Micratm the leadless pacemaker

So your heart doesn't miss a beat

Micra™ is the world’s smallest pacemaker1 and is 93% smaller than traditional pacemakers2 (about the size of a large vitamin capsule).

It is a leadless pacemaker, and completely self-contained within the heart, providing the therapy you need without the visible reminder of a traditional pacemaker.

The Micra™ design and implanting procedure can mean fewer complications, fewer post-implant activity restrictions, and reduced obstruction to shoulder movement.3

93% smaller


Unlike a standard pacemaker, Micra™ is implanted into the heart through a vein in your groin and does not require a lead

Micra™’s miniaturised size and minimally invasive approach leaves no visible sign of a medical device under the skin.
