Patent ID: 8685018

Claim:
An electrosurgical wand comprising: an elongate housing that defines a handle end and a distal end; a connector comprising a first and second electrical pins; a first discharge aperture on the distal end of the elongate housing, the first discharge aperture fluidly coupled to a first fluid conduit, and the first fluid conduit within the elongate housing; a first active electrode of conductive material disposed on the distal end of the elongate housing, and the first active electrode electrically coupled to the first electrical pin; a first return electrode of conductive material completely disposed within the first fluid conduit and recessed proximally from the first discharge aperture, the first return electrode within at least a portion of a fluid path directed through and to contact the first return electrode before discharging through the first discharge aperture toward the first active electrode, and the first return electrode electrically coupled to the second electrical pin; and an aspiration aperture on the distal end of the elongate housing fluidly coupled to a second fluid conduit, the second fluid conduit within the elongate housing.
