Detailed explanation-1: -The world’s smallest pacemaker has been fitted inside the heart of a UK patient, medics have said. The Micra Transcatheter Pacing System was fitted for the first time in England at Southampton General Hospital. Consultant cardiologist Prof John Morgan said the procedure was a “landmark moment".
Detailed explanation-2: -Micra is single-chamber pacemaker that is about the size of a vitamin and can be implanted directly into the heart, eliminating the need for the leads to also be implanted. The minimally invasive procedure allows electrophysiologists to implant the pacemaker through a catheter in the leg so no chest incision is needed.
Detailed explanation-3: -When Medtronic unveiled the Micra™ Transcatheter Pacing System (TPS) to the world in 2013, some cardiac electrophysiologists were skeptical.
Detailed explanation-4: -Micra™ is the world’s smallest pacemaker. Unlike most pacemakers that are placed in a patient’s chest with leads running to the heart, Micra is a leadless pacemaker because it’s implanted directly into the heart. Less invasive-Micra is placed in the heart via a vein in the leg.
Detailed explanation-5: -The Micra device is manufactured by Medtronic, located in Mounds View, Minnesota.
