Abstract

An end effector assembly for an electrosurgical device includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue therebetween. The jaw members cooperate to define a tissue grasping area. One or both of the jaw members includes an inner electrode. One or both of the jaw members includes first and second outer electrodes disposed on either side of the inner electrode. The inner and outer electrodes are configured to conduct energy through tissue grasped within the tissue grasping area to seal tissue. The inner and outer electrodes define different configurations such that, upon conduction of energy through tissue grasped within the tissue grasping area, tissue disposed adjacent the outer electrodes is boiled before boiling of tissue disposed adjacent the inner electrodes.
