Abstract
An absorbable iron-based implantable device, including an iron-based substrate and an iron absorption promoter that is attached to the iron-based substrate. The iron absorption promoter is a polymer containing an antioxidant structural unit on the molecular chain thereof. The antioxidant is gradually released as the iron absorption promoter is gradually degraded or broken, and may promote the absorption of iron.
