    Intended Use

    CM005 Standard Topical Skin Adhesive is indicated for topical application only, to hold closed easily approximated skin edges of wounds from surgical incisions, including incisions from minimally invasive surgery, and simple, thoroughly cleansed, trauma-induced lacerations. CM005 STANDARD Topical Skin Adhesive may be used in conjunction with, but not in place of deep dermal stitches. CM005 STANDARD Topical Skin Adhesive should be applied by trained medical or nursing staff.

    CM004 Mini Topical Skin Adhesive is indicated for topical application only, to hold closed easily approximated skin edges of wounds from surgical incisions, including incisions from minimally invasive surgery, and simple, thoroughly cleansed, trauma-induced lacerations. CM004 Mini Topical Skin Adhesive may be used in conjunction with, but not in place of deep dermal stitches. CM004 Mini Topical Skin Adhesive should be applied by trained medical or nursing staff.

    Device Description

    CM005 Standard Topical Skin Adhesive is a sterile, liquid topical skin adhesive containing a monomeric (2-octyl cyanoacrylate) formulation and the colorant D & C Violet No. 2. It is provided as a single-use applicator in a blister package. The pen style applicator is composed of a crushable glass ampoule contained within a plastic tube and plastic enclosure with silicone brush tip. When applied to the skin, the liquid adhesive polymerizes within minutes.

    AI/ML Overview

    This document is a 510(k) summary for medical devices (CM005 Standard and CM004 Mini Topical Skin Adhesives) and as such does not contain a study addressing acceptance criteria in the manner requested (i.e., with statistical performance metrics against a defined ground truth, typical for AI-software devices).

    The provided text describes performance testing conducted to demonstrate substantial equivalence to predicate devices, rather than a study with acceptance criteria against a clinical outcome or expert ground truth for an AI/software device. The devices are topical skin adhesives, not AI/software devices. Therefore, a table of acceptance criteria vs. device performance, sample sizes for test/training sets, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, or methods for establishing ground truth for training data are not applicable in the context of this document.

    The "acceptance criteria" for these devices are demonstrated through a series of performance tests and biocompatibility assessments, showing that they are substantially equivalent to already cleared predicate devices.

    Here's a summary of the type of performance criteria and tests carried out (as described in the document), rather than a direct answer to the prompt's table due to the nature of the device:

    1. A table of acceptance criteria and the reported device performance

    Since this is not an AI/software device, there aren't explicit numeric "acceptance criteria" in the traditional sense of diagnostic accuracy (e.g., sensitivity, specificity). Instead, substantial equivalence is demonstrated by performing various tests to show that the new devices perform comparably to predicate devices. The document states:

    "It was determined through the testing (Bench and Animal) performed in this 510(k) submission, that the subject devices are substantially equivalent to the predicate devices and any minor differences in performance does not affect safety or efficacy."

    The specific performance tests conducted were:

    Performance TestDescription / Outcome
    Lap-shear strengthTested in accordance with ASTM F2255-05. (Implied: Demonstrated performance comparable to predicate).
    T-peel adhesion strengthTested in accordance with ASTM F2256-05. (Implied: Demonstrated performance comparable to predicate).
    Adhesive strength in tensionTested in accordance with ASTM F2258-05. (Implied: Demonstrated performance comparable to predicate).
    Wound closure strengthTested in accordance with ASTM F2458-05. (Implied: Demonstrated performance comparable to predicate).
    Adhesive degradation studyPerformed. (Implied: Demonstrated degradation properties comparable to predicate or acceptable for safety/efficacy).
    Heat of polymerizationMeasured. (Implied: Demonstrated polymerization characteristics comparable to predicate or acceptable for safety/efficacy).
    ViscosityMeasured. (Implied: Demonstrated viscosity characteristics comparable to predicate or acceptable for manufacturing/application).
    Set timeMeasured. (Implied: Demonstrated set time comparable to predicate or acceptable for clinical use).
    Microbial barrier testingPerformed. "In vitro studies have shown that following application and polymerization, CM005 STANDARD Topical Skin Adhesive acts as a physical barrier to prevent microbial penetration as long as the adhesive film remains intact. Clinical studies were not conducted to demonstrate microbial barrier properties and a correlation between microbial barrier properties and a reduction in infection have not been established."
    Device Yield and Quality of FilmPerformed. (Implied: Demonstrated acceptable device yield and film quality).
    Flow ControlPerformed. (Implied: Demonstrated acceptable flow control).
    Animal wound healing studyPerformed. (Implied: Demonstrated wound healing characteristics comparable to predicate or acceptable for safety/efficacy).
    BiocompatibilityTests performed per ISO 10993-1: Solvent compatibility, chemical characterization, toxicological risk assessment, cytotoxicity, sensitization, intracutaneous reactivity, material mediated pyrogenicity, acute toxicity, subacute toxicity, implantation. (Implied: All tests passed, demonstrating biological safety).

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    The document does not specify sample sizes for each individual test or their provenance. The tests were bench and animal studies (laboratory and pre-clinical, respectively).

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    This is not applicable to a non-AI/software device submission. Ground truth for these physical and biochemical tests is established by standardized testing protocols (e.g., ASTM standards) and animal study observations.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    Not applicable for a non-AI/software device. The tests follow established protocols.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    Not applicable, as this is not an AI-assisted device.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    Not applicable, as this is not an AI/software device.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    For the performance tests, the "ground truth" is defined by the accepted results or outcomes of standardized physical, chemical, and biological tests (e.g., tensile strength measurements, viscosity values, lack of cytotoxicity as per ISO 10993-1). For the animal wound healing study, the ground truth would be histological assessment and observation of wound closure and healing characteristics.

    8. The sample size for the training set

    Not applicable, as this is not an AI/software device.

    9. How the ground truth for the training set was established

    Not applicable, as this is not an AI/software device.
