BLOOD VESSEL IMPLANT

WIPO Patent Application WO/2024/083064

A1

A blood vessel implant, comprising an implant body (110) formed by weaving at least two weaving wires (140) in an interlaced manner. At least one of the weaving wires (140) comprises a core wire and a sleeve wrapped around the core wire, wherein the core wire has a sectional area accounting for 20-35％ of the total sectional area of the weaving wire (140); a first end developing mark (120) on a first end (111) of the implant body (110) is at a distance of 0.1-0.9mm from a distal tip of the first end, and a second end developing mark (130) on a second end (112) is at a distance of 0.5-4.0mm from an end portion of the second end; the ratio of the identification degree of the first end developing mark (120) to the identification degree of the implant body (110) and the identification degree of the second end developing mark (130) under X rays is 0.99: (0.32-0.66): 1.0; and the relative density of a material of the blood vessel implant is betwen 15-25, and the thickness of the blood vessel implant in an X ray direction is between 0.015-0.2mm, such that the developing performance of the two ends of the blood vessel implant under the X rays is superior to the developing performance of the middle section of the implant, and radial support, delivery, opening and adhesion properties of the blood vessel implant can be ensured.
