Polyamide suture is nonabsorbable sterile surgical suture composed of the long chain aliphatic polymers Nylon 6 Nylon 6,6. The suture is provided dyed (black or blue), or undyed (clear). The pigment for the black dyed suture is Hematein (Logwood) black, the pigment for the blue dyed is FD&C #2 blue. The suture is packaged both dry or in a wetting solution of 90% Isopropyl Alcohol, 0.5% Diethylethanolamine, 0.5% Sodium Benzoate (U.S.P Grade) and Water Q.S. AD 100%. The product meets all requirements established by the United States Pharmacopeia (U.S.P.) for nonabsorbable surgical sutures.

Polyamide Suture is indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic and neurological procedures.

Polyamide Suture elicits a minimal acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissue. While Polyamide is not absorbed, progressive hydrolysis of the nylon in vivo may result in gradual loss of its tensile strength over time.
