Abstract
An electrosurgical hemostatic instrument is provided in which the coagulation status of tissue engaged by two elements delivering electrosurgical energy to tissue may be observed. A preferred embodiment of the invention provides a bipolar endoscopic clamping, coagulation and cutting device. The end effector of the device includes interleaved winged electrodes which act to support the tissue and to provide visual access to the tissue as it is being treated. The winged electrodes are interspersed along the outside of the end effector.
