Silk Sutures

Non-Absorbable

Braided , Twisted

Silk suture is a non-absorbable, sterile, surgical suture composed of an organic protein called fibroin. silk sutures are processed to remove the natural waxes and gums from its origin. As Silk is a natural fiber, its does illicit an acute inflammatory reaction, which is followed by gradual encapsulation of the suture by fibrous connective tissue (occurring usually in 14-21 days). While  silk sutures are not considered absorbable sutures, progressive degradation of its fibers results in the gradual loss of tensile strength within the first year. silk sutures are indicated for use in general soft tissue approximation and/or ligation. sutures are available white or colored black with Logwood extract. 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.

Virgin silk is a non-absorbable, twisted suture, made of natural silk filaments. Virgin silk is indicated in ophthalmic surgery in soft tissues

 

Distinctive Characteristics of  Silk Multifilament Sutures:

·  - Excellent handling properties
    - Good knot security

      Raw silk is produced by a silkworm larva's cocoon. These natural waxes and gums are removed prior to the        braiding process, allowing for a tighter, more compact braid.   

·   Silk is dyed black for easier visibility in tissue.

·   Silk is non-absorbable and multifilament in nature.

·  Although classifies its silk as a non-absorbable suture, it loses most of its tensile strength in one year, and is completely absorbed in 2 years. Thus, Silk behaves like a very slow absorbing suture.

·  coats its Silk in silicon to limit absorption, increase ductility, and minimize tissue reactivity.

   Smooth, multiple pass rundown, minimizes breakage

These sutures comply with the requirements of
U.S. Pharmacopoeia (U.S.P.) and The European
Pharmacopoeia

Note: Silk sutures meet or exceed USP minimums
