Heart-Powered Leadless Pacemaker in Development
28 October 2015. A heart pacemaker — the device regulating heartbeats of people with slow or irregular heart rhythms — is being designed to draw power from the beating heart itself and work with next-generation devices that operate inside the heart without wires or leads. Engineers from University at Buffalo in New York, in the…
