The invention provides a preparation method of a degradable
drug eluting
stent. The preparation method comprises the following steps: A) heating a degradable macromolecular
polymer pipe to deformation temperature, and then expanding the degradable macromolecular
polymer pipe in the radial direction and / or axial direction of the degradable macromolecular
polymer pipe, so that an expanded pipe is obtained, wherein the wall thickness of the expanded pipe is no less than 80mu m, and the radial
expansion rate of the degradable macromolecular polymer pipe is 400-800%; B)
cutting the expanded pipe, so that a bare
stent is obtained; and C) carrying out surface treatment on the bare
stent, and then
coating with a degradable
drug coating, so that the degradable
drug eluting stent is obtained.
