Frederick W Rexroth: Electrosurgical generator. Medical Research Associates 2, Epstein & Edell, November 5, 1985: US04550727 (4 worldwide citation)

An electrosurgical generator, having particular utility in surgical procedures on human joints, is provided with an output impedance in the range of 600 to 2,500 Ohms in order to efficiently transfer energy to the high impedance joint. The relatively high output impedance permits much lower power se ...
