Device Story

Surgical sutures (polypropylene, polyester, or polyamide) provided with or without stainless steel needles; used for soft tissue approximation and ligation. Suture materials include monofilament polypropylene, braided/silicone-coated polyester, and monofilament polyamide. Needles available in various geometries (taper, cutting, reverse cutting, etc.) and curvatures. Devices are sterile, single-use, and EO-sterilized. Used by clinicians in surgical settings to close wounds or ligate tissues. Benefits include secure tissue approximation during healing. Output is the physical suture material providing mechanical support to tissue.

Clinical Evidence

No clinical data. Bench testing only. Compliance with USP 43-NF 38:2020 standards for diameter, tensile strength, needle attachment, sterility, and bacterial endotoxins. Biocompatibility testing per ISO 10993 series (cytotoxicity, sensitization, irritation, systemic toxicity, genotoxicity, implantation, hemolysis) confirms safety.

Technological Characteristics

Non-absorbable synthetic sutures (polypropylene, polyester, polyamide). Polyester is braided/silicone-coated; others are monofilament. Stainless steel needles. EO sterilization (SAL 10-6). Complies with USP 43-NF 38:2020 and ISO 10993 standards. Shelf life 5 years.

Indications for Use

Indicated for general soft tissue approximation and/or ligation in patients requiring non-absorbable sutures. The device is intended for use for a maximum of 30 days.

Regulatory Classification

Identification

Natural nonabsorbable silk surgical suture is a nonabsorbable, sterile, flexible multifilament thread composed of an organic protein called fibroin. This protein is derived from the domesticated species Bombyx mori (B. mori ) of the family Bombycidae. Natural nonabsorbable silk surgical suture is indicated for use in soft tissue approximation. Natural nonabsorbable silk surgical suture meets the United States Pharmacopeia (U.S.P.) monograph requirements for Nonabsorbable Surgical Suture (class I). Natural nonabsorbable silk surgical suture may be braided or twisted; it may be provided uncoated or coated; and it may be undyed or dyed with an FDA listed color additive.

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.

Therefore, this item does not impact the safety and effectiveness. ### Different Analysis 4- Suture Size The Suture Size of the proposed device is within the scope of the Suture Size of predicate devices. The proposed device has been demonstrated to comply the requirements listed in USP Monograph of Non-Absorbable Surgical Suture. Therefore, this item does not impact the safety and effectiveness. ### Different Analysis 5- Suture Length The Suture Length of the proposed device is within the scope of the Suture length of predicate devices. The proposed device has been demonstrated to comply the requirements listed in USP Monograph of Non-Absorbable Surgical Suture. Therefore, this item does not impact the safety and effectiveness. ### Different Analysis 6- Needle Biocompatibility The needle biocompatibility of Proposed Device and Predicate Device should meet the requirements of ISO10993 series standards; although we do not know the specific test items of Predicate Device, but the needle biocompatibility tests of Proposed Device have been performed in Cytotoxicity Test Report, Max Sensitization Test Report, Intracutaneous Reactivity Test Report, Acute Systemic Toxicity Test Report, Pyrogenicity Test Report, Hemolysis Test Report (Direct contact), Hemolysis Test Report (Indirect contact). These studies can demonstrate the needle biocompatibility of Proposed Device. Therefore, this item is considered to be substantially equivalent. ## Different Analysis 7- Suture Biocompatibility The biocompatibility of Proposed Device and Predicate Device should meet the requirements of ISO10993 series standards; although we do not know the specific test items of Predicate Device, but the biocompatibility tests of of Proposed Device have been performed in Cytotoxicity, Max Sensitization, Intracutaneous Reactivity Test. Acute Systemic Toxicity Test. Genotoxicity, Pyrogenicity, Muscle Implantation Subacute/Subchronic Toxicity Study, Hemolysis Test (Direct Contact) and Hemolysis Test (Indirect Contact). These studies can demonstrate the biocompatibility of Proposed Device. Therefore, this item is considered to be substantially equivalent. #### 9. Substantially Equivalent (SE) Conclusion Based on the comparison and analysis above, the proposed devices are determined to be Substantially Equivalent (SE) to the predicate device.
