Abstract: Flexible elongate devices and methods include an articulable body portion and a control structure attached with one or more pull wires that control articulation of the articulable body portion. The control structure includes a metallic material that defines a sealing surface functionalized by a primer. A polymer material disposed onto the sealing surface of the control structure creates a seal between the control structure and polymer material. Flexible elongate devices and methods also include a control structure and a pull wire configured to control articulation of the flexible elongate device. The control structure includes a plurality of control segments stacked along a longitudinal axis, where each of the control segments define a pull wire aperture, where pull wire apertures of adjacent control segments are offset relative to one another, such that a portion of the pull wire extending through the pull wire apertures has a non-linear shape.

Abstract: Flexible elongate devices include an elongate body having an articulable body portion and an axial support structure within the articulable body portion. The axial support structure can include a plurality of transverse support segments with tubular struts disposed between the support segments. The flexible elongate devices can include a component line that has a helical shape within the articulable body portion.
