ABSTRACT:
A material for medical use in humans and/or animals bearing a biologically active agent, the material being multilayered, as well as a device of this material and a method to produce it. The material includes a core material, where the core material is formed into a body, optionally having the shape of a finished device; two or more layers of coating material of which the first layer has been applied onto the core material and additional layers have been applied onto the coating material of a preceding layer; and where at least one of the layers includes the biologically active agent. A feature of this invention is that the coating material is a biopolymer, a sol-gel produced silica gel or a biologically active molecule.
