A method of implanting a leadless intra-cardiac medical device. An introducer assembly is introduced into one of an inferior vena cava or a superior vena cava of a heart and maneuvered into a first chamber of the heart. A housing is pushed out of a sheath of the introducer toward a first implant location within the first chamber, and the housing is anchored to the first implant location. The sheath is moved away from the anchored housing, and an electrode is urged to a distal end of the sheath due to the pushing, anchoring, and moving. The sheath is maneuvered to a second chamber of the heart, and the electrode is forced into a second implant location with the second chamber. The electrode is anchored to the second implant location. The sheath is moved away from the electrode after the anchoring, and the sheath is removed from the heart.
