Abstract
An electrode sealing assembly for use in combination with an electrosurgical instrument includes first and second jaw members which are movable from a first, spaced-apart position to a second position to grasp tissue. Each of the jaw members includes an insulative housing, a thermally conductive, electrically non-conductive material and a sealing plate. The insulative housing has a series of electromechanical interfaces which mate with a corresponding series of electromechanical interfaces which extend from the sealing plate such that the sealing plates are a capable of conducting bipolar energy through tissue held between the jaw members. The thermally conductive, electrically non-conductive material is configured to encapsulate and secure the sealing plate to the insulative housing.
