1. A method of treating a patient comprising:
- providing an implantable cardiac stimulus system comprising operational circuitry for detecting and analyzing cardiac function and outputting cardiac stimulus, and a housing that contains the operational circuitry, attached to a lead;
implanting the cardiac stimulus system into a patient by establishing a subcutaneous space for receiving the cardiac stimulus system and inserting the cardiac stimulus system into the subcutaneous space without introducing a transvenous lead for association with the operational circuitry such that all components are disposed between the skin and the ribcage of the patient by placing the housing at the left posterior axillary line and the lead in the inframammary crease, ending in the anterior precordial region of the patient;
detecting and analyzing cardiac function to determine whether cardiac stimulus is indicated; and
if cardiac stimulus is indicated, delivering cardioversion/defibrillation energy using the operational circuitry.

Abstract
A power supply for an implantable cardioverter-defibrillator for subcutaneous positioning between the third rib and the twelfth rib and for providing cardioversion/defibrillation energy to the heart, the power supply comprising a capacitor subsystem for storing the cardioversion/defibrillation energy for delivery to the patient'"'"'s heart; and a battery subsystem electrically coupled to the capacitor subsystem for providing electrical energy to the capacitor subsystem.

11. A method of treating a patient comprising:
-
providing an implantable cardiac stimulus system having at least operational circuitry for detecting and analyzing cardiac function and outputting cardiac stimulus, a lead carrying a plurality of electrodes and means for housing the operational circuitry attached to the lead; implanting the cardiac stimulus system into a patient by establishing a subcutaneous space for receiving the cardiac stimulus system and inserting the cardiac stimulus system into the subcutaneous space without introducing a transvenous lead for association with the operational circuitry such that all components are placed between the skin and the ribcage of the patient by placing the housing at the left posterior axillary line and the lead in the inframammary crease, ending in the anterior precordial region of the patient; detecting and analyzing cardiac function to determine whether cardiac stimulus is indicated; and if cardiac stimulus is indicated, delivering cardioversion/defibrillation energy using the operational circuitry. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
