BLOOD VESSEL STENT

Disclosed is a blood vessel stent, comprising a stent body. The stent body is a reticulated tube structure woven by metal wires, wherein the stent body comprises a first stent segment and a second stent segment that are connected in the axial direction, and the mesh density of the first stent segment is different from that of the second stent segment. The blood vessel stent provided in the present invention can improve the treatment effect for involving inferior vena cava and iliofemoral vein stenosis by means of bare sections, can improve the support strength and anti-compression performance for a compression part by means of a dense mesh structure having a larger mesh density, can increase the flexibility and wall attachment performance for a bending part by means of a sparse mesh structure having a smaller mesh density, can adapt to the shapes of blood vessels for different anatomical shapes of blood vessels by means of a diameter variable structure, and is suitable for various blood vessel diameters.
