Biostimulator transport system having torque limiter

A biostimulator transport system, comprising:

• an elongated flexible tubular member;
• a docking cap coupled to the elongated flexible tubular member, wherein the docking cap has a docking cavity to receive an attachment feature of a biostimulator
• a torque shaft extending from a proximal shaft end distally through the elongated flexible tubular member to a distal shaft end coupled to the docking cap;
• a handle having a handle cavity;
• and
• a torque limiter in the handle cavity, wherein the torque limiter includes a torque puck mounted on the proximal shaft end of the torque shaft, a torque shuttle coupled to the handle and the torque puck, and a slip mechanism between the torque shuttle and the torque puck to allow the torque shaft to rotate relative to the handle based on a resistance torque on the torque shaft.

A biostimulator retrieval system, comprising:

• an elongated flexible tubular member;
• a docking cap coupled to the elongated flexible tubular member, wherein the docking cap has a docking cavity to receive an attachment feature of a biostimulator;
• a torque shaft extending from a proximal shaft end distally through the elongated flexible tubular member to a distal shaft end coupled to the docking cap;
• a handle;
• a torque limiter including a torque puck mounted on the proximal shaft end of the torque shaft, a torque shuttle coupled to the handle, and a slip mechanism between the torque shuttle and the torque puck to allow the torque shaft to rotate relative to the handle based on a resistance torque at the docking cap;
• and
• a snare extending through the torque puck, the torque shaft, and the docking cap.
