ABSTRACT:
A defibrillator having a housing for enclosing and containing defibrillation pulse generator circuitry, particularly adapted to allow for ease of manufacture and use. At least one surface of the housing is electrically conductive and may be connected to the defibrillation pulse generator circuitry for delivering defibrillating energy to the heart. The defibrillator is provided with two case-activating setscrew blocks isolated from two contacts. By tightening the first setscrew onto its contact, the can is activated and is positive for defibrillation. By tightening the second setscrew instead, the can is activated and is negative for defibrillation. Tightening neither setscrew maintains the inactive status of the can. By using this system, various electrode configurations can be used as required to provide the optimum system for a given patient. The defibrillator generator housing is preferably implanted in the left pectoral region proximate the heart with the conductive surface facing the heart. Other implantable electrodes are discharged against the defibrillator generator housing electrode.
