Abstract:
An absorbable implantable medical device made of iron-based alloy, including a base made of iron-based alloy and a complex, wherein the complex includes a complexing agent. In a physiological solution, the base made of iron-based alloy can react with the complexing agent to generate a water-soluble iron complex having solubility in the physiological solution of no less than 10 mg/L. A corrosion product generated after the absorbable implantable medical device made of iron-based alloy is implanted in a human body can be quickly metabolized/absorbed by the body.
