Abstract:
An absorbable iron-based alloy implantable medical device includes an iron-based alloy matrix, a degradable polymer coating disposed on the surface of the iron-based alloy matrix, and a corrosion inhibition layer disposed on the surface of the iron-based alloy matrix. The corrosion inhibition layer can delay early-stage corrosion of the iron-based alloy matrix, ensure mechanical performance of a medical device in the early stage of the implantation, prevent degradation of a polymer in the early stage of the implantation of the medical device, and reduce the usage of the degradable polymer, thereby reducing risks of inflammatory reactions.

Claim (Index 15):
The absorbable iron-based alloy implanted medical device according to  claim 11 , wherein the degradable polymer is selected from degradable polyester and/or degradable polyanhydride; the degradable polyester is selected from the group consisting of polylactic acid, polyglycolic acid, poly(lactic acid-glycolic acid), polycaprolactone, polyhydroxyalkanoate, polyacrylate, poly(ethylene succinate), poly(\u03b2-hydroxybutyrate) and polyethylene glycol adipate, or is a physical blend of at least two of the polylactic acid, the polyglycolic acid, the poly(ethylene succinate), the poly(\u03b2-hydroxybutyrate), the polycaprolactone, the polyethylene glycol adipate, a polylactic acid-glycollic acid copolymer and a polyhydroxybutyrate-pentanoate copolymer, or is selected from the group consisting of copolymers formed by copolymerizing at least two of monomers forming the polylactic acid, the polyglycolic acid, the poly(ethylene succinate), the poly(\u03b2-hydroxybutyrate), the polycaprolactone, the polyethylene glycol adipate, the polylactic acid-glycollic acid copolymer and the polyhydroxybutyrate-pentanoate copolymer; and the degradable polyanhydride is selected from the group consisting of poly1,3-bis(p-carboxyphenoxy)propane-sebacic acid, poly(erucic acid dimer-sebacic acid) or poly(fumaric acid-sebacic acid), or the degradable polymer is a copolymer formed by copolymerizing at least two of monomers forming the degradable polyester and the degradable polyanhydride.
