Northwestern University engineers have created an ultra-tiny pacemaker that can be injected through a syringe and naturally dissolves once it is no longer needed. Designed for temporary use, particularly in newborns with congenital heart defects, the device eliminates the need for surgical removal.<\/p>\n\n\n\n
Smaller than a grain of rice, the pacemaker pairs with a wireless, wearable device on the chest that detects irregular heartbeats and activates the pacemaker using infrared light pulses. These pulses penetrate the skin and tissues to regulate heart rhythm.<\/p>\n\n\n\n
Instead of traditional bulky batteries, the device generates power using a chemical reaction between metal electrodes and body fluids. The innovation eliminates the risks associated with wired pacemakers, such as infections or tissue damage during removal.<\/p>\n\n\n\n
Published in Nature, the study demonstrated the pacemaker\u2019s effectiveness in animal models and human donor hearts. Researchers believe this breakthrough could significantly improve temporary heart pacing, especially for pediatric patients.<\/p>\n","protected":false},"excerpt":{"rendered":"
