Electrosurgical working end with resistive gradient electrodes

摘要

An electrosurgical working end and method for transecting an anatomic structure along a targeted line and for creating a thermal welds along either of both transected tissue margins, for example for use in a partial lung resection procedure. In one embodiment, the working end provides elongate curved or linear guide members that can be positioned on opposing sides of the targeted anatomic structure. The working end carries a slidable member with interior channels that receive the guide or jaw members. The electrode or electrodes carried by of working end define a resistive gradient for creating controlled Rf ohmic heating in the engaged tissue.
