Abstract
An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes an electrically conductive tissue contacting surface connected to an electrosurgical energy source. At least one of the jaw members includes an electrically conductive cutting element disposed within an insulator defined in the jaw member. A rigid structural support is included which is configured to support the electrically conductive tissue sealing surface and includes at least one flow channel defined therein.
