Abstract
An absorbable metal stent includes an absorbable metal substrate; the absorbable metal substrate includes a plurality of wave-shaped annular structures and a plurality of axial connecting portions, two ends of each axial connecting portion being connected to two adjacent wave-shaped annular structures, respectively, so as to axially connect the plurality of wave-shaped annular structures; a corrosion-promoting coating is formed on each axial connecting portion, the corrosion-promoting coating containing a corrosion-promoting substance, and the corrosion-promoting substance being selected from at least one of a degradable polymer and a degradable polymer antioxidant; the corrosion-promoting coatings cause the corrosion of the axial connecting portions to occur earlier than the corrosion of the plurality of wave-shaped annular structures. The absorbable metal stent has good bending performance and may prevent the problems of secondary hyperplasia after implantation and stenosis caused thereby.
