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.
