Abstract:
A body compatible endroprosthesis, including:a tubular body including a tubular structural mesh layer;the tubular body further including a graft layer formed of a graft material and having a graft layer surface that forms an inside surface of the tubular body and defines a fluid passage in the tubular body, said graft layer having a first average permeability within a range from about 50 cc/cm.sup.2 /min. to about 5,000 cc/cm.sup.2 /min. at 120 mm Hg and being biocompatible with a first fluid contained in the fluid passage; andthe tubular body further including a membrane layer formed of a membrane material, substantially surrounding the graft layer, and having a second average permeability less than the first average permeability.
