Braided Natural Non-Absorbable Suture


ADVASYL Suture is non-absorbable, sterile, surgical suture composed of an organic protein called fibroin, derived from the domesticated species Bombyx mori (B. mori).

The suture is processed to remove the natural waxes and sericin gum, dyed black and coated with a 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 advanced extrusion process of copolymer, the exclusive braiding process and coating system, give ADVASYL:

  • Excellent handling characteristics

  • Smoother surface for minimal tissue drag & trauma

  • Excellent and consistent knotting strength

ADVASYL Suture is indicated for use in general soft tissue approximating and/or ligation, including use in cardiovascular, ophthalmic, and neurological procedures.

ADVASYL Suture elicits an acute inflammatory reaction in tissue, which is followed by a gradual encapsulation of the suture by fibrous connective tissue. While silk is not absorbed, progressive degradation of the proteinaceous silk fiber in vivo may result in gradual loss of all of the suture’s tensile strength overtime.

Due to the gradual loss of tensile strength which may occur over prolonged periods in vivo, silk suture should not be used where permanent retention of tensile strength is required.
