The invention discloses a coated stent, comprising a stent section, a coat and a reinforcement; wherein, two ends of a metal wire are connected to form the reinforcement which is fixed on the coat. The invention is characterized in that: since the coated stent adopts the independent reinforcement, the reinforcement is separated from the stent section, avoiding the risk that in prior art the integral connection of the reinforcement and the front and end stent sections can lead to fracture; furthermore, the hindrance produced in the course of releasing and assembling the whole stent is reduced,which is helpful for the releasing and assembling of the coated stent. The invention also discloses another coated stent comprising a stent section and a coat; wherein, two ends of a metal wire are connected by laser welding to form the stent section. Since two ends of the metal wire in each stent section are not fixedly connected, prior coated stent can lead blood damage; therefore, the risk is avoided.
