Abstract
A catheter has a hollow conduit through which working fluid from a heat exchange system flows. The conduit in turn is configured to extend along a longitudinal central axis in a continuously varying non-constant azimuthal orientation so that it defines a non-round enclosed passageway through which blood can flow to exchange heat through a wall of the conduit with the working fluid flowing within the conduit.
