Researchers at Northwestern University just found a way to make a temporary pacemaker that’s controlled by light—and it’s smaller than a grain of rice. A study on the new device, published last week ...

The world’s tiniest pacemaker — smaller than a grain of rice — could help save babies born with heart defects, say scientists. The miniature device can be inserted with a syringe and dissolves after ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can become a race against time to restore balance. For decades, doctors have ...

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 ...

Procedure-related infection rates were similar to reconditioned and new pacemakers, according to late-breaking research presented in a Hot Line session at the ESC Congress 2025. Subscribe to our ...

When Aurora Ernzen was just 5 days old, doctors performed surgery to insert a pacemaker in her chest. The device was new, permitted through emergency use guidelines from the U.S. Food and Drug ...

Tiny device can be inserted with a syringe, then dissolves after it's no longer needed. (Nanowerk News) Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the ...

Though a Northwestern-developed quarter-size dissolvable pacemaker worked well in pre-clinical animal studies, cardiac surgeons asked if it was possible to make the device smaller. To reduce the size ...
