Abstract
Abstract A flexible, isoelastic polymer surgical suture and suture construct formed from a material selected from the group consisting of silicone, polyurethane, polyurethane copolymers, rubber, and other hemocompatible and biocompatible thermoplastic elastomers, wherein the suture and suture construct is formed from a single or multiple filament, the suture and suture construct having an elastic modulus between about 50 to 2000 psi, a tensile strength between about 500 to 50,000 psi, and a tensile elongation between about 100 to 1000 percent. In an alternate suture construct, the construct includes a base material and an inner core formed from a higher-strength fiber or group of fibers having a helical orientation. The low-modulus base material is selected from the group consisting of silicone, polyurethane, polyurethane copolymers, rubber, and other hemocompatible and biocompatible thermoplastic elastomers. In an alternate suture construct, the construct includes a base material and an inner core formed from a higher-strength fiber or group of fibers having a helical orientation. The inner core has an elastic modulus above about 2,000 psi, a tensile strength above about 10,000 psi, and a tensile elongation between about 1 to 80 percent.
