US EditionWorld's tiniest pacemaker is smaller than grain of rice
- Northwestern University engineers developed and unveiled the world's smallest pacemaker, smaller than a grain of rice, in a study published on Wednesday in Nature.
- The device addresses risks of traditional temporary pacemakers, which require wires sewn onto the heart and removal that can cause rare but lethal complications.
- The pacemaker is inserted via catheter or syringe, placed in or on the heart, and activated wirelessly by a patch worn on the chest that emits light pulses to control rhythm.
- About 40,000 U.S. Babies are born yearly with heart defects, many needing temporary pacing post-surgery, and the device designed to dissolve after use may help infants and adults, according to researchers.
- Researchers plan to seek FDA approval and start human trials, believing the technology could transform short-term cardiac pacing if clinical results confirm its safety and effectiveness.

Smaller Than a Grain of Rice: Engineers Develop World’s Smallest Pacemaker
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 be injected into the body using a syringe. While it is compatible with hearts of various sizes, the pacemaker is especially [...]
World’s smallest pacemaker uses light to activate
Northwestern University engineers have developed the world’s smallest pacemaker, which is light-activated and can be injected non-invasively, offering a new potential treatment for newborns with congenital heart defects. CNN Health’s Jacqueline Howard speaks to a biomedical engineer about the sesame-sized pacemaker.
"A very exciting perspective": smaller than a grain of rice, a temporary pacemaker to regulate the heart rate of newborns
In the clinical trial phase, this device aims to maintain a normal heart rate for the time necessary to restore the infant's heart, following a cardiac intervention. However, a Belgian specialist emits a few flats. ...

Engineers develop tiny pacemaker, smaller than a grain of rice
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. Researchers unveiled the device, which they say is the smallest pacemaker in the world, in a study published Wednesday in the peer-reviewed journal Nature. Though the device is still years away from being used in humans, it could eventually be useful for infa…
