New carbon based material layers for medical application

Materials based on the linear chain carbon (sp-bonds between atoms) and their applications are described. Such materials were found to be promising biomaterials. The materials are produced by specific chemical and physical processes. Carbion (an improved analogue of carbylan) has a polymeric basis, bearing on its surface a linear-chain carbon layer with long chains, oriented mainly along the surface. Carbion fiber and carbion-coated materials are prepared by chemical modification (via the dehydrohalogenation reaction of the original polymeric substance, namely polyvinylidene halide). The carbion materials and implants mentioned above are fibers knitted with carbion-coated fiber nets and other products (sutures, artificial knitted vascular vessels, urethras, etc.).
