Endoscopic surgical instruments are provided that have bipolar electrodes on opposing movable members (18, 19) for passing a high frequency current through tissue for simultaneously severing or manipulating the tissue and causing hemostasis of the tissue. An electrically insulating material is interposed between the movable members (18, 19) so that the electrodes (18, 19) are spaced apart from 0.002 to 0.050 inches and the current passes between the opposing electrodes (18, 19) through the tissue. Methods of endoscopically achieving hemostasis while simultaneously, manipulating and cutting tissue are also provided. Use of a constant voltage high frequency power supply to deliver current to the tissue to cause hemostasis is described in conjunction with those methods.
