  • Publication number: 20180369003
    Abstract: The present invention discloses a rolled up radially self-expanding stent comprising at least one transverse expandable member of non-shape memory alloy sheet or wire loops laminated in a polymer and rolled up in a configuration that stores elastic energy and retains flexibility, arranged on a longitudinal axis used to improve the lumen patency of non-vascular body lumens. The radial expansion of the stent is caused by unrolling of the rolled up transverse expandable member during deployment in the body lumen.
