Abstract:
1. A stent, having a main body circumscribing a cylindrical shape having an axis and radially expandable from a contracted starting position into a dilated support position, comprising: (a) a plurality of flexible support segments, spaced around the circumference of the main body and arrayed in an axial direction, each support segment being formed by a strut meandering in its coarse structure in its contracted starting position, and having alternately opposing meandering curve sections expandable into the dilated support state; (b) a plurality of axial connectors each connecting between a zenith point of one meandering curve section and a second meandering curve section in the axial-parallel direction of the support segments; and (c) a plurality of stabilizer elements for stabilizing the main body in a contracted starting state against undesired radial expansion the plurality of stabilizer elements comprising: a plurality of x-ray marker projections connected to the struts and projecting from a terminal one of the flexible support segments of the main body and spaced around the circumference of the main body, the x-ray marker projections being coated with marker polymer, the marker polymer forming a ring projecting from the terminal one of the flexible support segments of the main body connecting the x-ray marker projections in the contracted state and automatically detachable upon radial expansion of the stent into the dilated support position.
