Scientists have developed an ultra-small, fully dissolvable pacemaker designed to temporarily support the heart during recovery. Unlike traditional pacemakers that require surgical removal, this device naturally breaks down inside the body after completing its job—representing a major leap toward safer, less invasive cardiac care. • The device is roughly the size of a grain of rice and made from bioresorbable materials • Designed to provide temporary electrical stimulation during early healing •
