Micra is a novel leadless pacemaker that helps maintain a regular heart rate. It is smaller than traditional pacemakers due to not requiring leads. Micra has four main components - tines to anchor it in the heart, a processing unit, battery, and titanium case. It is implanted using a catheter and has advantages over traditional pacemakers like being less invasive, more durable, and not being affected by electromagnetic fields. However, it also has disadvantages like higher cost and rare risk of abnormal bleeding. Future improvements could include self-powered nano generators and dual-chamber pacing capabilities.
