Medical Device Combines Wireless And Mems Technology

Winning a thumbs-up from the U.S. Food and Drug Administration, CardioMEMS Inc. has launched its EndoSure- sensor, which makes testing safer and more convenient for aneurysm patients.

Based on intellectual property from the Georgia Institute of Technology, EndoSure is the first implantable pressure sensor that combines wireless and microelectromechanical system (MEMS) technology to receive FDA clearance.

"This is a significant milestone that validates our product is safe and relevant," says David Stern, CardioMEMS' chief executive, noting that the FDA based its 510(k) clearance on results from an international clinical study involving more than 100 hospital patients in the United States as well as Brazil, Argentina and Canada.

Better results, less hassle.

Officially known as the EndoSure Wireless AAA Pressure Measurement System, CardioMEMs' innovative device measures blood pressure in people who have an abdominal aortic aneurysm. Ruptures from this weakening of the lower aorta rank as the 13th leading cause of death in the United States. Although doctors can treat the bulging artery with a stent graft, stents can fail, so aneurysm patients require lifetime monitoring.

Yet traditional testing methods, such as CT scans, are expensive and time-consuming. What's more, CT scans are limited in scope because they only reveal the size of an aneurysm. In contrast, the EndoSure monitors pressure inside the aneurysm sac - the most important measurement for doctors to know.

CardioMEMS also makes testing easier for both doctors and patients. About the size of a paper clip, the EndoSure sensor is implanted along with the stent graft during endovascular repair. During checkups, patients don't need to remove clothing: Doctors merely wave an antenna in front of the patient's chest, and low-power radio-frequency waves activate the EndoSure system, relaying pressure measurements to an external receiver and monitor.
