Because the human heart requires only a small amount of electrical stimulation, researchers were able to shrink their ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can ...

Developed by engineers from Northwestern University, the pacemaker is the size of a grain of rice and could help save babies ...

Temporary pacemaker can be injected, fits any size patient, including babies, and eliminates need to remove it.

When the pacemaker wires were later removed, Armstrong suffered internal bleeding — an outcome more common than many patients realize. Now, engineers at Northwestern University have developed what ...

A light-activated pacemaker dissolves in the body after use, offering safer, wireless heart care - especially for newborns ...

A tiny device can be inserted using a syringe and then safely dissolves once it is no longer needed. Engineers at Northwestern University have developed an ultra-small pacemaker that is so tiny it can ...

Although it can work with hearts of all sizes, the pacemaker is particularly well-suited to the tiny, fragile hearts of ...

The new device is smaller than a grain of rice and gets absorbed by the patient’s body when it’s no longer needed, ...

Though the device is still years away from being used in humans, it could eventually be useful for infants with congenital ...

So far, the pacemaker has worked effectively in tests on mice, rats, pigs, dogs and human heart tissue in the lab, according to the study. Senior study author John Rogers of Northwestern ...

It’s been successfully tested in rat, pig, dog, and human hearts ... where signals from one part of the heart don’t reach another. These embedded pacemakers can kick in automatically to ...
