Patent Images
1. A method of inserting an implantable cardioverter-defibrillator within a patient, the method comprising the steps of:
- providing a cardioverter-defibrillator comprising a unitary housing, an electrical circuit located within the housing, and an electrode located on the housing, wherein the unitary housing has an exterior surface that is tapered from a first width at a proximal end to a second, smaller width at a distal end, wherein the cardioverter-defibrillator is configured to maintain the electrode in a predetermined relationship subcutaneously over a patient'"'"'s ribcage;
making an incision on a patient'"'"'s thorax; and
advancing the cardioverter-defibrillator through the incision and subcutaneously over a patient'"'"'s ribcage, wherein the cardioverter-defibrillator is advanced approximately between a patient'"'"'s third and a patient'"'"'s twelfth rib.
