DemeTECH Silk Nonabsorbable Suture is a nonabsorbable, sterile, surgical suture composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx mori (B. mori) of the family Bombycidae. The braided sutures with or without attached needles,. The product is available in several suture lengths and attached needle types. DemeTECH Silk Nonabsorbable Suture meets all requirements established by the United States Pharmacopeia for Nonabsorbable Surgical Sutures.
The DemeTECH Nonabsorbable Silk Suture with and without needles is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures. Product is intended for long term use over 30 days.
DemeTech’s Silk suture is a non-absorbable, sterile, surgical suture composed of an organic protein called fibroin. DemeTech’s silk sutures are processed to remove the natural waxes and gums from its origin. . As Silk is a natural fiber, it 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 DemeTech’s 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 fora tighter, more compact braid. - DemeTech’s Silk suture is dyed black for easier visibility in tissue. - DemeTech’s Silk suture is non-absorbable and multifilament in nature. - Although DemeTech classifies its silk suture as a non-absorbable suture, it loses most of its tensile strength in one year
