World’s Smallest Pacemaker

Heart Hospital of Lafayette continues to lead the way in cardiac care as the first hospital in Acadiana to offer patients the world’s smallest pacemaker, the Micra® Transcatheter Pacing System (TPS). The Micra® TPS is designed for patients with bradycardia, a condition characterized by a slow or irregular heart rhythm that causes dizziness, fatigue and fainting spells. Pacemakers are the most common way to treat bradycardia to help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.

This new Micra TPS provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker—comparable to a large vitamin. Dr. Patrick Welch at Heart Hospital is an advocate of the Medtronic Micra TPS because, unlike traditional pacemakers, the device does not require cardiac wires (leads) or a surgical “pocket” under the skin to provide a pacing therapy. Instead, the device is small enough to be delivered through a catheter and implanted directly into the heart with small tines, providing a safe alternative to conventional pacemakers without the complications associated with leads. In addition, both physicians and their patients love the fact that use of the Micra TPS eliminates a chest scar or bump meaning it is cosmetically invisible.

Micra Pacemaker Benefits

Comparable in size to a large vitamin, the Micra TPS provides the most advanced pacing technology—all while being cosmetically invisible.

Unlike traditional pacemakers, the device does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy.

The Micra TPS is small enough to be delivered through a catheter and implanted directly into the heart with small tines.

Patients will not have a chest scar or a bump, nor the discomfort or visible, reminder of a pacemaker under the skin.

Customized to each patient’s needs, the Micra TPS automatically adjusts pacing therapy based on a person’s activity levels.

The Micra TPS is the first and only transcatheter pacing system approved for both 1.5 and 3 Tesla (T) full-body magnetic resonance imaging (MRI) scans and is designed to allow patients to be followed by their physicians and send data remotely via the Medtronic CareLink® Network.
