World’s Smallest Pacemaker Implanted

Tuesday, 10 December 2013 | by Pat's Picks

A pacemaker the size of a vitamin has been successfully implanted directly into a human heart. The Minneapolis Star-Tribune says the device by Medtronic is just 1/10th the size of a traditional pacemaker. The device is delivered to the heart using a catheter and does not require wires known as leads to connect to the heart.
