A multilayer degradable stent with shape memory property is composed of two or more layers of degradable material, wherein one layer is of a degradable polymer material with shape memory property, i.e., shape memory layer, and another layer is of a degradable metal material or a degradable polymer material with excellent radial support capability, i.e., support layer. The preparation method of the degradable stent is also described. The stent not only has low retraction after expansion, but also does not introduce external heat. At the same time, the stent has support force high enough to support a narrowed vessel, and effectively reduces the chances of occurrence of a complication such as inflammation and restenosis etc.
