A new, tiny pacemaker — smaller than a grain of rice — developed at Northwestern University could play a sizable role in the future of medicine, according to the engineers who developed it.

A pacemaker is an electric medical device that’s generally about the size of a matchbox. A surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias. Pacemakers can ...

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 ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...

This story is part of a series on the current progression in Regenerative Medicine. This piece discusses the regeneration of the cardiovascular system. In 1999, I defined regenerative medicine as the ...

You may have heard of two little devices that doctors use to help treat heart problems: pacemakers and ICDs (implantable cardioverter defibrillators). They use them when you have a type of heart ...

A pacemaker is a small electronic device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias. It is generally not too ...

Pengju Li consults to the Pritzker School of Molecular Engineering. He receives funding from the University of Chicago. By harnessing light, my colleagues and I designed a wireless, ultrathin ...

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 ...
