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, 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 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. DemeTech's silk sutures are indicated for use in general soft tissue approximation and/or ligation.

Features include:

• Silk is dyed black for easier visibility in tissue
• Non-absorbable and multifilament in nature
• Although DemeTECH 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, DemeTECH's Silk behaves like a very slow absorbing suture
• Silk is coated in silicon to limit absorption, increase ductility, and minimize tissue reactivity
• DemeTECH's Silk sutures meet or exceed USP minimums
