| 内容： | A method of making a drug eluting stent comprises forming a porous stent body surface layer by ion implantation, applying a layer of ceramic particles on the porous layer and compressing the layer of ceramic particles. The layer of ceramic particles can be compressed to successively higher densities. Drugs can be loaded into the layer of ceramic materials at a relatively low density before the layer of ceramic materials is compressed to a higher density to achieve a desired low drug release rate. |
