Northwestern University researchers have engineered a temporary pacemaker so small that it can fit on the tip of a syringe and be injected, eliminating the need for surgery. The ...

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

Chicago — 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.

Roughly one percent of infants are born with heart defects every year. The majority of these cases only require a temporary implant for about seven days to allow time for the heart to naturally ...

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 ...

In a breakthrough development, scientists from Northwestern University, have unveiled the world's smallest pacemaker, tinier than one could ever imagine- even smaller than the size of a rice grain.

This picture obtained on April 2, 2025 shows a pacemaker next to a single grain of rice on a finger. The world's tiniest pacemaker, a temporary heartbeat regulator smaller than a grain of rice that ...

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 ...

Scientists said Wednesday they have developed the world's tiniest pacemaker, a temporary heartbeat regulator smaller than a grain of rice that can be injected and controlled by light before dissolving ...

When the temporary pacemaker is no longer needed, surgeons remove the pacemaker electrodes. But potential complications include infection, dislodgement, torn or damaged tissues, bleeding and blood ...
