1. A method of inserting an implantable cardioverter-defibrillator within a patient, the method comprising the steps of:
- providing a cardioverter-defibrillator comprising a housing, an electrical circuit located within the housing, a first subcutaneous electrode located on the housing, and a second subcutaneous electrode spaced from the housing;
making a single incision into the patient;
advancing the housing through the single incision and subcutaneously over approximately the anterior portion of a patient'"'"'s ribcage;
advancing the second subcutaneous electrode through the single incision and subcutaneously over the patient'"'"'s ribcage; and
orienting the second electrode such that it is substantially positioned in the range of approximately 30 degrees to approximately 180 degrees with respect to the patient'"'"'s heart, from the first electrode.

23. An implantable cardioverter defibrillator for subcutaneous positioning between the third rib and the twelfth rib within a patient, the implantable cardioverter-defibrillator comprising:
-
a housing; an electrical circuit located within the housing; a first electrode coupled to the electrical circuit; and a second electrode coupled to the electrical circuit, wherein the second electrode is positioned approximately 30 degrees to approximately 180 degrees, with respect to the patient'"'"'s heart, apart from the first electrode; wherein the first electrode is contained within a single face of the housing, the face of the housing being concave;
wherein the first electrode emits and focuses an effective field strength through the patient'"'"'s heart to shock the heart. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
