Abstract: An electrosurgical assembly is disclosed, the assembly having two, three or more electrodes configured to provide advantageous tissue removal and precision for conducting electrosurgical procedures, including improved ablation and coagulation of tissue. The electrodes are configured and arranged so that energy can be applied in a highly uniform and precise fashion, depending upon the application. In addition, the electrosurgical assembly allows flexibility in use by, in some embodiments, allowing selective switching of the active and return electrodes, and also selective switching between ablation and coagulation modes. In certain embodiments the invention includes one or more electrodes having the ability to undergo changes in shape.
