Silk surgical suture is a nonabsorbable, sterile, surgical suture composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx Mory (B. Mori) of the family Bombycidae. Suture characteristics include; braided wax (refined Paraffin, N.F. or Microcrystalline Wax N.F.) coated black (Hematein dyed) or white (undyed) and twisted uncoated white virgin (undyed), or twisted uncoated white (undyed). Silk surgical suture meets all requirements established by the United States Pharmacopeia (U.S.P.) for nonabsorbable surgical sutures.
Indications
Silk surgical suture is indicated for use in general, soft tissue approximation and/or ligation, including use in cardiovascular and ophthalmic and neurological procedures.
Actions
Silk surgical suture elicits minimal acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissue. While Silk suture is not absorbed, progressive degradation of the proteinaceous silk fiber in vivo may result in gradual loss of the suture's tensile strength over time.
