Silk is a non-absorbable braided surgical suture composed of an organic protein called fibroin. The protein is derived from the domesticated species Bombyx mori (B mori) of the family Bombycidae.


  • Smooth passage through tissue while
  • Good knot security

Silk suture is indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic, and neurological procedures.

Silk suture elicits a minimal acute inflammatory reaction in tissue, which is followed by gradual encapsulation of the suture by fibrous connective tissue.

Tensile Strength
Silk suture is non-absorbable suture, however gradual loss of the suture tensile strength may occur over time with progressive degradation of the proteinaceous silk fiber.

Ethylene oxide.

Silk suture is non-absorbable available undyed (white) or dyed black (logwood extract) with either braided or twisted design and a silicone coating (unless otherwise noted), The suture is supplied sterile in precut lengths attached to various needle types in one-dozen boxes, or non-needled.
