An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed to capture tissue therebetween. One or both of the first and second jaws can comprise a plurality of electrodes which can be sequentially activated. The electrodes can be activated in a predetermined order in connection with a cutting member being advanced through the tissue. In various embodiments, the electrodes can be deactivated in a predetermined order. In certain embodiments, the electrodes can be comprised of a positive temperature coefficient material which can allow the electrodes to be sequentially deactivated.
