St. David’s doctor talks about new, smaller pacemaker

Micra TPS Pacemaker

AUSTIN (KXAN) — Doctors at St. David’s Medical Center are using a new heart device that is not only small, it’s groundbreaking.

Unlike traditional pacemakers, the Micra TPS—which is about the size of a large vitamin or capsule—does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy, making it virtually invisible.

Dr. Robert Canby with St. David’s Texas Cardiac Arrhythmia Institute says the device is small enough to be delivered through a catheter and implanted directly into the heart with small prongs. provides commenting to allow for constructive discussion on the stories we cover.
