A multi-layer magnesium alloy cardiovascular stent, comprising a magnesium alloy stent body; the stent wall of the magnesium alloy stent comprises two or more layers of magnesium or magnesium alloy (1); each layer of the stent wall has a thickness of 0.15 mm-0.3 mm, thus effectively avoiding the fracture or collapse of the magnesium alloy caused by corrosion and blood flowing, and preventing the magnesium alloy from losing support before blood vessel shaping. |
