1. A leadless pacemaker system, comprising:
a leadless pacemaker having a docking projection including a docking surface opening; and
a catheter-based system including
a catheter shaft extending along a central axis, and
a set of arms having respective tabs extending radially outward from the catheter shaft, wherein the set of arms are integral with the catheter shaft such that the catheter shaft extends directly radially in between the respective tabs of the set of arms, wherein the set of arms include a first arm disposed opposite a second arm around the central axis, and wherein the set of arms include a disengaged state in which the set of arms are biased radially inward such that the respective tabs of the set of arms can advance through the docking surface opening and an engaged state in which the respective tabs of the set of arms are biased radially outward to lock the set of arms to the docking projection.
