DEVELOPMENT OF TISSUE ENGINEERED SMALL DIAMETER VASCULAR GRAFT FOR THE CARDIOVASCULAR SURGERY NEEDS

Abstract

RICICD has large experience in the development of products for cardiovascular surgery, in particular, the bioprosthesis heart valves and blood vessels. Since 2010, under the leadership of the academician of RAS L. S. Barbarash researches to create bioresorbable vascular prostheses of small diameter began. The primary purpose – to create polymer structures with bio-directed action capable to replace individual structures of a living organism, in particular, of cardiovascular system. Scientific novelty of the problem lies in using a new approach for creation an organ directly in the patient’s body by biofunctional and bioresorbable features of polymer structures. The long-term patency of PCL vascular grafts and PHBV and PCL composition grafts had proved. The in vitro experiments had proved that growth factors incorporated into composition of biodegradable grafts retain their biological activity. The long-term in vivo experiments had demonstrated that vascular endothelial growth factor had accelerated endothelization and had improved vascular patency of biodegradable polymer grafts.
