VERFAHREN ZUR HERSTELLUNG VON KUENSTLICHEN BLUTGEFAESSPROTHESEN UND KUENSTLICHE BLUTGEFAESSPROTHESE

摘要

A blood vessel prosthesis and a method of producing such a prosthesis in which single fibers having a sticky surface are sprayed onto a rod to form a tube from which the rod is subsequently removed, the fibers being formed in at least one layer, the fibers being applied to the rod in one or more selected directions and, in one form, the fibers, when stuck together, form a tube into which connective tissue cannot grow, the prosthesis having properties such as radial elastic expansibility, non-kinking and the like adaptable to those of natural arteries and views the tube may also be provided with an inner layer of flexible foil for impermeability or an outer coating to provide a smooth outer surface.
