Abstract
A method for conducting electrosurgery using increased crest factors employs an electrosurgical instrument having at least one conductive element that is surrounded by an insulation layer except at a conductor edge portion of the conductive element. The conductor edge portion and insulation layer each having unique geometric shapes and composition of the parts concentrate the electrosurgical power, reduce or eliminate the production of smoke and eschar and reduce tissue damage. The outer profile of the insulation layer and conductive element are configured to facilitate the flow of electrosurgical decomposition products away from the conductor edge where they are formed. The combined effects of the electrosurgical instrument configurations enable safe use of crest factors of 5 or greater in electrosurgical procedures.
