Zusammenfassung:A novel prosthesis for use in repairing or replacing soft tissue is disclosed, which comprises a triaxially-braided fabric element having interwoven first, second and third sets of fibers, with the fibers of the second and third sets being oriented at substantially the same acute braiding angle with respect to the fibers of the first set. An elongated ligament prosthesis exhibiting the desired properties of high strength and high elasticity may be prepared by selecting high elasticity fibers for the first set, orienting said first set of fibers in the longitudinal direction of the prosthesis and selecting fibers having high yield strength and high Young's modulus for the second and third sets. A tubular prosthesis in which high elasticity fibers are oriented in the longitudinal direction is highly suitable for use as a vascular prosthesis. A prosthesis of the invention may also be manufactured in the form of a prosthetic heart valve leaflet.
