Method of producing an electrosurgical device
First Claim
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.

Abstract
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.

13. A method of producing an electrosurgical device, comprising:
-
forming a first elongate clamshell, wherein the first elongate clamshell includes a first face having a first plurality of spaced-apart grooves; forming a second elongate clamshell, wherein the second elongate clamshell includes a second face having a second plurality of spaced-apart grooves, wherein at least two of the second plurality of spaced-apart grooves in the second face oppose and correspond with at least two of the first plurality of spaced-apart grooves in the first face; disposing a first electrical conductor into one of the at least two of the first plurality of spaced apart-grooves; disposing a second electrical conductor into one of the at least two of the second plurality of spaced apart-grooves; aligning the first face against the second face to interlock the first face with the second face, wherein the aligning forms a first spaced-apart electrical passage and a second spaced-apart electrical passage each including one of the first electrical conductor and the second electrical conductor, wherein the first electrical passage is formed from aligning one of the at least two of the first plurality of spaced apart-grooves, and wherein the second electrical passage is formed from aligning one of the at least two of the second plurality of spaced apart-grooves, and wherein the aligning forms an elongate fluid passage from one of the at least two of the first plurality of spaced apart-grooves other than the corresponding one of the at least two of the first and second plurality of spaced apart-grooves; welding the first and second elongate clamshells together to integrally form a shaft member such that the first and second spaced-apart electrical passages and the fluid passage are each fluid-tight along a major longitudinal portion of the shaft member; and attaching a first electrode and a second electrode at a distal end of the shaft member, wherein the first electrode is in electrical communication with the first electrical conductor and the second electrode is in electrical communication with the second electrical conductor to form the electrosurgical device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

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