A pacemaker is a small, battery-powered device that controls the heartbeat. Our heartbeats are controlled by a highly efficient, biological electrical system that ensures our heart steadily pumps ...

Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe—and be noninvasively injected into the body. Although it can work with hearts of all ...

Heartbeats could one day help power something beyond hearts. A pacemaker is a device that helps regulate abnormal heart rates using electrical pulses. Leadless pacemakers, which are placed in the ...

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible ...

An experimental leadless pacemaker is able to capture enough energy from the heart to partially power the device, according to results from a new proof-of-concept study. The prototype device harvested ...

Wireless or leadless pacemakers, commonly implanted in adults, may be a safe and effective short-term option for children with slow heartbeats, according to new research published today in Circulation ...
