HISIL Silk suture is a non-absorbable, sterile, surgical suture composed of an organic protein called fibroin. Silk Surgical Suture is coated with specially developed silicon for extra smooth surface like monofilament, which allows easy passage through the tissue and non capillary action. While HISIL silk sutures are not considered absorbable sutures, progressive degradation of its fibers results in the gradual loss of tensile strength within the first year.


  • 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.
  • HISIL Silk suture is dyed black for easier visibility in tissue.
  • HISIL Silk suture is non-absorbable and multifilament in nature.
  • Although HLL classifies its silk suture as a non-absorbable suture, it loses most of its tensile strength in one year, and is completely absorbed in 2 years. Thus, HISIL Silk behaves like a very slow absorbing suture.
  • HLL coats its Silk in silicon to limit absorption, increase ductility, and minimize tissue reactivity.
  • The very flexible suture with a special wax coating ensures excellent handling
  • A modern surface coating treatment provides the suture with an outstanding smoothness
  • Minimal variations of diameter along the thread
