ABSTRACT:
Systems and methods are provided for applying a high frequency voltage in the presence of an electrically conductive fluid. High frequency voltage is then applied between the active electrode(s) and one or more return electrode(s) to volumetrically remove or ablate at least a portion of the target tissue. In one embodiment a tissue treatment surface includes spacers or a chamber for containing the electrodes.
