Abstract


Biodegradable magnesium alloy stents are a new generation of vascular stents which can open up blocked blood vessels at an early stage, then degrade and be absorbed by the body at a suitable rate after the vascular has been repaired. Mg alloys are excellent materials for vascular stents benefit from their sufficient mechanical properties and good biocompatibility. At present, Mg alloy is also used as a green material in the research of vascular stents due to its biodegradable property. In this paper, based on the research situation of degradable Mg alloy stents in recent years, the research history, degradation mechanism, structural design and basic research experiments of Mg alloy stents are reviewed.
