Abstract:
Absorbable iron-based alloy implanted medical device and manufacturing method thereof. The iron-based alloy implanted medical device comprises an iron-based alloy substrate ( 11 ), a degradable polymer layer ( 13 ) disposed on a surface of the iron-based alloy substrate ( 11 ), and a tannic acid chemical conversion film ( 12 ) disposed on a surface of the iron-based alloy substrate ( 11 ). After the medical device is implanted into a body, the tannic acid chemical conversion film ( 12 ) is configured to protect the iron-based alloy substrate ( 11 ) coated thereby from being in contact with a body fluid, thereby ensuring that the device meets a clinical mechanical property requirement in the early stage of implantation. Furthermore, the iron-based alloy implanted medical device has a decreased size, and produces a decreased amount of a corrosive product after being implanted, facilitating faster absorption or elimination of the corrosive product.

Claim (Index 10):
The manufacturing method of the absorbable iron-based alloy implanted medical device according to  claim 9 , wherein the concentration of the tannic acid solution is 2 to 10 g/L, a reaction temperature is 15 to 45\u00b0 C., and reaction time is 5 to 60 min.
