ABSTRACT:
In a method of manufacturing a double-layer membrane of different polymers or polymer mixtures with opposite blood-compatible and tissue-compatible surfaces, a first polymer solution of a blood-compatible polymer and a second solution of a tissue-compatible polymer are extruded concurrently in layered form through a nozzle into a coagulation bath so as to form a double layer membrane.
