PREDICATE DEVICE Deknatel® Nonabsorbable Surgical Sutures, K153076 ### IV. DEVICE DESCRIPTION Deknatel Silk Suture is a nonabsorbable, sterile, surgical suture composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx mori (B. mori) of the family Bombycidae. Silk Suture is waxed, braided or twisted, and provided dyed (black) or undyed (natural white). Silk Suture meets all requirements established by the United States Pharmacopeia (USP) for Nonabsorbable Surgical Suture and is available in USP sizes 10-0 through 5 (metric sizes 0.2 through 7). The suture is supplied sterile, waxed, and braided or twisted. The suture is provided in a variety of lengths, with and without needles, with and without pledgets, and may be supplied in a variety of cut lengths or on ligating reels. Finished suture may be packaged in cartons as single packs, multipacks or procedure packs. # V. INDICATIONS FOR USE Deknatel Silk Surgical Sutures is indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, ophthalmic and neurological procedures. {4}------------------------------------------------ The Indications for Use statement for Deknatel Silk Surgical Sutures is identical to the predicate device. ## VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE The proposed Deknatel Silk Surgical Sutures have the same technology, indications for use and functional characteristics as the predicate system. The proposed modification is a dying process change to replace the current mordant, Sodium Dichromate with Ferrous Sulfate. A comparison of the technological characteristics of the proposed Deknatel Silk Surgical Sutures and the predicate has been performed. The results of this comparison demonstrate that the Silk Surgical Sutures are equivalent to the marketed predicate devices in performance characteristics. ### VII. PERFORMANCE DATA Non-clinical testing has been performed in accordance USP (United States Pharmacopeia) Nonabsorbable Sutures, 36-NF 31 <861> Sutures -Diameter, <871> Sutures- Needle Attachment, and <881>Tensile Strength in order to verify mordant material change of the proposed Deknatel Silk Surgical Sutures are substantially equivalent to the predicate devices. ### Biocompatibility Testing The biocompatibility evaluation for the Deknatel Silk Surgical Suture was conducted in accordance with FDA Blue Book Memorandum #G95-1 "Use of International Standards ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing," May 1, 1995, and International Standards ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by the FDA. The battery of testing included the following tests: - . Cytotoxicity - Sensitization ● - Irritation ● - Systemic toxicity ● - Subchronic toxicity - Genotoxicity ● - Implantation - Haemocompatibility - Pyrogen testing The Deknatel Silk Surgical Sutures is considered a permanent implant (> 30 days) and the nature of body contact is tissue/bone and blood. Deknatel Silk {5}------------------------------------------------ Suture is composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx mori (B. mori) of the family Bombycidae. Silk Suture is waxed with beeswax or a beeswax and paraffin mixture. Black silk suture is dyed with Logwood dye. ### VII. CONCLUSIONS Based upon the comparative test results, the proposed Deknatel Silk Surgical Sutures are substantially equivalent in performance to the predicate devices cleared to market via 510(k)s K153076.
