Method and apparatus for vaginal protection from hot fluids during endometrial ablation treatment
A fluid collection device for collecting fluid leaking from the uterus of a patient during endometrial ablation includes a collar which is mounted on a catheter of an endometrial ablation device. The collar defines with the catheter of the ablation device an interior fluid collection area. The collar has a first open end which allows leaking fluid to pass therethrough into the collection area, and is dimensioned so as to be closely contactable with the cervix of the patient undergoing treatment. Any fluid leaking from the uterus of the patient during the ablation process will be captured by the collection area of the collar. A drain tube connected to the collar removes any fluid collected by the collar. The fluid collection device removes any fluid passing from the uterus to the cervix before it may enter the vagina of the patient to cause burns or damage to the vaginal tissue lining.

ActiveUS20120245583A1Energy delivery can be efficientlyLow efficiencyDiagnosticsSurgical instruments for heatingEngineeringEndometrium
A wall of a uterus is ablated by expanding a structure in the uterus and applying energy across the wall of the structure into the uterine wall. An exterior surface of the structure conforms to an inner wall of the uterus, and the energy may cause vapor to collect between the wall and the structure. The vapor is released by providing a barrier to release which is inflated at a pressure above which the barrier at least partially collapses to allow the vapor to leave the uterus.
