1. A delivery system for delivering a leadless pacemaker, comprising:
a first shaft having a shaft lumen extending along a longitudinal axis to a distal portion;
a docking cap disposed on the distal portion of the first shaft, wherein the docking cap includes a distal tip sloping inwards toward an interior wall defining an interior configured to receive a button, and wherein the interior wall is shaped to cup and contact the button when the leadless pacemaker is docked within the docking cap;
a sheath including a proximal end coupled to a catheter shaft and having a radiopaque feature, wherein the radiopaque feature is movable along the longitudinal axis relative to the first shaft to indicate whether the sheath is covering the leadless pacemaker;
a snare extending through the shaft lumen;
a deflection knob movable to steer the first shaft; and
a snare knob movable to move the snare relative to the docking cap.
