Riverlon™ is a nylon monofilament nonabsorbable, sterile surgical suture composed of the long-chain aliphatic polymers Nylon type 6 or Nylon type 6/6. Monofilament Nylon suture may be either dyed black (logwood), dyed blue (FD&C Blue No.2) or white (undyed). Nylon suture is coated with silicone.

Uniform diameter of the suture
Maximum flexibility of the strand
Excellent and consistent knot security
Minimal memory

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

Riverlon™ suture elicits a minimal acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissue.

As with any nylon suture, though not absorbed, progressive hydrolysis of the suture in vivo may result in gradual loss of tensile strength over time. Nylon suture should not be used where permanent retention of tensile strength is required.

Ethylene oxide.

Packaging -
Nylon nonabsorbable is a monofilament and is clear, dyed black (logwood extract), or blue (FD&C Blue No.20.) It is available in USP sizes 11-0 through 5 (metric sizes 0.1-7). The suture is supplied sterile in precut lengths attached to various needle types in one-dozen boxes, or non-needled on ligating reels.
