ADVASYL
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, gives ADVASYL:
-
Excellent handling characteristics
-
Smoother surface for minimal tissue drag & trauma
-
Excellent and consistent knotting strength

ADVASYL is a non-absorbable sterile surgical suture composed of an organic protein called fibroin. This protein is derived from Bombyx Mori L. (species of the family Bombycidae). Braided silk is coated with wax and is available dyed in logwood black
ADVASYL suture is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic and neurological procedures.
Due to the gradual loss of tensile strength which may occur over prolonged period In-vivo, ADVASYL suture should not be used where permanent retention of tensile strength is required. ADVASYL suture is contraindicated in patients with known sensitivities or allergies to Silk.
ADVASYL suture elicits a minimal initial inflammatory reaction in tissues which is followed by gradual encapsulation of the suture by fibrous connective tissue. While silk is not absorbed, progressive degradation of the proteinaceous silk fibre, In-vivo may result in gradual loss of all the suture's tensile strength overtime.
*Mass Absorption: Time in days required for suture to be totally absorbed in the body.
