Abstract
输尿管支架(1A)由在一端部(21)与另一端部(22)之间的范围内延伸的管体(2)构成。管体(2)包括构成为配置于肾脏的第一弯曲部(31)、构成为配置于膀胱的第二弯曲部(32)、以及在第一弯曲部(31)与第二弯曲部(32)之间的范围内延伸的延伸部(30)。在作为第一弯曲部(31)以及第二弯曲部(32)中的至少一方的对象弯曲部的至少一部分中以第一比例包含作为X射线不透过性的材料的第一材料。对象弯曲部的至少一部分的颜色是第一颜色。在延伸部(30)中以第二比例包含作为X射线不透过性的材料的第二材料。延伸部(30)的颜色是第二颜色。对象弯曲部的X射线透过率与延伸部(30)的X射线透过率不同。
