Claim 15:
16. A system for heating or cooling a patient's blood during a procedure involving extracorporeal blood circulating, the system comprising:
a heater/cooler module including a first pump and a first heater/cooler element fluidly coupled to a primary circuit including a heating circuit path and a separate cooling circuit path, and configured to heat and/or cool a first fluid in the primary circuit, wherein each of the separate heating and cooling circuit paths are fluidly coupled to the first heater/cooler element such that the first fluid when heated by the first heater/cooler element flows from the first heater/cooler element into the heating circuit path and the first fluid when cooled by the first heater/cooler element flows from the first heater/cooler element into the cooling circuit path;
a heat transfer fluid circuit including a secondary circuit configured to provide a second fluid to a target device containing blood therein to heat and/or cool the blood; and
a heat exchanger including at least part of the primary circuit through which the first fluid flows and at least part of the secondary circuit through which the second fluid flows to facilitate heat transfer between the first fluid and the second fluid, wherein the primary circuit and the secondary circuit are separate circuits, such that the first fluid and the second fluid remain separated in the system.
