Abstract
A catheter includes working fluid supply and return lumens through which working fluid circulates to exchange heat with a patient in whom the catheter is positioned. Plural wires arranged in a mesh are located longitudinally along the catheter and engaged therewith. The mesh can be moved between a radially expanded configuration, in which the mesh circumscribes an inner wall of a vessel in which the catheter is disposed and in which blood flowing through the vessel is not significantly impeded from flowing within the mesh past the catheter, and a radially collapsed configuration, in which the mesh lies against the catheter or is closely spaced therefrom to facilitate advancement and retraction of the catheter from the vessel.
