The present invention relates to a coated stent. The coated stent comprises the following parts: a radially compressible inner layer stent and an outer layer stent sleeving the inner layer stent. Theradially compressible inner layer comprises an inner layer support skeleton and an inner layer coating disposed on the inner layer support skeleton; the outer layer stent covers at least a portion ofthe inner layer stent, and includes an outer layer support skeleton and an outer layer coating disposed on the outer layer support skeleton; and one end of the outer layer coating is sealingly connected to the inner layer coating, the tensile strength of the outer layer coating is greater than the tensile strength of the inner layer coating, and the elongation of the outer layer coating is less than the elongation of the inner layer coating. The above-mentioned coated stent can avoid fracture of the outer coating during loading or release, and reduce the risk of failure of the coated stent; and the inner coating can also conform to the curved blood vessel morphology.
