1. A method for treating the esophagus at a treatment location comprising a diseased mucosal lining, the method comprising:

  • introducing an expandable sizing member at the treatment location within the esophagus;

    substantially unfolding surface contours of a wall of the esophagus at the treatment location by expanding the sizing member;

    measuring a substantially unfolded esophageal luminal dimension at the treatment location while the sizing member retains the contours of the wall of the esophagus in a substantially unfolded condition;

    removing the sizing member from the patient;

    selecting an electrode structure with a pre-selected deployed state which corresponds to the measured esophageal luminal dimension;

    after removal of the sizing member and while maintaining the sizing member outside of the patient, introducing and deploying the selected electrode structure to the pre-selected deployed state to engage the substantially unfolded esophageal wall at the treatment location; and

    delivering energy to an electrode of the electrode structure for treatment of a portion of the diseased mucosal lining of the esophageal tissue at the treatment location.
