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 links longitudinally stacked on one another, where each of the links includes a body defining a plurality of pull wire openings, an outwardly protruding hinge, and a socket. The socket is circumferentially offset relative to the hinge and configured to receive the hinge of one of the links therein. The flexible elongate device can include a distal member disposed at a distal end of the axial support structure, a proximal member disposed at a proximal end of the axial support structure, and a braid sheath surrounding the axial support structure within the articulable body portion, where ends of the braid sheath are coupled to the distal and proximal members.

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.
