A retrieval device and an associated implantable cardiac pacing device. The retrieval device includes a grasping mechanism configured to capture a docking member of the implantable cardiac pacing device to draw the implantable cardiac pacing device into the lumen of a retrieval catheter. The grasping mechanism is expandable from a first position to a second position and is biased toward the first position in an equilibrium condition. The grasping mechanism is configured to surround and pass over a head portion of the docking member in the second position, and be contracted toward the first position to capture the docking member with the grasping mechanism.
