1. A vapor therapy device for producing intra-uterine tissue effect, for at least partial insertion into a patient, the device comprising:
a shaft, including a proximal portion and a distal portion;
an in vivo heat generator, near the distal portion of the shaft;
a fluid-expandable medium, near the distal portion of the shaft, and fully sheathing the in vivo heat generator, wherein the fluid-expandable medium comprises:
a pressure barrier layer encompassing an outlet of a fluid-delivery conduit;
a transport layer at least partially encompassing the pressure barrier layer; and
a tissue compliant layer at least partially surrounding the transport layer;
the fluid-delivery conduit, extending between the proximal portion and the distal portion of the shaft, the fluid-delivery conduit comprising the outlet, near the distal portion of the shaft, for providing fluid into the fluid-expandable medium, wherein the in vivo heat generator is configured to heat the fluid inside the fluid-expandable medium.
