1. A method for thermally treating tissue comprising:
- providing a probe body having a flow channel extending therein to an outlet in a working end;
introducing a flow of a liquid media through the flow channel; and
applying energy to the tissue by inductively heating a portion of the probe sufficient to vaporize the flowing media within the flow channel causing pressurized ejection of the media from the outlet to the tissue.

Abstract
An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.

9. A medical system for treating tissue, comprising:
-
a probe body having a flow channel extending therein to an outlet in a working end; a coil about at least a portion or the flow channel; and an electromagnetic energy source coupled to the coil, where the electromagnetic energy source induces current in the coil causing energy delivery to a flowable media in the flow channel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
