Claim 0:
1. An electrosurgical system comprising
an electrosurgical instrument comprising:
an elongate shaft having a proximal end, a distal end and a longitudinal axis extending from the proximal end to the distal end;
a first jaw connected to the elongate shaft, aligned with the longitudinal axis of the elongate shaft and being stationary relative to the elongate shaft, the first jaw being entirely conductive and having a cut channel extending lengthwise along and through the first jaw, and the first jaw comprising a monolithic seal surface comprising a plurality of seal paths surrounding the cut channel and spaced by a plurality of cavities between each of the plurality of seal paths, each of the plurality of seal paths having identical widths and differing lengths and each of the plurality of cavities having identical widths and differing lengths;
a second jaw pivotably coupled to the elongate shaft and pivotably movable relative to the first jaw, the second jaw comprising a first electrode, a second electrode and an insulator positioned between the first and second electrodes, the second electrode being shaped and sized like the first jaw and being on an upper portion of the second jaw and distal from the first jaw, and the first electrode being on a lower portion of the second jaw proximate to the first jaw and extending along an outer portion of a distal tip end of the second jaw, the first electrode being parallel with the second electrode; and
a cutting blade connected to a blade shaft disposed within the elongate shaft, the cutting blade arranged to fit within the cut channel of the first jaw; and

an electrosurgical generator arranged to supply radiofrequency (RF) energy to the electrosurgical instrument removably coupled to the electrosurgical generator, the generator being arranged to supply RF energy between the first electrode and the first jaw to coagulate tissue in contact with the first electrode and the first jaw and being arranged to supply RF energy between the first electrode, the second electrode and the first jaw to coagulate tissue in contact with the first electrode, the second electrode and the first jaw.
