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

Ypsilanti, Michigan: Integrated Sensing Systems, Inc. (ISSYS) announced that the U.S Patent Office has granted a patent entitled "Method and Anchor for Medical Implant Placement and Method of Anchor Manufacture" (US Patent No. 7,634,319) which covers the methods for utilizing miniature, wireless, batteryless, implantable sensors anchored within the heart for non-invasive monitoring of cardiovascular biological pressures.

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 pressure. 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 the chronic nature of cardiac sensors.

Dr. Nader Najafi, ISSYS CEO, stated that "The particular targets of ISSYS products are cardiovascular disease, especially congestive heart failure (CHF), hydrocephalus (high brain pressure), and traumatic brain injuries (TBI). ISSYS' technology distinguishes itself from other competitors by being the only viable miniature, wireless, implantable sensor platform capable of monitoring the left side of the heart. The left atrium pressure (monitored by ISSYS' sensors) is the ideal signal for effective chronic treatment of CHF patients"
