The jaw members (11, 12) define opposed tissue-contacting surfaces (13, 14) that cooperate to define a tissue grasping area within which tissue is grasped when the jaw members (11, 12) are moved to the approximated position. At least one of the jaw members (11, 12) includes an interior electrode (79) and at least one of the jaw members includes first and second exterior electrodes (78a, 78b). The interior and exterior electrodes (79, 78a, 78b) are configured to conduct energy through tissue grasped within the tissue grasping area to seal tissue. The interior electrodes (79) are disposed interiorly of outer bounds of the tissue grasping area, while the exterior electrodes (78a, 78b) are disposed exteriorly. As a result, upon conduction of energy through tissue grasped within the tissue grasping area, tissue disposed adjacent the exterior electrodes (78a, 78b) is boiled before boiling of tissue disposed adjacent the interior electrodes (79).
