Dear Armine Badalyan:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

The Golnit Nylon Monofilament Suture is a synthetic monofilament nonabsorbable sterile surgical suture composed of the long-chain aliphatic polymers Nylon 6,6. The suture is pigmented black (logwood extract) or blue (FD&C Blue No. 2) to enhance visibility or is also available undyed (clear).

The suture has been designed to meet the requirements of the United States Pharmacopeia (USP) related to diameter, needle attachment and tensile strength. The suture is supplied sterile and is provided according to customer specifications. The device is available in pre-cut lengths from 10 cm

{4}------------------------------------------------

to 300 cm in 5 cm intervals and in USP sizes 10-0 through 2. It can be attached to a stainless-steel needle or be without a needle. Needles are available with various tip shapes (taper, cutting, reversecutting, taper-cutting, spatula, and diamond), curvatures (1/2, 3/8, 5/8, 1/4 or straight) and lengths (4 mm to 70 mm).

Each suture is packaged into a labelled two-pouch packaging system consisting of medical grade heat-sealable pouches. The suture is sterilized by ethylene oxide and is intended for single use only.

# V. INTENDED USE / INDICATIONS FOR USE

The Golnit Nylon Monofilament Suture is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular or neurological procedures.

The Golnit Non-Absorbable PTFE Surgical Suture was used as a reference device to support equivalence of the needle component and to support adoption into the product family for sterilization. Both the reference device and proposed device use the same stainless-steel needle from the same supplier and have the same sterilization parameters. The proposed device may be supplied with additional needle tip shapes.

## VII. PERFORMANCE DATA

No clinical or animal testing was conducted.

Testing that was performed demonstrate that the suture meets the requirements outlined in Class II Special Controls Guidance: Surgical Sutures; Guidance for Industry and FDA; June 3, 2003. Testing in accordance with to the USP monographs for non-absorbable sutures, including an evaluation of diameter, tensile strength, and needle attachment strength, was performed. This performance testing demonstrated that the Golnit Monofilament Suture meets the USP requirements for suture diameter, suture needle attachment, and tensile strength.

Real-time aging stability testing was performed to support shelf life of the Golnit Nylon Monofilament Suture, and this testing supported the shelf life of the device.

Biocompatibility testing was also performed per Use of International Standard ISO 10993-1, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process", Guidance for Industry and Food and Drug Administration Staff. This testing demonstrated that the device is biocompatible.

All testing demonstrated that the Golnit Nylon Monofilament Suture is as safe and effective as the predicate device.

## VIII.CONCLUSIONS

Based on the performance data and comparison to the predicate device, the Golnit Nylon Monofilament Suture has been shown to be substantially equivalent to the legally marketed predicate device.
