Claim 5:
6. A cardiac stimulation device, comprising:
a cylindrical body comprising a flexible distal portion and a distal end;
a fixation member extending distally from the distal end of the cylindrical body and being configured to pierce into a septal wall of a patient's heart and to secure the device to the septal wall;
a first cathode electrode formed on the fixation member;
a second cathode electrode formed on the distal end of the cylindrical body, wherein an entirety of the second cathode electrode extends within an inner perimeter of the fixation member, and wherein the second cathode electrode forms a non-piercing active face configured to maintain active external contact with a corresponding outer surface area of the septal wall within the inner perimeter of the fixation member when the fixation member secures the device to the septal wall; and
a pulse generator coupled to the first and second cathode electrodes and configured to deliver negatively charged cardiac pacing pulses to the first and second cathode electrodes.
