Mark W Kroll, Theodore P Adams, Charles G Supino: Optimal energy steering for an implantable defibrillator. Angeion Corporation, Patterson and Keough, April 26, 1994: US05306291 (80 worldwide citation)

Epicardial-patch electrodes for defibrillation are efficient in deliverying electrical energy accurately to the necessary tissue and in minimizing electrical losses, but they are risky and costly because their implantation requires major surgery. Intravenous implantation of endocardial-coil electrod ...

Mark W Kroll, Theodore P Adams, Charles G Supino: Implantable defibrillator for producing a rectangular-shaped defibrillation waveform. Angeion Corporation, Patterson & Keough, May 7, 1996: US05514160 (27 worldwide citation)

An implantable defibrillator derives a rectangular current waveform from a capacitor discharge by using a current limiter. This pulse-shaping method is equally applicable to single-path and multiple-path situations. A rectangular pulse delivers a maximum of energy for a given peak-field value with a ...

The first embodiment of the present invention repositions the shunt thyristor used in the monophasic-waveform generator of the prior art so that it discharges the main capacitor through a series thyristor, thus increasing current through it briefly, rather than reducing current through it. The resul ...
