Abstract
A bipolar electrosurgical fusion/sealer and dissector is provided that is arranged to simultaneously fuse and cut tissue captured between jaws of the instrument. The jaws include particularly positioned, shaped and/or oriented electrodes along with a compressible landing pad to perform the simultaneous fusion and cutting of tissue. An electrosurgical generator is arranged to supply RF energy through the instrument and monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle to optimally fuse and dissect the tissue.
