THERMAL HEATING ELEMENT FOR USE WITH ENDOMETRIAL ABLATION

A device for endometrial ablation includes a selectively expandable bladder configured for insertion through a cervical canal of a patient and into a patient's cervix. The selectively expandable bladder defines an interior volume for receiving a thermally conductive medium which, when introduced into the interior volume, expands the selectively expandable bladder against the uterine tissue of the cervix. One or more insulative substrates is operably disposed within the interior volume and supports a thermal assembly on the one or more insulative substrates. The thermal assembly couples to an energy source and is configured to conduct thermal energy to a thermally conductive substrate upon activation of the thermal assembly, which, in turn, heats the thermally conductive medium in contact with the thermally conductive substrate to treat the uterine tissue of a patient.
