Abstract
This invention relates to surgical instruments for applying energy to tissue using 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.
