Fig 1 a, Schematic of collapse finite element simulation. The force is applied on the upper surface to compress the stent between two rigid surfaces; the displacement and the force are measured in each increment. b-d, Collapse finite element simulation results, deformed vs initial configuration of (b) Cook Vena ring, (c) Cook Z ring, and (d) Wallstent one pitch. e, Collapse force vs displacement ratio (Z/R).

Fig 2 Radial pressure of each stent. The horizontal axis illustrates the vein diameter and the vertical axis is the magnitude of radial pressure that is applied by the stent to the vein wall at the contact area (strut’s outer surface).
