Abstract

An electrode assembly for an electrosurgical ablator may include an insulator having a distal end portion and a proximal end portion. The insulator may include a rim forming a distal extent of the distal end portion and an aperture disposed in the distal end portion. An electrode is disposed in the aperture and forms a cavity having a profile shape recessed from the distal end portion toward the proximal end portion. The electrode assembly projects a focal point of an ablation region emitted from the supply electrode through the projecting rim to a projection distance beyond the distal extent.
