1. A method of applying energy to soft tissue comprising:
- generating a flow of vapor such that the vapor is ejected from a device in a flow of vapor;
generating a second flow of a second media and combining the second media with the vapor where the second media is depressurized; and
introducing the flow of vapor to interfacing soft tissue wherein the vapor and second media deliver energy sufficient to modify the tissue.

Abstract
This invention relates to surgical instruments for applying energy to tissue using a a vapor-to-liquid phase transition which delivers large amount of energy to the targeted tissue. In one embodiment, the system is configured for volumetric removal of tissue by means of high velocity ejection of a vapor media from a first vapor port proximate to soft tissue wherein the vapor-to-liquid phase change of the media applies energy to the tissue. The system provides a second port coupled to a suction source that cooperates with the first vapor port to suction tissue debris from the targeted site.

- 12. A method of applying energy to mammalian tissue comprising the steps of generating a flow of vapor, introducing a flow of vapor into an interface with tissue, and controlling the parameters of the flow for discriminating between first tissue and second adjacent tissues for volumetric removal of the first tissue without volumetric removal of the second tissue.
