    • A partially biodegradable stent includes a main net body of hollow cylindrical shape formed of elastically deformable wires interlaced with each other, the net body extending in a longitudinal direction and terminating at open opposite ends, and an auxiliary net portion provided at one of the open opposite ends of the main net body, the auxiliary net portion formed of a biodegradable wire which can be degraded and removed by a bodily fluid. The auxiliary net portion is formed by interlacing the biodegradable wire into a cylindrical shape independently of the main net body or by interlacing the biodegradable wire with the elastically deformable wires at one of the open opposite ends of the main net body.
    • 部分可生物降解的支架包括由互相交错的可弹性变形的线形成的中空圆柱形的主网体,网体沿纵向方向延伸并且在相对的开放端处终止,辅助网部设置在开放的相对的一个 主网体的端部,辅助网部由可由体液降解和去除的可生物降解的线形成。 辅助网部分通过将生物可降解的线交织成独立于主网体的圆柱形形状,或者通过将可生物降解的线与可互换的可变形的线交织在主网体的开放的相对端之一处而形成。
