FIELD: medical engineering. ^ SUBSTANCE: implant is produced as composition of biocompatible polymer (68-82) and permanent magnetic powder material (18-32) in % by volume. Polymers selected from a group comprising polyacrylates, vinyl polymers, polyorganosiloxanes, collagen copolymer or silicon rubber are usable as the biocompatible polymer. Magnetic powder material like samarium-cobalt system or neodymium-iron-boron system is usable as the permanent magnetic powder material. Polyacrylate is selected as either polymethylacrylate or polymethylmetacrylate or poly-2-hydroxyethylmetacrylate or polyacrylic acid. The vinyl polymer is taken as polyvinyl chloride or polyvinyl fluoride or polyvinyl pyrrolidone or polyvinyl acetate. The collagen copolymer is selected from collagen copolymer with either acryl or vinyl row monomer. The organosiloxane is either polydimethylsiloxane rubber or polymethylvinylsiloxane rubber. The implant has permanent magnetic powder material with particle size varying from 0.5 to 60 mcm. Implant surface has an additional layer produced from hydrogel like one having hydroxyethylmetacrylate with acrylamide and dimethyl acrylate of tridecoethylene glycole as substrate. ^ EFFECT: retained given shape and thickness. ^ 7 cl, 1 tbl |
