the invention involves the use of absorbable or absorbable / nonabsorbable components to fabricate textile vascular grafts of all sizes and specifically for repair of the peripheral vascular system and for coronary bypass use . the bioabsorbable component of the graft fosters increased tissue ingrowth into the graft as compared to conventional 100 % nonabsorbable grafts . increased tissue ingrowth leads to greater patency through formation of a vascularized neointima and less tendency to be aneurysmal through formation of a suitable adventitia . the absorbable component can be a variety of materials , including pga , maxom ™, etc ., whereas the nonabsorbable component can be new materials , e . g . novafil ®, or more conventional polymers , including polyester , polyamide or polypropylene . the vascular grafts further comprise an external support helically wrapped therearound and permanently attached to the outside surface .
