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 ...

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 tiny pacemaker sits next to a single grain of rice on a fingertip. The device is so small that it can be non-invasively injected into the body via a syringe. Northwestern University engineers have ...

In 2012, Neil Armstrong, the first human to walk on the moon, died from complications following heart surgery. His doctors had implanted a temporary pacemaker. When the pacemaker wires were later ...

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 ...

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 ...

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 ...
