Abstract
A catheter has a series of hollow loops arranged along a tube for carrying working fluid from a heat exchange system to exchange heat with a patient in whom the catheter is advanced. The loops when inflated are transverse to the catheter axis and parallel to each other, and circumscribe a hollow passageway through which blood can flow. Blood also flows around the outer perimeters of the loops.
