The US Patent Office has granted Integrated Sensing Systems (ISSYS) US Patent No 7,860,579 B2, covering advanced methods for utilizing miniature, wireless, battery less, implantable sensors anchored within the heart, as well as other organs, for non-invasive monitoring of cardiovascular biological pressures.

ISSYS’ wireless, battery less, 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 left atrium pressure.

The company said the novel anchor manufacturing renders reliable anchors demanded by the chronic nature of cardiac sensors.

The miniature sensors can also be anchored in two other ways: open heart surgery, and minimally invasive surgery.

ISSYS CEO Nader Najafi said the particular targets of the company’s products are cardiovascular disease, especially congestive heart failure (CHF), hydrocephalus (high brain pressure), and traumatic brain injuries (TBI).

"ISSYS’ intellectual properties (patents, know how, and trade secrets) cover a wide spectrum including MEMS pressure sensors, the overall system, delivery and anchoring, and a variety of medical applications," Najafi said.
