Abstract
Provided are an implanted medical device (1) and preparation method thereof, and an implanted medical device preform for preparing the implanted medical device (1). The implanted medical device (1) comprises a metal basal body (21) and a polymer film layer (22) covering the surface of the metal basal body (21) and preventing endothelium growth and covering, wherein at least a part of the surface of the metal basal body (21) is provided with a surface-modified layer (211) which contains doped ions, and the metal basal body (21) is connected to the polymer film layer (22) by the doped ions. Since the metal basal body (21) may be bonded to the polymer film layer (22) by the doped ions, the polymer film layer (22) is unlikely to separate during delivery, therefore effectively preventing endothelium growth and covering in vivo.
