A system for treating uterine disorders includes a balloon catheter having a cannula with a proximal end and a distal end, and an inflatable balloon secured over the distal end of the cannula. The device includes a heating assembly coupled with the distal end of the cannula and disposed inside the inflatable balloon, and an impeller disposed inside the heating assembly. In one embodiment, the heating assembly includes an elongated heating tube having a heating film covering an outer wall thereof, at least one fluid inlet extending though the outer wall and a fluid outlet located at a distal end of the elongated heating tube. The impeller is rotatable for drawing fluid through the at least one fluid inlet and into the elongated heating tube for heating the fluid, and discharging the heated fluid from the fluid outlet for circulating the fluid throughout the inflatable balloon.
