Abstract
An electrode assembly for use with an instrument for sealing and cutting vessels and/or tissue is provided. The assembly includes a pair of opposing first and second jaw members. Each jaw member includes at least one electrically conductive tissue sealing surfaces extending along a length thereof. Each tissue sealing surface is adapted to connect to a source of electrosurgical energy to effect a tissue seal. An insulator is disposed adjacent to the at least one the electrically conductive sealing surfaces. The jaw members include an electrically conductive cutting element which effectively cuts tissue within pre-defined cutting zone between the jaw members. The polarity of the cutting element and electrically conductive sealing surfaces may be manipulated depending upon whether tissue sealing or tissue cutting is desired.
