Abstract
An absorbable iron-based device includes an iron-based matrix and degradable polyester in contact with the surface of the iron-based matrix. The mass fraction of a low-molecular-weight part of the degradable polyester is less than or equal to 5%, and the molecular weight of the low-molecular-weight part is less than 10,000; or the mass fraction of a residual monomer in the degradable polyester is less than or equal to 2%.
