MRI no longer off limits for pacemakers

JOHNS HOPKINS (US) — Patients with cardiac implants can safely undergo MRI scans if their doctors follow new guidelines, researchers say. MRI—or magnetic resonance imaging—has been off limits to more...

Pacemaker powered by heart’s vibration

U. MICHIGAN (US) — Engineers have designed a cardiac pacemaker that is powered by vibrations from the patient’s heartbeat. Engineering researchers at the University of Michigan designed a device that...

Fix heart RHYTHM WITH LIGHT, NOT JOLTS

Electric shocks used to restore an irregular heart to a regular beat may soon be replaced by light—a kinder, gentler treatment, researchers say. Jolts of current from a pacemaker or defibrillator can...

Pacemakers of the future: No batteries required?

Tiny power generators that convert the motion of a beating heart into electrical energy could eliminate the need for batteries in pacemakers and other medical devices. As reported in Proceedings of the...

Wireless pacemaker is much smaller than a penny

Engineers have built an electronic pacemaker that’s smaller than a grain of rice and can be powered or recharged wirelessly by holding a power source about the size of a credit card above the device,...
