20080243230 | STENT HAVING RADIALLY EXPANDABLE MAIN BODY - A stent made of a material having a low strength and having a main body circumscribing a cylindrical shape and radially expandable from a contracted starting position into a dilated support position, comprising a) a plurality of support segments disposed around the circumference and arrayed on one another in the axial direction each segment being formed by a strut meandering in its coarse structure in its contracted starting position and having alternately opposing meandering curves expandable into the support position made of flexible material; b) a plurality of axial connectors connecting between zenith points of at least a part of the meandering curves in the axial-parallel direction of the support segments; and c) at least one means for stabilizing the strut coarse structure in its contracted starting position against radial expansion and being automatically detachable upon a radial expansion of the stent. | 10-02-2008 |
