The Medtronic Micra Transcatheter Pacing System (TPS) is a leadless pacing system
implanted directly into the heart (Medtronic Micra® TPS Clinician Manual). Leadless pacing
systems have advantages over traditional transvenous pacing systems including the ability to leave the device implanted (indefinitely) once it has reached end of service due to battery depletion. Specifically, Micra TPS can remain safely implanted in the heart, even after patient death.
However, because the Micra TPS is delivered intravenously and implantation is directly into the patient’s heart, physical evidence of a pacemaker may no longer be apparent to medical examiners or mortuary staff during examination of a deceased patient.
