An intravascular stent includes a plurality of first stent rings, a plurality of second stent rings and a cover member. Each of the first stent rings and each of the second stent rings is formed by a metal wire with multiple bends. The first stent rings are arranged along an axis, and the second stent rings are disposed at two ends of the first stent rings along the axis. The cover member covers the first stent rings and the second stent rings. A dimension of an area surrounding by each of the second stent rings is larger than that of an area surrounding by each of the first stent rings, so that a central zone formed by the first stent rings has smaller diameter and two end zones formed by the second stent rings are disposed at two sides of the central zone and have larger diameters.一種血管支架,包括多個第一支架環、多個第二支架環及包覆材。各第一支架環由多段彎折的金屬線所環繞而成,這些第一支架環沿著一軸線排列。各第二支架環由多段彎折的金屬線所環繞而成,這些第二支架環沿著軸線A配置於這些第一支架環的兩端。包覆材覆蓋這些第一支架環與這些第二支架環。各第二支架環所環繞出的尺寸大於各第一支架環所環繞出的尺寸,由第一支架環形成直徑較小的中央區,位於中央區兩端且由第二支架環形成直徑較大的兩個端部區。A‧‧‧軸線100‧‧‧血管支架110‧‧‧第一支架環111‧‧‧第二支架環112‧‧‧中央區114‧‧‧端部區120‧‧‧包覆材130‧‧‧嵌鉤組件132‧‧‧第三支架環134‧‧‧鉤部140‧‧‧圓珠
