Abstract:
1. A leadless implantable medical device (LIMD) system comprising; a housing having a distal end and a proximal end, the distal end configured to be actively secured to tissue in an implant chamber of a heart; at least one electrode configured to perform at least one of sensing and pacing of at least one chamber of the heart; a processor to control sensing and pacing operations; an indwelling retrieval mechanism (IRM) having a distal end coupled to the proximal end of the housing, the IRM having a body configured to extend from the heart, along a vessel and exit the vessel at an exit/re-entry point; the IRM having a proximal end configured to be anchored at a temporary anchor site to at least one of subcutaneous tissue and muscle while the LIMD is implanted; the body of the IRM being formed of a flexible biocompatible and biostable material and having sufficient strength to maintain a desired level of structural integrity for a duration of time that the LIMD is implanted; a catheter having first and second lumen, the first lumen to receive the IRM; and an LIMD gripper device loaded into the second lumen and advanced until projecting from an open end of the catheter, a distal end of the LIMD gripper device coupling to a proximal end of the LIMD.
