Rf ablation systems with a bipolar rf electrode and methods for making and using

Abstract

An RF ablation system can include a bipolar RF electrode that has two electrodes. Some bipolar RF electrodes can include a metal tube forming one of the electrodes. The metal tube can have cuts to facilitate bending of the metal tube. Some bipolar RF electrodes can include a multi-lumen tube for the conductors. Some multi-lumen tubes can be made of a relatively high durometer material to provide column strength to the bipolar RF electrodes. Some RF ablation systems can include an adapter for a RF generator to connect each electrode to a different channel. A variety of arrangement of the channels of the RF generator and the conductors of the bipolar RF electrode can be used to couple the electrodes and a temperature sensor to the RF generator.
