COVIDIEN SUTURE: LS-638

Sofsilk sutures are non-absorbable, sterile, non-mutagenic surgical sutures composed of natural proteinaceous silk fibers called fibroin. The braided sutures are available coated uniformly with either silicone or a special wax mixture to reduce capillarity and to increase surface lubricity, which enhances handling characteristics, ease of passage through tissue and knot run-down properties. The manufacturing process, from braiding to coating, gives the suture superior softness and compliance for maximum surgical handling. The proprietary coating process provides smooth flow through tissue while maintaining optimal knot security. Sofsilk sutures are for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic, microsurgery and neurological surgery.
