Abstract
A system and method for tissue thermotherapy including a source for generating a vapor phase media for treating a space in a human body, such as and intraluminal or intracavity space. The system further includes a filtering member for allowing a recirculation of flowable media about an interface with tissue, wherein the filtering member prevent ablation detritus from interfering with media outflows from the working end.

10. A method for locally treating a region of a wall of an organ, vessel, cavity or lumen the method comprising:
-
positioning a device proximate to a targeted tissue of the wall of a body organ, cavity, vessel or lumen; and introducing a flow media to the vicinity of the targeted tissue wherein a release of energy from a phase change of a water vapor portion of the flow media ablates the targeted tissue. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A device for locally treating a region of a wall of an organ, vessel, cavity or lumen comprising:
-
a vapor delivery tool configured to deliver flowable media from a working end outlet to an interface with a targeted tissue in the interior of a patient'"'"'s body; an inlet in the working end for allowing a return flow of flowable media; and a filter member carried by the working end configured to prevent ablation detritus from entering the inlet. - View Dependent Claims (22, 23, 24, 25, 26)

- 28. The method of claim 27 further comprising applying an aspiration source through an aspiration port to the treatment cavity to aspirate the flow media.
-
33. The method of claim 27 wherein the flow media is delivered to a surface of the region of tissue.
-
34. The method of claim 27 wherein the flow media is injected into a subsurface portion of the region of tissue.
-
35. The method of claim 27 wherein the flow media is delivered to a surface of the region of tissue and injected into a subsurface portion of the targeted tissue.
-
36. The method of claim 27 where delivering the flow media into the cavity comprises circulating the flow media within the cavity.
