`ABSTRACT
`
`The hinge stent is a balloon-expandable or self-expandable
`intravascular endoprosthesis used for treatment of vascular
`injury. The hinge stent is formed of a single stent section or
`of multiple stent sections joined together. Each stent section
`has a node and strut structure extending throughout in order
`to uncouple expansion forces of the stent to hold a blood
`vessel outWard from crush forces that resist the formation of
`an oval shape during a crush deformation. Each node
`includes a hinge Which is joined via a transition region to a
`strut. The hinge can bend in the direction of a uniformly
`curved surface of the stent but not in the radial direction. The
`strut can bend in the radial direction but not in the uniformly
`curved surface of the stent. The Widths, lengths, and radial
`dimensions of the hinges and struts provide a balloon
`expandable hinge stent that is non-crushable. For a self
`expandable stent the hinge and strut dimensions provide
`expansion forces that are controlled independently from
`crush forces. The hinge stent can be formed of a high
`modulus metal With expansion properties being determined
`by the hinge dimensions and crush properties being deter
`mined independently by the design of the strut dimensions.
`The node and strut structure of the hinge stent provides for
`?exibility in traversing along tortuous passages.
