Abstract
An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedances, thicknesses and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue in the compression zone between first interfacing surface and second interfacing surfaces. The compression zone is formed by an insulator which forms a compression ridge in one of the interfacing surfaces and separates first and second electrically opposite electrodes. A preferred application of the invention is in a cutting instrument wherein a hemostatic line is formed using RF along a cut line.
