Silk (SK) — Non-Absorbable Natural Braided Surgical Suture
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 are available 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.
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. This product is not approved in Europe to be used on the heart or with the central circulatory and central nervous system.
More DetailsUnderstanding how DemeSILK™ Silk behaves once placed in the body
The DemeTECH Silk Nonabsorbable Suture elicits an acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissue — typically occurring within 14–21 days. While DemeTECH Silk Nonabsorbable Suture is not absorbed, progressive degradation of the proteinaceous silk fiber in vivo may result in gradual loss of all of the suture's tensile strength within one year.
The suture is supplied sterile in pre-cut lengths both with and without affixed needles of various straight and curved needle types, in cartons of one dozen.
Elicits an acute inflammatory reaction in tissues, characteristic of a natural fiber foreign body response, followed by gradual encapsulation by fibrous connective tissue within 14–21 days.
While not absorbed, progressive degradation of the proteinaceous silk fiber in vivo results in gradual loss of all tensile strength, typically within the first year post-implantation.
Following the initial inflammatory response, the suture undergoes gradual encapsulation by fibrous connective tissue, providing long-term structural integration at the wound site.
DemeTech's Rapid Absorbable sutures combine the benefits of synthetic and natural sutures for superior performance
DemeTech's Silk suture is a non-absorbable, sterile, surgical suture composed of an organic protein called fibroin. Processed to remove the natural waxes and gums from its silkworm cocoon origin, allowing for a tighter, more compact braid. As a natural fiber, silk elicits an acute inflammatory reaction, followed by gradual encapsulation of the suture by fibrous connective tissue — typically occurring within 14–21 days. While classified as non-absorbable, progressive degradation of its proteinaceous fibers results in gradual loss of most tensile strength within the first year.
Raw silk from the silkworm larva's cocoon is processed to remove its natural waxes and gums prior to braiding — allowing for a tighter, more compact, and more uniform braid structure.
DemeSILK is dyed black for easier identification and visibility in tissue, aiding the surgeon in precise suture placement and knot inspection throughout the procedure.
DemeSILK is non-absorbable and multifilament in nature, offering surgeons the familiar handling characteristics, pliability, and ease of knot tying associated with braided natural sutures.
Although classified as non-absorbable, DemeSILK loses most of its tensile strength within one year due to progressive degradation of its proteinaceous silk fibers in the physiological environment.
As a natural fiber foreign body, silk elicits an acute inflammatory reaction in tissues. Gradual encapsulation by fibrous connective tissue follows, typically completing within 14–21 days post-implantation.
DemeSILK meets all requirements established by the United States Pharmacopeia for Nonabsorbable Surgical Sutures, ensuring consistent quality and safety standards across all available sizes.
