A Tiny Breakthrough in Cardiac Care
Researchers at Northwestern University have unveiled a groundbreaking pacemaker that is smaller than a grain of rice. Measuring just 1.8 mm wide, 3.5 mm long, and 1 mm thick, this device provides electrical stimulation similar to conventional pacemakers while being significantly less invasive.
Wireless, Battery-Free, and Biodegradable
Unlike traditional pacemakers, this revolutionary device is wireless and battery-free, drawing energy from external sources. A major advantage is its bioresorbable nature, meaning it dissolves in the body after completing its function. This eliminates the need for surgical removal, reducing risks such as infections and tissue damage.
A Lifesaver for Newborns and Adults
This miniaturized pacemaker is especially beneficial for newborns with congenital heart conditions. In cases where temporary heart rhythm regulation is needed, such as during surgery or post-heart attack recovery, this device offers a safer, more efficient solution.
A Step Forward in Medical Innovation
This development builds on Northwestern’s 2021 transient pacemaker, further refining the technology to make it even smaller and more effective. By introducing a device that is both biodegradable and minimally invasive, scientists have taken a significant step in revolutionizing cardiac care.
