Monosof™ and Dermalon™ monofilament and Surgilon™ braided nylon sutures are use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic, and neurological surgery. Monosof™ and Dermalon™ monofilament and Surgilon™ braided sutures are inert, nonabsorbable, sterile sutures composed of the long-chain aliphatic polymers Nylon 6 and Nylon 6.6. The braided sutures are coated uniformly with silicone to enhance handling characteristics, ease of passage through tissue and reduction of capillarity. Monosof™ monofilament sutures are nonabsorbable nylon surgical sutures which are available either dyed black, with Logwood extract, or undyed (clear). Dermalon™ monofilament sutures are nonabsorbable nylon surgical sutures and are available dyed blue. Surgilon™ braided sutures are also nonabsorbable nylon surgical sutures available dyed black or undyed (white). Monosof™ and Dermalon™ monofilament and Surgilon™ braided nylon sutures meet all requirements established by the United States Pharmacopeia (USP) and the European Pharmacopeia (EP) except for minor variations in suture diameter for Monosof™ sizes 0, 3-0, 4-0, 5-0, 6-0 and 7-0.
