Wireless, fully implantable device gives temporary pacing without requiring removal. Researchers at Northwestern and George Washington (GW) universities have developed the first-ever transient pacemaker — a wireless, battery-free, fully implantable pacing device that disappears after it’s no longer needed.

The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components of the pacemaker are biocompatible and naturally absorb into the body’s biofluids over the course of five to seven weeks, without needing surgical extraction.

The device wirelessly harvests energy from an e...

Transforming super-sensitive touch sensors, engineers and medical researchers build a way to wirelessly monitor blood flow after surgery. It is biodegradable, battery-free and wireless, so it is compact and doesn’t need to be removed and it can warn a patient’s doctor if there is a blockage.

“Measurement of blood flow is critical in many medical specialties, so a wireless biodegradable sensor could impact multiple fields including vascular, transplant, reconstructive and cardiac surgery,” said Paige Fox, assistant professor of surgery and co-senior author of the paper...

The pacemaker can be inserted into the heart and powered by a battery pack outside the body, eliminating the need for wire leads and surgeries to occasionally replace the battery.

Researchers test microwave-powered device. A wireless, battery-less pacemaker that can be implanted directly into a patient’s heart is being introduced by researchers from Rice University and their colleagues at the Texas Heart Institute (THI) at the IEEE’s International Microwave Symposium (IMS) in Honolulu June 4-9...
