Abstract: The present disclosure provides a plasma catheter including a tubular member; a conductive cylindrical member; a first electrode; and a second electrode. The tubular member defines a longitudinal lumen therethrough and has a proximal portion and a distal portion. The conductive cylindrical member is disposed at the distal portion of the tubular member. The first electrode is embedded in a first side of the tubular member and coupled to the conductive cylindrical member. The second electrode is embedded in a second side of the tubular member diametrically opposed to the first side. The second electrode is offset from the tubular member and aligned with a center axis defined by the conductive cylindrical member.

Abstract: An electrosurgical forceps is provided. The electrosurgical forceps includes an end effector including first and second jaw members. One of the first and second jaw members is movable from an open configuration for positioning tissue between the first and second jaw members to a closed configuration for grasping tissue for subsequent electrosurgical treatment thereof. One or more cutting electrodes are positioned on the first and/or second jaw members. The cutting electrode(s) includes one or more piezo-elements that are configured to oscillate at a predetermined frequency when the cutting electrode(s) is energized to sever tissue.
