    摘要: A stent can be made by injecting a molten reaction mixture into a mold. The mold being in the shape of a radially expandable stent. The reaction mixture can have a reactive species capable of causing polymerization or crosslinking in the reaction mixture upon exposure to radiation. The method can include exposing the reaction mixture to radiation to cause polymerization or crosslinking in the reaction mixture.
