Elastomeric monofilament surgical sutures are characterized by the following combination of mechanical properties: Yield elongation from about 2 to 9 percent Visco-elastic elongation - from about 10 to 30 percent Young's modulus from about 30,000 to 200,000 psi Tensile strength at least about 40,000 psi Knot strength - at least about 30,000 psi The sutures are soft and flexible with superior knot tying and knot security properties. The sutures may be prepared from selected elastomeric copolyether/ester polymers which may be melt extruded and drawn to obtain the desired fiber properties.
