Abstract: A partially coated electrosurgical electrode has a portion of a medical grade metallic material as a substrate for energy application. Conductive sites of metallic material or alloys thereof pass energy through peaks that define valleys nearby. A partial coating in the valleys has a low surface free energy. A treated surface across the peaks and generally over the filled valleys is relatively smooth for non stick characteristics during application of electrosurgery to tissue and bodily fluids. Openings in the treated surface through the partial coating are at the peaks of conductive sites to expose the metallic material or alloys thereof. The partial coating is a fluorinated polymer. The treated surface is a relatively even level that is not flat. The metallic material substrate is an alloy of stainless steel or nickel chrome. A mechanically deformed surface finish, plasma or vapor deposition on the substrate forms the conductive sites. A method of manufacturing the electrode has steps including preparing the metallic conductor, making it with the conductive material having peaks above the valleys as conductive sites, applying the partial coating to it and treating the surface across the peaks and generally over the filled valleys of the partially coated electrically conductive electrode. Locating the openings among the valleys is a step. Treating may be mass finishing, such as vibratory or tumbling the partially coated electrodes with or without abrasive material media or polishing, buffing, surface grinding, abrasive belt grinding or sanding with abrasive material. Making the peaks and valleys can be by stamping, coining, burnishing, embossing, threading, tumbling, vibrating, shot peening, wire brushing, grit blasting, thermal spraying, with powder, with wire supplied to melt and be distributed, or with high velocity oxygen fuel and a nickel, cobalt alloy, stainless steel or a nickel chrome alloy. A manufacturing method for the electrode has coating a strip of metal with the low surface energy polymer and forming it in a stamping operation with a raw metal edge.
