ELECTROSURGICAL DEVICES INCLUDING TRANSVERSE ELECTRODE CONFIGURATIONS
First Claim
1. An end effector assembly for an electrosurgical device, the end effector assembly comprising:
- first and second jaw members movable relative to one another between a spaced-apart position and an approximated position, each jaw member including an opposed tissue-contacting surface, the opposed tissue-contacting surfaces cooperating to define a tissue grasping area for grasping tissue therebetween when the jaw members are moved to the approximated position, one of the jaw members including;
an electrically-insulating body defining an outer back surface and an opposed surface that forms part of the tissue-contacting surface of the jaw member;
an interior electrode positioned interiorly of outer bounds of the tissue grasping area, at least a portion of the interior electrode forming part of the tissue-contacting surface of the jaw member; and
an exterior electrode positioned exteriorly of the outer bounds of the tissue grasping area, a first portion of the exterior electrode extending along the outer back surface of the body, a second portion of the exterior electrode disposed within the body, and a third portion of the exterior electrode positioned adjacent the outer bounds of the tissue grasping area, wherein the interior and exterior electrodes are configured to conduct energy therebetween and through tissue grasped within the tissue grasping area to seal tissue grasped within the tissue grasping area.

Abstract
An end effector assembly for an electrosurgical device includes first and second jaw members movable between spaced-apart and approximated positions. The jaw members include tissue-contacting surfaces that define a tissue grasping area. One of the jaw members includes an electrically-insulating body, an interior electrode, and an exterior electrode. The interior electrode is positioned interiorly of outer bounds of the tissue grasping area. A portion of the interior electrode forms part of the tissue-contacting surface. The exterior electrode is positioned exteriorly of the outer bounds of the tissue grasping area. At least one portion of the exterior electrode: extends along the outer back surface of the body, is disposed within the body, and is positioned adjacent the outer bounds of the tissue grasping area. The interior and exterior electrodes are configured to conduct energy through tissue grasped within the tissue grasping area to seal tissue.
