摘要 |
The invention relates to three-layer vascular prostheses comprising an internal layer 1, a middle layer 2 and an external layer 3 which is characterized in that the middle layer 2 is made from a physiologically non-resorbable, porous material, and the internal layer 1 and the external layer 3 are self-supporting and are made from a physiologically resorbable, fibrillar material, and are tanned. The internal layer 1 and the external layer 3 preferably consist of collagen, but have different resorbability. The middle layer 2 is preferably made from inert fibres, preferably synthetic fibres, by means of textile technology. The biologically resorbable layers preferably comprise chemically or physically bonded or incorporated pharmacologically active substances. <IMAGE> |
