    Intended Use

    Under the supervision of a healthcare professional, MANUKA FILL wound dressing is indicated for the management of: > Leg Ulcers A Pressure Ulcers > 1st and 2nd Degree Burns > Diabetic Foot Ulcers > Surgical Wounds > Trauma Wounds MANUKA FILL wound dressing provides a moist wound environment. A moist wound environment allows autolytic debridement of necrotic tissue.
    MANUKA FILL wound dressing may be used Over-The-Counter for the management of: > Minor Abrasions > Minor Lacerations > Minor Cuts > Minor Scalds and Minor Burns MANUKA FILL wound dressing provides a moist wound environment. A moist wound environment allows autolytic debridement of necrotic tissue.

    Device Description

    MANUKA FILL wound dressing is a sterile, single-use, wound care dressing that helps maintain a moist wound environment conducive to wound healing. The primary device consists of 100% Leptospermum scoparium honey from New Zealand sealed into low-density polyethylene (LDPE) tubes and sterilized using gamma irradiation.

    AI/ML Overview

    The provided document outlines the acceptance criteria and the study conducted for the MANUKA FILL wound dressing, focusing primarily on nonclinical testing for substantial equivalence to predicate devices.

    1. Table of Acceptance Criteria and Reported Device Performance

    Test TypeAcceptance CriteriaReported Device Performance
    BiocompatibilityIn accordance with ISO 10993-1 and FDA Biocompatibility Matrix for cytotoxicity, skin irritation, and skin sensitization.MANUKA FILL wound dressing met the requirements for cytotoxicity, skin irritation, and skin sensitization.
    Wound Healing StudyTest articles should not impair healing and be as safe and effective as predicate devices.The test articles did not impair healing and were determined to be as safe and effective as the predicate devices (K121227 and K072068) in a full-thickness dermal wound study in swine.
    Sterilization ValidationDevice meets applicable sterilization standards.MANUKA FILL wound dressing met the acceptance criteria for sterilization validation.
    Shelf-LifeDevice maintains performance under accelerated and real-time conditions.MANUKA FILL wound dressing met the acceptance criteria for shelf-life under accelerated and real-time conditions.
    Packaging ValidationDevice packaging integrity and protection maintained.MANUKA FILL wound dressing met the acceptance criteria for packaging validation.

    2. Sample Size Used for the Test Set and Data Provenance

    The document explicitly mentions a "wound healing study was conducted to assess the impact of repeated application of MANUKA FILL to full-thickness dermal wounds in swine." However, it does not specify the sample size used for this study.

    The data provenance for the nonclinical testing appears to be prospective, as it describes tests conducted specifically for the submission of the MANUKA FILL wound dressing. The document states, "All tests were performed by North American Science Associates (NAMSA)," suggesting the data was generated in a controlled, scientific testing environment. The country of origin for the data is not explicitly stated, but NAMSA has facilities in the U.S. and Europe. The honey itself is stated to be from New Zealand.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

    For the nonclinical studies, particularly the biocompatibility and wound healing studies, the "ground truth" refers to the scientific assessment of the device's performance against established standards. The document does not specify the number of experts or their specific qualifications involved in establishing the ground truth or evaluating the results of these nonclinical tests. It only states that "All tests were performed by North American Science Associates (NAMSA)," which is a contract research organization specializing in medical device testing.

    4. Adjudication Method for the Test Set

    The document does not mention any human adjudication method (like 2+1 or 3+1). The studies described are nonclinical, focusing on laboratory and animal model testing, which typically involves quantitative measurements and adherence to scientific protocols rather than expert consensus on subjective interpretations.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is typically performed for diagnostic or imaging devices where human readers interpret data, and the document describes a wound dressing, which is a therapeutic device. There is no mention of comparing human reader performance with or without AI assistance.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    No, a standalone (algorithm-only) performance study was not done. The MANUKA FILL wound dressing is a physical medical device, not a software algorithm, and therefore this type of study is not applicable.

    7. The Type of Ground Truth Used

    For the nonclinical tests:

    • Biocompatibility: Ground truth was based on established ISO 10993-1 standards and the FDA Biocompatibility Matrix, which define acceptable levels for cytotoxicity, skin irritation, and skin sensitization.
    • Wound Healing Study: Ground truth was based on observed healing outcomes in swine models, comparing the device's performance to predicate devices and assessing whether healing was impaired. This is a form of outcomes data in an animal model.
    • Sterilization, Shelf-Life, Packaging Validation: Ground truth was based on established industry and regulatory standards for these performance requirements.

    8. The Sample Size for the Training Set

    The document describes nonclinical studies for substantial equivalence. It does not mention a "training set" because this term is relevant to machine learning or AI algorithm development, which is not applicable to this physical wound dressing device.

    9. How the Ground Truth for the Training Set Was Established

    As there is no training set for this type of device and study, this information is not applicable.
