What is the primary characteristic of the Micra catheter pacing system?

The Micra catheter pacing system is a significant advancement in cardiac pacing technology characterized primarily by its delivery method. The correct answer highlights that the Micra device is delivered percutaneously into the right ventricle. This minimally invasive approach allows the pacemaker to be implanted via a small incision rather than requiring open-heart surgery or even a traditional pocket in the chest for a conventional pacemaker, which can lead to reduced recovery time and lower infection risk.

The nature of its delivery is crucial because it contributes to the overall design and function of the Micra system, allowing it to provide effective pacing while minimizing procedural risks and complexities associated with lead management. The Micra system is designed to be a leadless pacing option, which also eliminates many of the complications associated with traditional leads.

Other choices do not reflect the innovative features of the Micra system. For instance, the Micra does not use multiple leads but rather operates with a single leadless design. Additionally, it is self-contained, requiring no external power source, and is designed for permanent pacing rather than just temporary applications. This innovative approach significantly changes how patients with pacing requirements are treated, emphasizing the advantages of a more streamlined and patient-friendly procedure.
