METHOD FOR MAKING BIORESORBED SMALL-DIAMETER HYBRID VASCULAR GRAFT

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine and tissue engineering, and may be used in cardiovascular surgery for small-vessel bypasses. A vascular graft is made by two-phase electrospinning with the staged introduction of the ingredients into the polymer composition.;EFFECT: making the bioresorbed small-diameter vascular graft possessing the improved biocompatibility ensured by using the polymer composition of polyhydroxybutyrate (PHBV) with oxyvalerate, and epsilon-polycaprolactone with type IV collagen, human fibronectin and human fibroblast growth factor (hFGF) additionally introduced into the composition.;2 cl, 1 ex
