Bio-compatible polymeric materials

摘要: A method of making a medical device or part thereof includes step forming porous layer on the outside support material, wherein is, in preferred embodiments, selected from polyetherketone and polyetheretherketone. The may be prepared which treating region material to render it such treatment involve diffusing supercritical fluid into polymer using solvent dissolve at surface, followed by subsequent precipitation surface. Alternatively, is arranged applied foam. In further alternative, rendered after has been contacted with for example virtue comprising removable salt. Medical devices methods are also described.
