Surgical Implant |
摘要 |
A surgical implant comprising: a substrate having an exterior surface and a plurality of layers disposed over the substrate exterior surface. The substrate comprises a polymeric material, and the plurality of layers comprises: an activated substrate surface layer; a valve metal layer; and a porous valve metal oxide layer, wherein the valve metal layer is disposed between the activated substrate layer and the porous valve metal oxide layer. The disclosure provides for a method for producing a polymeric surgical implant. The exterior substrate surface is treated by one or more processes comprising: plasma activation; electron beam irradiation; ultraviolet light; and low energy Ar+ ion beam irradiation; producing an activated substrate surface layer. A plurality of layers is applied over the activated substrate surface layer. The surface is converted by a spark-anodization process in an alkaline bath containing Ca and P ions into a layer of porous valve metal oxide. |
