Claim 0:
1. A leadless pacemaker, comprising:
a cell having a negative terminal and a positive terminal;
a cell housing within which the cell is disposed, the cell housing directly electrically-coupled to the negative terminal of the cell,
a tip electrode;
an insulator that electrically isolates the tip electrode from the cell housing; and
pacing electronics configured to cause the cell housing, which is directly electrically coupled to the negative terminal of the cell, to serve as a positive ring or can electrode when providing a stimulation pulse from the cell housing to the tip electrode through cardiac tissue by selectively discharging a charge stored on a capacitor into the cell housing when providing the stimulation pulse from the cell housing to the tip electrode through cardiac tissue.
