Abstract:
1. A leadless implantable medical device (LIMD) configured to be implanted within a local chamber of the heart, said LIMD comprising: a housing formed from a battery and an end cap, the battery having a battery case with a distal end and a terminal end, the end cap having a mating end and a proximal end, the proximal end of the end cap forming an LIMD proximal end and the distal end of the battery case forming an LIMD distal end; a non-conductive coupler mechanically securing the terminal end of the battery case to the mating end of the end cap, while maintaining the battery case and end cap electrically separated from one another; a first electrode joined to the proximal end of the end cap, projecting from the LIMD proximal end and configured to engage tissue at a first activation site; and a second electrode that is electrically connected to the battery case, the battery case forming part of a circuit that connects the second electrode to sense or stimulate tissue at a second activation site.
