1. An implantable leadless cardiac pacing device comprising:
- a housing having a proximal end and a distal end;
an electrode positioned proximate the distal end of the housing configured to be positioned adjacent cardiac tissue; and
a docking member extending from the proximal end of the housing along a central longitudinal axis of the housing, the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device;
the docking member including a head portion centered on the central longitudinal axis and a neck portion centered on the central longitudinal axis, the neck portion extending between the housing and the head portion;
the head portion having a radial dimension measured from the central longitudinal axis to an outer peripheral surface of the head portion and the neck portion having a radial dimension measured from the central longitudinal axis to an outer peripheral surface of the neck portion,wherein the radial dimension of the neck portion is less than the radial dimension of the head portion;
the head portion including a recess extending into the head portion from a proximal surface of the head portion to a proximally-facing surface formed within the head portion;
wherein the recess opens out to the peripheral surface of the head portion and the proximal surface of the head portion.

11. An implantable leadless cardiac pacing device comprising:
-
a housing having a proximal end and a distal end; an electrode positioned proximate the distal end of the housing configured to be positioned adjacent cardiac tissue; and a docking member extending from the proximal end of the housing along a longitudinal axis of the housing, the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device; the docking member including a head portion and a reduced diameter neck portion extending between the housing and the head portion; the head portion having a proximal surface and an outer circumferential surface; the head portion including a recess extending laterally across the head portion from a first location on the outer circumferential surface on a first side of the head portion to a second location on the outer circumferential surface on a second side of the head portion opposite the first side of the head portion relative to the longitudinal axis; wherein the recess is at least partially defined by a proximally-facing surface formed within the head portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
