Abstract
Composite grafts are provided that have a porous wall structure to permit ingrowth thereinto under in vivo conditions but which include a generally non-porous membrane in the wall to prevent substantial fluid passage therethrough so as to provide an implantable porous graft that does not require preclotting prior to implantation. One or more of such membranes are formed in place by applying a polymeric membrane-forming composition during the formation of a graft body by winding elongated extruded fibers on a mandrel.
