Sofsilk™ Silk Sutures

Sofsilk™ Silk Sutures are non-absorbable, 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 and braided to produce Sofsilk™ surgical silk sutures. 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.

Sofsilk™ sutures meet all requirements established by the United States Pharmacopeia (USP) and the European Pharmacopeia (EP) for non-absorbable surgical sutures, except for size 8-0, which DIFFERS FROM U.S.P. MAXIMUM DIAMETER REQUIREMENTS BY UP TO 0.005 mm.


  • Smooth, mutiple pass rundown, minimizes breakage
  • Wax Coating
  • Available white or colored black with Logwood extract.


Sofsilk™ sutures are for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic, microsurgery, and neurological surgery.
