The invention provides an artificial blood vessel stent and a preparation method and application thereof. The artificial blood vessel stent includes: a matrix, which is a cylindrical body with a cavity formed by a cavity wall, and the cavity wall includes a staggered structure formed by overlapping fiber filaments; a hydrogel layer, which is formed on the outer surface of the cavity wall; and the endothelial cell layer, which is present on the inner surface of the cavity wall; wherein the outer surface of the cavity wall is the surface away from the cavity, the cavity wall is The inner surface is the surface that forms the cavity. The artificial blood vessel stent of the invention has a high degree of endothelialization, uniform distribution, good mechanical properties, and is beneficial to the adhesion and growth of cells. Further, in the preparation method of the artificial blood vessel stent of the present invention, the raw materials are easy to obtain, and the preparation method is simple and feasible, and can be mass-produced. |
