Pacemakers are vital, life-saving technology held back by their limited battery life, but the solution to that problem may ...

A laboratory error in 1956 by engineer Wilson Greatbatch led to a groundbreaking medical invention. While attempting to build ...

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 ...

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 ...

Pakistan, June 1 -- Chinese researchers have reached a significant milestone in cardiovascular science by creating the ...

Add Yahoo as a preferred source to see more of our stories on Google. Roughly one percent of infants are born with heart defects every year. The majority of these cases only require a temporary ...

In the normal heart, the heart's lower chambers (ventricles) pump in sync with the heart's upper chambers (atria). When a person has heart failure, often the right and left ventricles do not pump ...

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 ...

Scientists at Northwestern University unveiled the world's smallest pacemaker. The device is smaller than a grain of rice — and is suited particularly to help newborn babies with congenital heart ...
