Abstract
Disclosed is an intraluminal catheter that includes a flexible elongate shaft configured to be positioned within a body lumen of a patient, and an intraluminal sensor disposed at the distal portion of the shaft that is configured to sense a characteristic within the body lumen. The shaft further comprises a plurality of wires disposed around a lumen, wherein the wires are helically twisted. The wires can be helically twisted in a single direction to form a cylindrical shape. This helical structure is configured to stiffen the flexible elongate shaft for movement into an obstruction within the body lumen without kinking.
