1. An apparatus for inflating and deflating a catheter having a first expandable membrane, the apparatus comprising:

  • a first console including a pressurized coolant supply;

    a flow sensor in fluid communication with the pressurized coolant supply, the flow sensor for measuring a fluid flow rate;

    a valve in fluid communication with the pressurized coolant supply, wherein the flow sensor and the valve control fluid delivery for inflation and deflation of the first expandable membrane in order to reach a target volume less than a preselected volume threshold;

    the first console having a shut-off valve for interrupting the flow of pressurized coolant from the first console to the catheter if the delivered volume exceeds the preselected volume threshold; and

    an umbilical system for coupling to the catheter and for delivering pressurized coolant to the first expandable membrane.
