What is a leadless pacemaker?

A leadless pacemaker is a pacemaker that has no wires. It is implanted directly into the heart but does not require a surgical procedure. The leadless pacemaker is threaded through a vein in the groin region using a catheter and inserted into the bottom chamber of the heart, called the ventricle. The ventricle is the main pumping chamber of the heart.

The leadless pacemaker is about 90 percent smaller than a traditional pacemaker. It is about the size of a large vitamin and the weight of a penny. Despite its small size all of the electronics and the battery are within that capsule, and it is able to perform all the traditional functions of a pacemaker. Its battery is estimated to last ten to twelve years depending on how much the person uses it. The leadless pacemaker is a revolutionized concept in medical or cardiac devices.
