摘要：
A method of sealing tissue includes providing an end effector assembly including first and second jaw members. One or both of the jaw members includes an interior electrode and one or both of the jaw members includes first and second exterior electrodes disposed on either side of the interior electrode. The method further includes grasping tissue between the first and second jaw members and conducting energy between the interior and exterior electrodes to seal tissue grasped between the first and second jaw members. During tissue sealing, tissue disposed adjacent the exterior electrodes boils faster than tissue disposed adjacent the interior electrodes.
