The fabric consists of multifilament yarns of a synthetic material. During production, the fabric is subjected to several shrinking operations by compression and crimping, which are intended to give it an anisotropic elastic flexibility close to the mechanical properties of a natural tissue. The yarns comprise curls which are situated in planes parallel to the fabric, and they open out in the interstices so as to make spaces promoting the growth of natural tissues. Application to replacing cardiac valves.
