Abstract: A surgical system includes a generator that delivers a first RF power signal during a seal cycle, and a second RF power signal during a cut cycle. A surgical device is electrically coupled to the generator and has first and second jaws having respective opposing conductive seal surface electrodes configured for bi-polar sealing of spaced apart first and second portions of tissue compressed between the jaws during a seal cycle. The device further includes a cut electrode disposed within the first jaw, the cut electrode having an elongate conductive edge surface that presses against a third portion of the tissue located between the first and second portions when the jaws are compressing the tissue, wherein the cut electrode acts as a monopolar electrode that severs the third portion of the tissue during a cut cycle performed after the seal cycle.
