Abstract: An enclosure or plenum (50) that supports a looped pump tube (44) is hingedly connected to a framed thin-walled heat exchange bag (54) through which working fluid from an intravascular heat exchange catheter (12) flows. The frame with bag can be inserted between cold plates (31) to exchange heat with the working fluid flowing through the bag. With the framed bag between the plates, the looped pump tube (44) from the enclosure or plenum is receivable in the raceway (32) of a peristaltic pump (30), which pumps working fluid through the system.

Abstract: Cold plates (30, 32) through which refrigerant flows define a slot (34) between them that can receive a cassette (50) through which sterile working fluid with a relatively low flow rate flows from an intravascular heat exchange catheter (12). The working fluid from the catheter (12) is heated or cooled by heat exchange with the cold plates (30, 32) through the walls of the cassette (50) to maintain the sterility of the working fluid. On the other hand, high flow rate working fluid chambers surround the cold plates (30, 32) and non-sterile working fluid from an external heat exchange pad (14) flows through the high flow rate working fluid chambers to exchange heat through direct contact with the cold plates (30, 32).

Abstract: Cold plates (30, 32) through which refrigerant flows define a slot (34) between them that can receive a cassette (50) through which sterile working fluid with a relatively low flow rate flows from an intravascular heat exchange catheter (12) or external pad (18). The slot (34) may have bulge cavities (R1, R2) along the edges to permit the membrane of the cassette to expand and thus establish fluid supply and return passageways.

Abstract: A peristaltic pump has an arcuate raceway (32, 130) with a partially concave inner surface (36, 136) extending through an arc of at least one hundred eighty degrees (180). The arc defines a midpoint (38/138), and a rotor (34/134) faces the inner surface of the raceway (32, 130) and is both rotatable relative to the raceway (32, 130) and translationally movable relative to the raceway (32, 130) between a pump position, wherein the rotor (34/134) is spaced from the midpoint (38/138) a first distance, and a tube load position, wherein the rotor (34/134) is spaced from the midpoint (38/138) a second distance greater than the first distance. A rotor motor (58) is coupled to the rotor (34/134) to rotate the rotor and rollers (46, 48) are arranged on the rotor to contact tubing disposed between the rotor (34/134) and the raceway (32, 130) when the rotor (34, 134) is in the pump position. A manual positioning mechanism (70) or a loading motor (140) can move the rotor (34 or 134) toward and away from the raceway (32, 130).

Abstract: A heat exchange system for exchanging heat with working fluid from an intravascular heat exchange catheter (12) or an external heat exchange pad (18) includes a working fluid that circulates between the catheter (12) or pad (18) and a fluid cassette (50), and a refrigerant that flows against the outer sides of cold plates (30, 32) between which the cassette (50) is disposed.

Abstract: A working fluid cassette for an intravascular heat exchange catheter (12) includes a frame (52) holding two closely spaced, square polymeric membranes (66, 68) in tension. Working fluid from the catheter (12) is directed between the membranes (66, 68). The cassette is closely received between two refrigerant cold plates (30, 32) to exchange heat with the working fluid, which is circulated back to the catheter (12).
