Claim Text:
1. A method of producing an electrosurgical device, comprising: forming a first elongate clamshell and a second elongate clamshell from an electrically insulating material, wherein the first elongate clamshell includes a first face having a plurality of spaced-apart grooves and the second elongate clamshell includes a second face having a second groove opposing one of the plurality of spaced-apart grooves in the first face; disposing an electrical conductor into one of the plurality of spaced-apart grooves and the second groove; aligning the first face against the second face to interlock the first face with the second face and to form an electrical passage including the electrical conductor and a spaced-apart fluid passage from another groove of the plurality of spaced-apart grooves in the first elongate clamshell; welding the first elongate clamshell and the second elongate clamshell together to integrally form a shaft member such that the electrical passage and the fluid passage are each fluid-tight along a major longitudinal portion of the shaft member; and attaching an electrode at a distal end of the shaft member to be in electrical communication with the electrical conductor and to form the electrosurgical device.
