DemeSILK Sutures (DemeTECH)
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.
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.
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 DemeTECH Silk Nonabsorbable Suture is available in various sizes. The suture is supplied sterile in pre-cut lengths both with and without affixed needles of various straight and curved needle types and supplied in cartons of one dozen.
