MEDICAL POLYOLEFIN DEVICE Russian patent published in 2015 - IPC A61L29/04 A61L29/08 A61M25/16 

FIELD: medicine.

SUBSTANCE: group of inventions relates to the field of medicine and can be used for obtaining medical products from polymers. The method of obtaining an element of a medical product includes provision of a preliminarily manufactured product, provision of a coating composition, application of the coating on the preliminarily manufactured product in order to obtain the element of the medical device, selected from tubes and catheters, which has on it a layer of the said coating composition, and irradiation of the coating composition by UV or visible region light for covalent cross-linking of the coating composition. The coating composition contains one or several hydrophilic polymers as a polymer component and low-molecular weight skeletons, which include photoinitiator components in an amount of 0.01-20 wt %, and the preliminarily manufactured product contains a polymer, selected from a copolymer of ethylene - (meth)acrylic acid; thermal polymer of ethylene - (meth)acrylic acid - acrylic acid ester and ionomer of ethylene - (meth)acrylic acid. The group of inventions also relates to medical devices, containing the elements, selected from tubes and catheters, obtained by the said method.

EFFECT: group of inventions provides obtaining the elements of the medical products, possessing the property of counteraction to twisting, good damping properties and balanced rigidity-elasticity.
