摘要：
An end effector assembly for an electrosurgical device includes first andsecond jaw members movable between spaced-apart and approximated positions.The jaw members define opposed tissue-contacting surfaces that cooperate todefine a tissue grasping area within which tissue is grasped when the jawmembersare moved to the approximated position. At least one of the jaw membersincludesan interior electrode and at least one of the jaw members includes first andsecondexterior electrodes. The interior and exterior electrodes are configured toconductenergy through tissue grasped within the tissue grasping area to seal tissue.Theinterior electrodes are disposed interiorly of outer bounds of the tissuegrasping area,while the exterior electrodes are disposed exteriorly. As a result, uponconduction ofenergy through tissue grasped within the tissue grasping area, tissue disposedadjacent the exterior electrodes is boiled before boiling of tissue disposedadjacentthe interior electrodes.
