wherein the tube structure includes a plurality of cuts extending transversely into the tube structure, each cut forming one or more beams defined by a remaining section of tube material, each beam connecting two adjacent rings of tube material,
wherein the first section of the tube structure includes two or more beams between adjacent rings, the second section of the tube structure includes a single beam between adjacent rings, and the third section includes two or more beams between adjacent rings,

wherein a stiffness of the tube structure is continuous across a transition between the first and second sections, and
wherein a thickness of a most proximal ring of the second section is greater than a thickness of a most distal ring of the first section.
