Abstract
A defibrillator pulse generator device for implantation in the pectoral position of a patient. The pulse generator device has a compact, light weight housing structure. A power source, a capacitive member and a sensing and control structure are enclosed in the housing structure. A connecting structure mounted on the housing provides connection to the electrode leads of the defibrillator system.
