A method of producing an electrosurgical device is disclosed. Opposing longitudinal clamshells are formed, and each clamshell includes a face having a generally planar major portion. Longitudinal grooves are formed in a clamshell, and an electrical conductor in a disposed in a groove. The faces are aligned to form an electrical passage including the electrical conductor in the groove and a spaced-apart fluid passage with another groove. The clamshells are welded together to form a shaft member such that the electrical passage and the fluid passage are fluid tight along a major longitudinal portion of the shaft. Electrodes are attached to the distal end of the shaft and are in electrical communication with the electrical conductor.
