1. A method for delivering radiofrequency current to endometrial tissue, comprising:
deploying a triangular dielectric wall surrounding an interior chamber in a patient's uterus;
providing an electrically conductive plasma in the interior chamber of the dielectric wall;
capacitively coupling a radiofrequency current through the plasma and across the dielectric wall into the endometrial tissue;
wherein providing the electrically conductive plasma comprises converting a neutral gas into the electrically conductive plasma;
wherein converting the neutral gas into the electrically conductive plasma comprises flowing the neutral gas into the interior chamber; and
wherein radiofrequency current is capacitively coupled to the neutral gas by a first polarity electrode within the interior chamber.
