FIELD: medicine.
SUBSTANCE: invention concerns medicine, particularly neurosurgery. What is disclosed is a biocompatible, biostatic, non-toxic, translucent, however imaginable, elastic, strong, reliably fastened duraplasty graft made of a spatially cross-linked polymer prepared by photopolymerisation of methacrylic oligomers. A graft represents an elastic translucent double-layer film with one layers being relieved, while the other one is smooth. The relief is blue-coloured. Such colour provides intraoperative imaging of the graft for a surgeon. At the same time, the unit dimensions of the relief drawing are such that the graft is translucent enough to control the hemostasis efficiency. The layer adjoining the brain is smooth. A roughness degree of the smooth layer ranges within 10 to 20 nanometers to eliminate the adjoining tissue ingrowth into the graft and its opacity on service.
EFFECT: improved graft performance.
