1. a flexible stent, comprising:

  • One pillar component, it is along the axle screw winding of described support, and described crossette component comprises multiple strut assemblies;

    AndOne spiral part, it comprise multiple shoulder to shoulder, other screw assembly individual, described spiral part with the equidirectional of the described crossette component axle screw winding along described support;

    Wherein each other screw assembly extends and is connected between a circle strut assemblies and next circle strut assemblies;

    Wherein said screw assembly is elongated when a compressive state;

    Wherein when this compressive state, the size in the gap between adjacent helical elements is between 0 and the size of described gap in a deployed condition;

    Wherein said support is longer than it when this deployed condition when this compressive state;

    The radiation-curable shape expansion upon deployment of described spiral part, and be compressible, easily extensible and flexible when being in described deployed condition;

    And the leg portion be positioned on the either side of described spiral part, each described leg portion comprises the strut assemblies axially aligned, described strut assemblies has a first end of the described screw assembly being connected to described spiral part, and described leg portion is the expansion of radiation-curable shape upon deployment.
