CRUSHED POLYMERIC HYDROGELS FOR PREVENTION OF COMMISSURE FORMATION AND METHODS FOR THEIR PREPARING Russian patent published in 2003 - IPC

FIELD: medicine, pharmacy, polymers. SUBSTANCE: invention relates to molecular cross-linked gels comprising various biological and nonbiological polymers, for example, proteins, polysaccharides and synthetic polymers. Such gels can be applied on needed sites in patient body by extrusion gel through a hole on the target site. Gels can be destroyed mechanically and to use them for implantation, for examples, in articles, such as breast prostheses. Usage of such gels in living body (in vivo) is useful for prophylaxis of formation of postoperative spinal and other tissue commissures, for filling tissue defects, by tissue, body cavities, surgery defects and so on. EFFECT: improved preparing methods, valuable medicinal properties of hydrogels. 44 cl, 5 dwg, 4 tbl
