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 heat exchange system for exchanging heat with working fluid from an intravascular heat exchange catheter or an external heat exchange pad includes a working fluid that circulates between the catheter or pad and a fluid cassette, and a refrigerant system that flows against the outer sides of cold plates between which the cassette is disposed.
