The invention relates to the field of medical devices, in particular to a new absorbable developable magnesium alloy vascular stent for the treatment of endovascular stenosis. The magnesium alloy stent has all-round, multi-angle imaging under X-ray structural design, and realize the development by means of polymer bonded between tag and magnesium alloy stent assembly, imaging markers by polymer binder to obligate enhancement ring assembly, to avoid galvanic corrosion occurred between developing material and magnesium alloy matrix, And the visibility of degradable magnesium alloy stent in X-ray developing equipment was realized. The invention effectively reduce the enhancement of the tag to add to support grip size (profile) the effects of system pressure, avoid the enhancement material and magnesium alloy stent strut caused by galvanic corrosion occurred between the support arm fracture, which can lead to sustained loss of lesion vessels effectively, accurate positioning bracket position, improve the maneuverability of the stent, there are no blind spots.
