Interventional stents are emerging medical apparatus and instruments which can be implanted into the lesion location to reopen and scaffold the blocked cavities. The ideal stents must have reliable mechanical properties, and the current research methods on mechanical properties of the stents are mainly based on theoretical analysis, numerical analysis and experimental test. In this article, all kinds of analytic methods on testing mechanical properties of the stents and their limitations are discussed and summarized in detail, and further research on the stents is prospected as well.
