Abstract: Devices and methods for cooling all or part of the body of a human or animal subject by inserting a heat exchange catheter into the subject's body and infusing into or through the catheter a heat exchange medium that contains liquid phase matter and frozen solid phase matter, wherein at least some of the solid phase matter melts while in the catheter.

Abstract: A peristaltic pump has an arcuate raceway with a partially concave inner surface extending through an arc of at least one hundred eighty degrees (180°). The arc defines a midpoint, and a rotor faces the inner surface of the raceway and is both rotatable relative to the raceway and translationally movable relative to the raceway between a pump position, wherein the rotor is spaced from the midpoint a first distance, and a tube load position, wherein the rotor is spaced from the midpoint a second distance greater than the first distance. A motor is coupled to the rotor to rotate the rotor plural are rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. The motor is prevented from stopping at a predetermined angular position to facilitate loading and unloading tubing.

Abstract: A closed loop catheter useable for heat exchange is manufactured by forming a plurality of generally transverse bore holes though a flexible, multilumen catheter body, lacing a tube trough the bore holes so that loops of the tube protrude from the catheter body, connecting one end of the tube to an inflow lumen of the catheter and connecting the other end of the tube to an outflow lumen of the catheter. A heated or cooled heat exchange medium may then be circulated through the tube while the catheter is inserted in the vasculature of a subject, thereby resulting in heat exchange between the subject's flowing blood and the heat exchange medium being circulated through the tube.

Abstract: A working fluid cassette for an intravascular heat exchange catheter includes a frame holding two closely spaced, square polymeric membranes along the sides of which are disposed inlet and outlet tubes. Working fluid from the catheter is directed from the inlet tube between the membranes to the outlet tube. The cassette is closely received between two refrigerant cold plates to exchange heat with the working fluid, which is circulated back to the catheter.

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