MEDICAL INSTRUMENT, MEDICAL MATERIAL AND METHOD FOR MAKING MEDICAL INSTRUMENT AND MEDICAL MATERIAL Russian patent published in 2012 - IPC A61L31/04 C08K5/29 C08L67/00 C08L101/16 

FIELD: medicine.

SUBSTANCE: medical material is processed by ionising radiation at radiation dose 5 to 100 kGy and contains a biodegradable resin and a polycarbodiimide compound in the amount of 0.1 to 10 wt % of resin. Biodegradable resin contains at least one resin specified in a group consisting of polybutylene succinate, and a polybutylene succinate copolymer, and polylactic acid or poly(3-hydroxyalkanoate) in the amount of 0 to 50 wt % of said polybutylene succinate resin. Group of inventions refers to a sterilised medical instrument made of said material, and to methods for making the medical material and the medical instrument which involve formation of said material and its processing by ionising radiation at radiation dose 5 to 100 kGy.

EFFECT: improved thermal stability, reduced tensile elongation and maintained strength and impact resistance after ionising radiation in the made medical material and instrument.
