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 3):
The absorbable iron-based alloy implanted medical device according to  claim 1 , wherein the tannic acid chemical conversion film covers part of the surfaces of the iron-based alloy substrate, and the degradable polymer layer covers at least part of the surfaces of the tannic acid chemical conversion film, or the tannic acid chemical conversion film and the degradable polymer layer both cover different surfaces of the iron-based alloy substrate in a staggering manner, or the degradable polymer layer covers at least part of the surfaces of the tannic acid chemical conversion film and at least part of non-covered regions.
