Abstract
A method of sealing bowel tissue includes grasping bowel tissue between first and second electrically-conductive surfaces, applying a clamping pressure to the grasped bowel tissue in a range of about 1 kg/cm2 to about 2.5 kg/cm2, supplying energy to at least one of the first and second electrically-conductive surfaces such that the energy is conducted between the first and second electrically-conductive surfaces and through the grasped bowel tissue to seal the grasped bowel tissue, and monitoring one or more parameters during the supplying of energy to the electrically-conductive surface(s). Instruments, end effector assemblies, generators, and systems suitable for this purpose are also provided.
