Abstract
An electrosurgical apparatus includes a rotary, tissue affecting device in the form of one or more rotating blades, a rotating drill, or a rotating shaving/abrading device that serves as an active, energy delivering electrode. The active electrode effectively cuts tissue at the surgical site without relying solely upon the mechanical cutting action of the tissue affecting device. The rotary surgical device can be in a form such that it is suitable for use in open or closed surgery.
