Innovation: CardioMEMS EndoSure Sensor

CardioMEMS creates body sensors that monitor cardiovascular health
A TINY, DISEASE - FIGHTING SENSOR the EndoSure sensor pictured here is magnified 480 percent. the thin, looped wires anchor the device to artery walls.

Jay S. Yadav envisions a world in which wireless sensors implanted throughout the body constantly monitor a patient's cardiovascular health. He co-founded CardioMEMS in 2001, and the Atlanta company's first sensor, the EndoSure, is implanted in 5,000 patients suffering from aortic aneurysms. The sensor measures pressure inside the aorta and transmits data, via radio waves, to physicians during appointments a few times a year. Doctors use the data to tailor patients' drug regimens. Yadav, the company's CEO, says his ultimate goal is to adapt the technology to monitor patients with heart failure; these patients will take their pressure at home every day. The data will be stored online, and physicians will receive alerts if the numbers change. The heart-failure sensor is in clinical trials; Yadav expects it will receive FDA approval in 2010.
