    Intended Use

    Sofsilk™ Coated Braided Silk Sutures are indicated for use in soft tissue approximation and/or ligation.

    Device Description

    Sofsilk™ 6/0 and 7/0 black braided silk sutures are nonabsorbable, sterile, non-mutagenic surgical sutures composed of natural proteinaceous silk fibers called fibroin. This protein is derived from the domesticated silkworm species Bombyx mori of the family bombycidae. The silk fibers are treated to remove the naturally-occurring sericin gum and braided to produce Sofsilk™ surgical silk sutures. The braided sutures are coated uniformly with silicone to reduce capillarity and to increase surface lubricity, which enhances handling characteristics, ease of passage through tissue, and knot run-down properties. Sofsilk™ sutures are colored black with Logwood extract (21CFR73.1410). Sofsilk™ sutures meet all requirements established by the United States Pharmacopeia (USP) and the European Pharmacopeia (EP) for nonabsorbable surgical sutures, Sofsilk™ Coated Braided Silk Suture. Sofsilk™ sutures are indicated for use in soft tissue approximation and/or ligation.

    AI/ML Overview

    The provided text is a 510(k) summary for the Sofsilk™ Coated Braided Silk Suture. It details the device's characteristics, indications for use, and a comparison to a predicate device. However, it does not contain information about an AI/ML-based device or its performance criteria.

    Therefore, I cannot provide the requested information regarding acceptance criteria, study details, sample sizes, expert involvement, ground truth, or MRMC studies, as these aspects are not discussed in the provided document. The document describes a traditional medical device (surgical sutures) and its regulatory clearance based on substantial equivalence, primarily through bench testing for physical and mechanical performance, and biocompatibility.

    The "study" mentioned refers to mechanical and physical bench tests of the suture, not a clinical or AI performance study.

    Here's what the document does provide regarding the device's performance evaluation:

    • Acceptance Criteria (implied standards compliance):

      • Meets or exceeds requirements of U.S.P. (United States Pharmacopeia) for nonabsorbable surgical sutures.
      • Meets or exceeds requirements of E.P. (European Pharmacopeia) for nonabsorbable surgical sutures.
      • Compliant with ISO 10993-1:2018 "Biological evaluation of medical devices-Part 1: Evaluation and testing" for biocompatibility.
      • Sterility Assurance Level (SAL) of 10^-6 for ETO sterilization.
    • Reported Device Performance (bench tests):

      • USP/EP diameter: Tested, found equivalent to predicate.
      • USP needle attachment: Tested, found equivalent to predicate.
      • USP tensile strength: Tested, found equivalent to predicate.
      • Biocompatibility: Evaluated and confirmed compliant with ISO 10993-1 for its intended patient contact profile.
      • Shelf life: Stability studies conducted, proposed 5-year shelf life demonstrated.

    The document explicitly states: "This premarket submission did not rely on the assessment of clinical performance data to demonstrate substantial equivalence." This further confirms that there was no clinical study, let alone one involving AI/ML performance.
