronic, non-invasive monitoring of cardiovascular biological pressures.

Dr. Nader Najafi, ISSYS CEO, stated that "This patent is a major step towards the manifestation of ISSYS' technology as a viable medical product for effective monitoring of cardiovascular patients, in particular for congestive heart failure (CHF). ISSYS' miniature, implantable, wireless sensing technology distinguishes itself from other competitors by being the only current platform capable of monitoring the left side of the heart. Due to the shortcomings of their technologies, our competitors have focused on pulmonary artery cardiac pressure monitoring, which is better than no monitoring but not the desirable cardiac pressure waveform. The left atrium pressure (monitored by ISSYS' sensors) is the ideal signal for effective chronic treatment of CHF patients."

ISSYS' wireless, batteryless sensor and the anchor are delivered via a catheter in an outpatient procedure. The biocompatible anchor allows the miniature telemetric sensor to be stabilized within the heart and monitor the left atrium. This is a very difficult task due to the stringent biocompatibility requirements of the left heart. The anchor design allows the minimum size increase to the cylindrical wireless sensor and thus reduces the size of the delivery catheter. The novel anchor manufacturing renders highly reliable anchors demanded by chronic nature of cardiac sensors.
