ABSTRACT:
A cryoablation system for performing endometrial ablation comprising an elongated tubular cannula having a proximal end, a distal end, and a longitudinal axis, an expandable balloon extending from the distal end of the cannula and fluidly connected to a source of heat transfer fluid by at least one fluid path, a pump for circulating the heat transfer fluid into and out of the balloon, a probe handle coupled to the proximal end of the cannula and in fluidic communication with the balloon through the cannula, and a heat exchanger for varying the temperature of the heat transfer fluid, wherein the heat exchanger is fluidly connected to a secondary refrigerant source, and wherein the heat exchanger comprises an outer tubular wall and a plurality of fins extending from the tubular wall toward the interior portion of the heat exchanger.
