Claim 9:
10. A method of heating and/or cooling blood in a target device via a heater/cooler module including a first fluid in a primary circuit, an integrated pump, a first heater/cooler element, and a heat exchanger, the method comprising:
pumping the first fluid through the primary circuit and the heat exchanger via the pump, the primary circuit including a heating circuit path and a separate cooling circuit path;
heating and/or cooling the first fluid in the primary circuit with the first heater/cooler element, wherein each of the separate heating and cooling circuit paths are fluidly coupled to the first heater/cooler element such that heating the first fluid in the primary circuit and cooling the first fluid in the primary circuit each involve pumping the first fluid through the first heater/cooler element;
providing a second fluid in a secondary circuit that is separate from the primary circuit, such that the first fluid and the second fluid are maintained as separate fluids;
pumping the second fluid through the secondary circuit and the heat exchanger;, facilitating heat transfer in the heat exchanger between the second fluid in the secondary circuit and the first fluid in the primary circuit; and
providing the second fluid to the target device to facilitate heat transfer between the second fluid and the blood.
