Beschreibung
Zusammenfassung:	The invention relates to a medical product for interventional therapy, in particular to a novel intravascular coated stent which comprises a stent body and a coat. The coat comprises a polymer bottom layer formed by coating on the surface of the stent body and multilayer silk peptide layers and chitosan layers which are formed by coating on the surface of the polymer bottom layer, wherein the silk peptide layers and the chitosan layers are arranged alternately. A stent coat is prepared by a method of layer upon layer electrostatic self-assembly, has better compatibility with blood, and can reduce late restenosis rate of stent post-operative heart.
