The present invention discloses an artificial blood vessel stent, which can minimize the diameter of a stent insertion device because the diameter (profile) thereof is uniform and small over the entire length upon being loaded, and accordingly can be easily placed in a branched portion of a blood vessel using a puncture method. The artificial blood vessel stent comprises: (I) an artificial blood vessel body 1 in which the upper end part is formed with a single cylindrical shape or partially cylindrical shape and the lower end part is divided into two small cylindrical shapes or partially cylindrical shapes having different lengths; (II) a cylindrical first stent member 2 connected to the upper end of the artificial blood vessel body and being expandable; (III) a cylindrical second stent member 3 connected to the shorter side of the lower end part of the artificial blood vessel body and being expandable; and (IV) a cylindrical third stent member 4 inserted into the longer side of the lower end part of the artificial blood vessel body, so that the upper end surface coincides with the lower end surface of the second stent member, and being expandable. |
