  • IMPLANT DELIVERY AND RETRIEVAL SYSTEMS AND METHODS
    Publication number: 20260114900
    Abstract: Systems and methods for delivering and retrieving a leadless pacemaker are described. A leadless pacemaker retrieval system includes a catheter system having a snare assembly to capture the leadless pacemaker. The catheter system includes sheaths extending distally from a shaft, and the snare assembly includes several snare legs, such as segments of snare loops, that extend from one sheath to connect to another sheath. The snare loops can have bights that connect to opposing sheaths to form a docking space between the legs of the snare loops and radially between the sheaths. The snare assembly is movable between an engaged position and a disengaged position by translating the snare legs within lumens of the corresponding sheaths. In the engaged position, the snare assembly tightens around the leadless pacemaker to allow the leadless pacemaker to be retrieved. Other embodiments are also described and claimed.
