1. A method of delivering cryogen to a cryoprobe, said method comprising the steps of:
providing a device containing the cryogen, said device having one or more ports;
providing a pump submersed within the cryogen;
providing a plurality of pressurized apparatuses within said device and coupled to said pump, each of said plurality of pressurized apparatuses having an immersion heater contained therein, at least one inlet port, and at least one outlet port;
providing an instrument outside said device for use in cooling processes, said instrument connected to one or more supply lines which interconnect with said device;
activating a first pressurized apparatus of said plurality of pressurized apparatuses to form a first volume of pressurized cryogen;
directing said first volume of pressurized cryogen to said instrument through said one or more supply lines;
directing a second volume of cryogen to a second pressurized apparatus of said plurality of pressurized apparatuses; and
activating a third pressurized apparatus of said plurality of pressurized apparatuses to form a third volume of pressurized cryogen wherein the step of directing the first volume of pressurized cryogen to said instrument, the step of directing the second volume of cryogen to the second pressurized apparatus, and the step of activating the third pressurized apparatus to form the third volume of pressurized cryogen are performed simultaneously.
