Absorbable Iron-based Alloy Medical Device Implant |
| abstract |
An absorbable iron-based alloy medical device implant, comprising an iron-based alloy substrate ( 11 ) and a degradable polymer ( 13 ) provided on a surface of an iron-based alloy substrate ( 11 ), and a zinc-containing protective member ( 12 ) provided on the surface of the iron-based alloy substrate ( 11 ). The zinc-containing protective member ( 12 ) is either a zinc compound or a mixture comprising the zinc compound and at least one of a phosphate-containing compound, a degradable binder, or a water-soluble binder. The weight ratio of the zinc compound in the mixture is ≥20% and <100%. The zinc-containing protective member ( 12 ) can delay corrosion of the iron-based alloy substrate ( 11 ) during an early stage of medical device implantation. The iron-based alloy substrate ( 11 ) is essentially corrosion-free during the early stage of medical device implantation, and is therefore able to satisfy clinical requirements of mechanical performance during the early stage of medical device implantation. |
