Abstract: Various embodiments of multielectrode radiofrequency (RF) ablation probes are described herein that disclose methods and apparatus for improved control and predictability of the size and shape of RF thermal electrocoagulations. The features of the invention include the ability to make irregularly shaped ablations in order to conform to irregularly shaped target tissue volumes, and to make very large ablations without the requirement for electrode cooling.

Abstract: A cannula having a hollow metal tube for injection of liquids such as an anesthetic, or RF energy, into a patient. A thermocouple or other temperature sensor is located at the bare tip of the cannula, and a wire for the temperature sensor extends along the length of the cannula, preferably in a groove formed in the tube, or through a passageway formed in the tube. An outer insulation layer covers the tube and wire. Thus, a single device serves as both a cannula and an electrode.
