Abstract

A retrieval system for a biostimulator, such as a leadless cardiac pacemaker, is described. The biostimulator retrieval system includes a docking cap rotatably coupled to an outer catheter by a bearing. A torque shaft extends through the outer catheter and attaches to the docking cap to transmit torque to the docking cap to cause rotation of the docking cap relative to the outer catheter. The rotating docking cap can transmit torque to an attachment feature of a biostimulator received within the docking cap. The attachment feature can be captured by a snare that extends through the torque shaft. A cincher tube extends through the torque shaft around the snare, and advances over the snare independently from the torque shaft that is attached to the docking cap, to cinch the snare onto the attachment feature. Other embodiments are also described and claimed.
