Claim 12:
13. A method of inflating and evacuating a liner within a uterine cavity, comprising:
positioning the liner within the uterine cavity, wherein the liner is adapted to conform to a contoured tissue surface;
positioning a first valve in an open position and a second valve in a closed position, wherein the first valve is positioned along a pump output pathway and the second valve is positioned along a pump input pathway;
drawing air through the second valve and into the liner via a pump which is fluidly coupled through the pump output pathway while the liner is within the uterine cavity such that the liner is expanded at an initial rate to an initial volume and then expanded at a subsequent rate which is more gradual than the initial rate to a volume having a predetermined pressure level which is sufficient to open the uterine cavity thereby minimizing pain experienced by a patient;
introducing a cryogenic fluid through an infusion line and into the liner until a treatment of the uterine cavity is completed;
positioning the first valve in a closed position and the second valve in an open position; and
evacuating the cryogenic fluid from the liner via the pump such that the cryogenic fluid is exhausted into an ambient environment via the first valve.
