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.

Intravascular systems, devices, and methods having a captively-held filling are provided. An intravascular imaging device can include a flexible elongate member including a lumen having a proximal portion and a distal portion; a drive cable disposed within the lumen such that an ultrasound transducer coupled to the drive cable is positioned within the distal portion of the lumen; and a filling captively held within at least the distal portion of the lumen and surrounding the ultrasound transducer, the filling facilitating transmission and receipt of ultrasound signals. A method of manufacturing an intravascular imaging device can include acquiring a flexible elongate member including a lumen; inserting a drive cable into the lumen, a rotational ultrasound transducer being coupled to the drive cable; inserting a filling that facilitates transmission and receipt of ultrasonic signals into the lumen such that the filling surrounds rotational ultrasound transducer; and sealing the filling within the lumen.
