1. A system for inflating and evacuating a liner, comprising:
an expandable liner configured for positioning within a uterine cavity;
an infusion line in fluid communication with the liner;
a pump in fluid communication with the liner;
a pump output pathway fluidly coupling the pump and the liner;
a pump input pathway fluidly coupling the pump and the liner;
a first valve positioned along the pump output pathway and configurable between an open position and a closed position;
a second valve positioned along the pump input pathway and configurable between an open position and a closed position;
a controller in communication with the pump; and
wherein the liner is expandable via the pump with air received through the second valve when the second valve is in the closed position and the first valve is in the open position such that the controller is programmed to expand the liner with air according to an algorithm wherein an initial increase in pressure is followed by a controlled increase in pressure which is more gradual than the initial increase in pressure until a volume having a predetermined pressure level is reached which is sufficient to open the uterine cavity thereby minimizing pain experienced by a patient,
wherein the liner is evacuated via the pump when the second valve is in the open position and the first valve is in the closed position such that a fluid within the liner is exhausted via the first valve.
