April 11, 2016 - The U.S. Food and Drug Administration (FDA) has approved the world's smallest pacemaker, the Medtronic Micra Transcatheter Pacing System (TPS). The device is the first FDA-approved product with miniaturized pacing technology that is cosmetically invisible and small enough to be delivered through a catheter. It is implanted directly into the heart, providing a safe alternative to conventional pacemakers without the complications associated with cardiac lead wires.
