The first pacemakers were developed in the 1960s and they have already come along way since then. Now we are entering a new phase of medicine with The Medtronic Micra Leadless Pacemaker. The culmination of technological advances in electronics miniaturisation and battery chemistry is this single chamber pacemaker that can be implanted entirely within the heart.
The Micra is a miniature single chamber leadless pacemaker system designed to pace only within the right ventricle of the heart. At 93% smaller than traditional pacemakers and with its increase battery life, the Micra device eliminates the need for a separate battery, a device pocket and insertion of a pacing lead minimising the risks these can pose.
Your doctor will insert a “tube-like” catheter into a vein in your upper thigh and use the catheter to position the Micra in the right ventricle of your heart. The catheter is then removed.
There are multiple potential benefits to the micra verses having a traditional pacemaker implant.

No, the Micra is for patients who need a single chamber pacemaker. Most patients who fall into this group are those who have permanent atrial fibrillation, in whom it is impossible to pace the atria when this rhythm is present.
