Abstract
The embodiment of the present application provides a kind of iliac vein stent, wherein, iliac vein stent has the morphology of collection and the morphology of expansion, the iliac vein stent includes: first part, it is suitable for when the morphology of collection is switched to the morphology of expansion, the first deformation variable along the axial direction of the iliac vein stent is generated;Second part, along the axial direction of the iliac vein stent with the first part is connected, it is suitable for when the morphology of collection is switched to the morphology of expansion, the second deformation variable along the axial direction of the iliac vein stent is generated;Wherein, one of the first deformation variable and second deformation variable is length increase deformation variable, and the other is length reduction deformation variable.The above technical scheme is used, and the deviation of iliac vein stent in the process of use can be reduced.
