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.
