Intended Use

Indicated for use as non-absorbable sutures in general soft tissue approximation and/or ligation, including use in Cardiovascular, Ophthalmic and Neural tissue. Surgilon (polyamide), Dermalon, Ophthalon are both braided and monofilament sutures available in white or dyed (black or blue) with a Logwood extract. These sutures are available in various lengths, diameters and quantities with or without surgical needles. These sutures are not absorbed, progressive hydrolysis of the nylon in-vivo may result in gradual loss of its tensile strength.

Device Story

Non-absorbable surgical sutures composed of long-chain aliphatic polymers (Nylon 6 or 6,6); available as braided or monofilament strands; white or dyed black/blue with Logwood extract; supplied with or without needles. Used by surgeons in OR/clinical settings for soft tissue approximation and ligation. Device features automated needle end stiffening via medical-grade adhesive application, curing, and cutting. Sutures provide mechanical tissue support; not absorbed by body, though gradual tensile strength loss occurs via in-vivo hydrolysis. Benefits include secure tissue closure in cardiovascular, ophthalmic, and neural applications.

Clinical Evidence

Bench testing only. Biocompatibility testing performed in accordance with ANSI/AAMI 10993. Sutures meet all requirements established by the United States Pharmacopeia (USP) and European Pharmacopoeia (EP) for surgical sutures.

Technological Characteristics

Materials: Nylon 6 or Nylon 6,6 (long-chain aliphatic polymer). Coating: Silicone. Dye: Logwood extract. Form factor: Braided or monofilament strands of various lengths/diameters, with/without needles. Manufacturing: Automated needle end stiffening using medical-grade adhesive. Sterilization: Not specified. Standards: ANSI/AAMI 10993, USP, EP.

Indications for Use

Indicated for general soft tissue approximation and/or ligation, including cardiovascular, ophthalmic, and neural tissue procedures. Prescription use only.

Regulatory Classification

Identification

Nonabsorbable polyamide surgical suture is a nonabsorbable, sterile, flexible thread prepared from long-chain aliphatic polymers Nylon 6 and Nylon 6,6 and is indicated for use in soft tissue approximation. The polyamide surgical suture meets United States Pharmacopeia (U.S.P.) requirements as described in the U.S.P. monograph for nonabsorbable surgical sutures; it may be monofilament or multifilament in form; it may be provided uncoated or coated; and it may be undyed or dyed with an appropriate FDA listed color additive. Also, the suture may be provided with or without a standard needle attached.

Special Controls

*Classification.* Class II (special controls). The special control for this device is FDA's “Class II Special Controls Guidance Document: Surgical Sutures; Guidance for Industry and FDA.” See § 878.1(e) for the availability of this guidance document.

July 7, 1998 Date of Summary:

Surgilon (polyamide) Ophthalon and Dermalon Non-Absorbable Surgical Suture are braided and monafilanent suturs with a silicone coated dyed white or black with Logwood extract. These surgical sutures are composed of a long-chain aliphatic polymer Nylon 6 or Nylon 6,6. Surgilon, Dermalon and Ophthalan sutures are a class II device per 21 CFR Section 878.5020. Classification Code: 80GAR.

Sugilon (polyamide), Opthhalon, and Dermalon sutures are indicated for use as nonabsorbable sutures in general soft tissue approximation and/or ligation, including use in Cardiovascular, Ophthalmic and Neural tissue. These sutures are braided and monofilament sutures available in various lengths, diameters and quantities with or without surgical needles. They are not absorbed, progressive hydrolysis of the nylon in-vivo may result in gradual loss of tensile strength over time.

Similarities between the proposed Surgilon, Ophthalon, and Demalon sutures to currently marketed sutures are 1)all are composed of long-chain aliphatic polymer, 2)all are sterile sutures, 3)all share the same indications for use, 4) all are available in the same lengths, diameters, quantities, colors and sizes, 5) all are available with and without surgical needles and 6)all are packaged in identical Tyvek/Mylar packaging.

The only difference between the proposed vs. The predicate sutures are an automated vs. a manual needle end stiffening process. TheSugilyn, Ophthalon and Demalon Absorbable Surgical Sutures, will be manufactured using an automated end stiffening process of applying the medical grade adhesive to a portion of the nylon strand which is then cured and cut to length. The predicate nylon suture is currently manufactured using a manual end stiffening process of winding the nylon suture material onto racks and dipping the end in a nylon resin bath, curing then cutting the suture to length.

#### Summary of Safety and Effectiveness

C:\temp\S 10ksuro.doc

{1}------------------------------------------------

These representative Surgical Sutures, with adhesive, were tested for biocompatibility in accordance to ANSI/AAMI 10993. Biological Evaluation of Medical Devices Part-1: Evaluation and Testing. Further, surgical sutures meet all requirements established by the United States Pharmacopeia (SP) and European Pharmacopoeia (EP) for surgical sutures.

Sherewood-Davis & Geck considers the proposed Surgilon, Ophthalon ,and Dermalon Surgical Sutures (w/adhesive) to be substantially equivalent in design, composition and intended use, to the currently marketed Surgilon, Dermalon, Ophthalon non-absorbable sutures covered under K930586.

Dear Ms. Johnson:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices that were regulated as transitional devices and that have been reclassified into class II. Notice of this reclassification was published in the Federal Register on Friday, May 31, 1991 (Vol. 56, No. 105, Pages 24684 and 24685). A copy of this Federal Register can be obtained by calling the Division of Small Manufacturers Assistance (DSMA) at [phone] or [phone]. You may, therefore, market the device, subject to the general controls provisions of the Federal Food, Drug, and Cosmetic Act (Act) and the following limitations: .
