Abstract
An implantable cardioverter defibrillator (ICD) in which capacitor systems are automatically reformed using a software-implemented computer system. The charge history and performance of the capacitor system are measured to perform intelligent calculations and to set the automatic capacitor reforming cycle. Individual capacitors among a group of many are isolatively charged as needed. Moreover, a sub optimal charge is used to automatically reform the capacitors to efficiently use battery energy. Further, excess charge is directed from one capacitor to another to thereby conserve energy. Specifically, the disclosure relates to an autonomous capacitor charging system which enhances ICD reliability to sustain real time provision of high current pulses.
