MEDICAL PRODUCTS AND METHOD FOR MAKING THEM Russian patent published in 2013 - IPC A61L27/04 A61L27/06 A61L27/30 A61L31/08 A61L31/16 A61F2/28 

FIELD: medicine.

SUBSTANCE: invention refers to medical products, and to a method for making medical products. A carrier material is treated by electrolytic oxidation for pulse current feed at frequency of 50 to 10000 Hz onto the carrier material in an acidic bath or an alkaline bath to form a film having micropores and/or microroughnesses of the density of 5×10⁴/mm² or more on the surface of the carrier material, and then the carrier material is treated by iodine impregnation for impregnating the film with iodine or iodine compounds. The iodine compound preferentially represents iodine polyvinyl pyrrolidone, iodine β-cyclodextrine or silver iodide. The carrier material represents a material of Ti or a Ti alloy, stainless steel or a Co-Cr alloy. The film may be formed by using any of the chemical treatment, thermal treatment and mechanical treatment, or a combination of these treatments instead of electrolytic oxidation.

EFFECT: saving costs for preparing medical products with high microbial activity and long-time antimicrobial activity, and biological compatibility.
