<p>Thermal treatment apparatus for thermally treating selected tissues of a subject located in or near a body cavity, includes a catheter insertable into the subject's body cavity and having a proximal end formed with an inflatable anchoring section for anchoring the catheter in the body cavity, a distal end to be located externally of the body cavity, and an inflatable heating section adjacent the proximal end to be located near the tissue to be heated. The catheter is formed with passageways extending from the distal end to the inflatable heating section for circulating heated fluid through the inflatable heating section but not through the inflatable anchoring section, and a further passageway from the distal end to the inflatable anchoring section for inflating the inflatable anchoring section with a non-heated fluid. The inflatable heating section and the tissue in its proximity may thus be heated to a desired high temperature without correspondingly heating the inflatable anchoring section and the tissue in its proximity. <IMAGE></p> |
