Abstract
A bipolar electrosurgical forceps for treating tissue includes a pair of opposing first and second jaw members each having a tissue engaging surface disposed thereon. Each of the jaw members is movable relative to one another from a first position to approximate tissue to a second position for engaging tissue therebetween. The first jaw member includes a plurality of ring electrodes disposed thereon having a first electrical potential and the second jaw member includes a corresponding plurality of post electrodes disposed thereon having a second electrical potential. Each of the plurality of post electrodes is inwardly disposed of a respective ring electrode to form an electrode micro-sealing pad wherein upon activation of the forceps tissue grasped between each electrode micro-sealing pad is sealed while tissue adjacent to each electrode micro-sealing pads remains viable.
