Abstract

A leadless implantable medical device (LIMD) includes a housing formed from a battery and an end cap. A proximal end of the end cap forms an LIMD proximal end and a distal end of the battery case forms an LIMD distal end. A non-conductive coupler mechanically secures a terminal end of the battery case to a mating end of the end cap, while maintaining the battery case and end cap electrically separated. A first electrode projects from the proximal end of the end cap. An intra-cardiac (IC) device extension projects from the distal end of the battery case. The extension includes a second electrode that is electrically connected to the battery case. The second electrode is located remote from the LIMD distal end. An electronics module is located within an internal cavity of the end cap and communicates with the first and second electrodes.
