Micra® Transcatheter Pacing System

Micra Transcatheter Pacing System

Unlike traditional pacemakers, the Micra® Transcatheter Pacing System (TPS) is a miniaturized, fully self-contained pacemaker that delivers the most advanced pacing technology available to patients via a minimally-invasive approach. It weighs only 2 grams—comparable in size to a large vitamin pill—and is less than one-tenth the size of traditional pacemakers (~1cc). It is attached to the heart via small tines and does not require cardiac wires (leads) or a surgical “pocket” under the skin, avoiding the risk of pocket or lead infection, as well as potential long-term risks associated with lead fracture. It has an estimated average 10-12-year battery life and is fully MRI safe.

Deborah Cardiac Electrophysiologist Pedram Kazemian, MD, led the team which implanted the first TPS in 80-year-old Ronald Palmer of Barnegat. Mr. Palmer, who has had bradycardia and permanent atrial fibrillation, received the new small, sleek pacemaker, offering him an alternative to a traditional pacemaker, which he had previously and that had been extracted due to infection of the pacemaker pocket. The new device was implanted through a groin catheter during a relatively short procedure. Once implanted, nothing was visible from the outside of Mr. Palmer’s chest.

Any patient requiring a single-lead pacemaker is eligible for the new device, and it is of particular benefit to older patients who have had a prior infection or difficulty with vascular access. For more information about the device, contact Deborah’s EPS team at 609-893-1200 ext. 5100.
