Abstract
A bipolar, fluid assisted coagulator/ablator probe having a coaxial bipolar electrode arrangement in which an elongated outer electrode is positioned concentrically around an elongated inner electrode. An elongated concentric electrical inner insulating layer is positioned between the outer electrode and the inner electrode. An outer insulating layer is concentrically disposed over the outer electrode such that only the annular distal end of the outer electrode is exposed for surgical activity. The inner electrode is hollow and forms a conduit for drawing fluid through the probe. The inner and outer insulating layers are a high-temperature cross-linked polyethylene. In addition, the elongated hollow electrode portion is curved near the distal end of the electrode portion, and the distal end has a beveled face that forms an acute angle with a common axis of the hollow elongated probe portion.
