Abstract
A bipolar forceps for sealing tissue includes an end effector assembly having opposing first and second jaw members each having a proximal end and a distal end. A first electrically conductive surface having two or more conductive sealing plates and a dielectric layer is operably coupled to the first jaw member. Each sealing plate is connected to a reactive element and positioned along the first electrically conductive surface from the proximal end to the distal end. The reactive element of the sealing plate have different impedances. A second electrically conductive surface having one or more conductive sealing plates is operably coupled to the second jaw member. Each electrically conductive surface on the jaw members connects to a source of electrosurgical energy such that the sealing plates are capable of conducting energy through tissue held therebetween to effect a tissue seal.
