METHOD FOR PROCESSING SYNTHETIC TEXTILE IMPLANTED BLOOD CONTACT MEDICAL DEVICES Russian patent published in 2012 - IPC A61L27/34 A61L27/54 A61L33/10 A61F2/06

Abstract RU 2462273 C1

FIELD: medicine.

SUBSTANCE: invention refers to medicine, specifically to cardiovascular surgery and may be used for modification of synthetic implanted medical devices. What is described is a method for processing synthetic textile implanted medical devices involving coating the devices with hydrogel of natural biodegradable polymers wherein the natural biodegradable polymer is presented by polysaccharide chitosan or its derivatives (carboxymethykated sulphated chitosan) in a combination with polyester-poly-3-hydroxybutyrate. The coating is dried and transferred in the water-soluble state by thermal processing at 100°C.

EFFECT: method for processing synthetic textile implanted blood contact medical devices enables providing the devices with a complex of the required properties: higher thromboresistance and antimicrobial action, zero surgical porosity and prolonged drug release.
