IMPROVED BIORESORBABLE SEALANTS FOR POROUS VASCULAR GRAFTS

摘要

A bioresorbable sealant composition useful for impregnating implantable soft-tissue prostheses includes at least two polysaccharides in combination to form a hydrogel or sol-gel. The sealant compositions may optionally include a bioactive agent and/or be cross-linked subsequent to application of these compositions to the substrate surface.
