Claim Text:
1. A method for a thermally-mediated therapy for treating tissue, the method comprising providing an instrument having a selected media in a liquid form; applying energy to the selected media such that the selected media increases in volume causing a liquid-to-vapor phase transition of the selected media to a vapor form; delivering a pressurized vapor stream of the selected media to flow from the instrument while controlling a pressure of the pressurized vapor stream; and directing the pressurized vapor stream of the selected media to a tissue site such that contact with the tissue site causes a vapor-to-liquid phase state change of the pressurized vapor stream to the liquid form and where the vapor-to-liquid phase state change releases a thermal energy substantially equal to a heat of vaporization of the selected media to the tissue site to cause ablation of the tissue site.
