FIELD: medicine.
SUBSTANCE: present invention relates to a device for medical implants. Said device comprises a partially cross-linked polyurethane polymer. Partially cross-linked polyurethane polymer contains a soft segment obtained from reaction of methylenediphenyl diisocyanate (MDI) and hydrogenated polybutadiene diol, functionality of which is approximately 1.9 to 2.2 and number average molecular weight is approximately 1000 to 3000. Said polymer also includes a chain extender and additionally contains a crosslinking agent. Chain extender used is diamines, alkanolamines, 1,4-butanediol, ethanediol and hexanediol. Polymer also has a region of linear elastic deformations in range of 5 to 100 %.
EFFECT: present invention enables use of chemically and mechanically resistant partially cross-linked polyurethane polymers in devices of medical implants.
