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.
