at least two expandable rings, including:
longitudinally extending beams spaced circumferentially around each expandable ring of the at least two expandable rings;
wherein at least one of the beams on each expandable ring of the at least two expandable rings includes a throughbore extending longitudinally through the beam;
an expandable strut extending between each of the beams;
the at least two expandable rings aligned along a longitudinal axis of the sheath and coupled together along a coupling member passing through each of the at least two expandable rings to form an elongated tubular structure;
wherein the coupling member extends through the throughbore;
