Abstract

An apparatus includes a shaft assembly and an electrode assembly at a distal end of the shaft assembly. The electrode assembly includes a first conductive segment extending along a first angular range at the distal end of the shaft assembly. The first conductive segment is operable to apply RF energy to tissue at a first polarity. The electrode assembly further includes a second conductive segment angularly spaced apart from the first conductive segment. The second conductive segment extends along a second angular range at the distal end of the shaft assembly. The second conductive segment is operable to apply RF energy to tissue at a second polarity such that the first and second conductive segments are operable to apply bipolar RF energy to tissue.
