Abstract
An electrosurgical apparatus for cutting and/or coagulating living tissue, a method of forming the electrosurgical apparatus, and a method of using the electrosurgical apparatus. The cutting and/or coagulating living tissue is performed with one or two heated loops of resistance wire accompanied by sufficient electrical current across the living tissue to enable said cutting and/or coagulating to be performed. The electrosurgical apparatus may include: a glow blade having one or two glow loops of resistance wire; a radio frequency (RF) generator; and one or two voltage supplies configured to operate concurrently, while the one or two glow loops are heated to said glow, to supply both sufficient RF power and associated electrical current across the living tissue for cutting and/or coagulating the living tissue by the one or two glow loops. A first output of the RF generator is electrically coupled to the one or two glow loops.
