Silk sutures are nonabsorbable sterile non-mutagenic surgical sutures composed of natural proteinaceous silk fibers called fibroin. This protein is derived from the domesticated silkworm species Bombyx mori of the family bombycidae. The silk fibers are treated to remove the naturally-occurring sericin gum. The proprietary coating process provides smooth flow through tissue while maintaining optimal knot security. Sutures are indicated for use in general soft tissue approximation and/or ligation including use in cardiovascular ophthalmic and neurological surgery.
