    Intended Use

    The MicroSpan Hysteroscope is used to permit viewing of the cervical canal and the uterine cavity for the purpose of performing diagnostic and surgical procedures.

    Device Description

    The MicroSpan Hysteroscope is a small diameter, rigid, fiberoptic hysteroscope without through lumens. The device consists of an outer stainless steel shaft, inner illumination fibers, and an imaging fiber bundle. At one end of the imaging bundle is the distal lens and at the other is the rotatable eyepiece. An endoscopic light source is connected to the light post of the hysteroscope through compatible light cables. If desired, the eyepiece can be connected through a focusing optical coupler to a camera head which carries the image by cable to the camera.

    AI/ML Overview

    The provided 510(k) summary for the MicroSpan Hysteroscope does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria in the context of an AI/algorithm-driven medical device.

    The document describes a physical medical device (a hysteroscope) and its performance is evaluated based on optical, mechanical, thermal, and biocompatibility characteristics, along with the effect of simulated reuses. It is a traditional medical device, not an AI or algorithm-based device.

    Therefore, I cannot extract the following information that would be relevant to an AI/algorithm study:

    • A table of acceptance criteria and the reported device performance (in terms of AI metrics like sensitivity, specificity, accuracy)
    • Sample sizes for test or training sets
    • Data provenance
    • Number/qualifications of experts for ground truth
    • Adjudication methods
    • MRMC comparative effectiveness study results
    • Standalone algorithm performance
    • Type of ground truth used (pathology, outcomes data, etc.)
    • How ground truth was established for training or test sets

    Instead, the document details non-clinical tests for a physical device:

    • Performance Summary: "Non-clinical tests were performed to demonstrate that the device performed according to its description. Testing included evaluation of optical and mechanical characteristics of the device and the effect of simulated reuses on these characteristics. The device was also evaluated for its thermal characteristics and biocompatibility."

    This summary indicates that the "acceptance criteria" would be standards for these physical and functional characteristics, and the "study" would be the non-clinical tests described. However, specific numerical targets for these characteristics are not provided in this summary.

    Intended Use

    The MicroSpan Hysteroscope Sheath is indicated for use in providing access to the uterine cavity for the Imagyn Hysteroscope or other hysteroscopic instruments during diagnostic and operative hysteroscopic procedures.

    Device Description

    The MicroSpan Hysteroscope Sheath is offered with irrigation/insufflation and aspiration ports and an instrument channel. The device is provided sterile, for single-use, and is made from both metal and plastic components.

    AI/ML Overview

    This document is a 510(k) summary for a medical device called the "MicroSpan Hysteroscope Sheath." It describes the device, its intended use, and comparisons to predicate devices. However, the information provided does not include details about acceptance criteria or a study that proves the device meets specific performance metrics in the way you've outlined for an AI/ML medical device.

    The provided text describes a traditional hardware medical device (a hysteroscope sheath), not an AI/ML software device. Therefore, many of your requested points (like sample size for test/training sets, ground truth establishment, MRMC studies, standalone algorithm performance, number of experts for ground truth) are not applicable to this type of device submission.

    Here's a breakdown of what can be extracted and what is missing based on the provided text, recognizing the difference in device type:

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

    Acceptance CriteriaReported Device Performance
    For the MicroSpan Hysteroscope Sheath (based on "Performance Summary")
    Adequate performance for intended use.Non-clinical tests demonstrated the device performed according to its description and intended use.
    Leak testing shows adequate performance.Leak testing performed showed adequate performance.
    Flow testing shows adequate performance.Flow testing performed showed adequate performance.

    Missing: Specific quantitative acceptance criteria (e.g., "leak rate less than X mL/minute," "flow rate greater than Y mL/minute at Z pressure"). The description is very general.


    Regarding the other points, they are largely not applicable or not provided in the context of this traditional medical device summary:

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

    • Not Applicable/Not Provided: For a physical device like a hysteroscope sheath, "test set" in the context of data for AI/ML algorithms doesn't apply. The "tests" performed were likely bench tests on a specific number of manufactured units. The document does not specify the number of units tested.

    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)

    • Not Applicable: "Ground truth" in the AI/ML sense (e.g., expert consensus on image interpretation) is not relevant for a hysteroscope sheath. Device performance would be assessed against engineering specifications.

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

    • Not Applicable: This relates to expert review for AI/ML ground truth, which doesn't apply here.

    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: This type of study is for evaluating observer performance with or without AI assistance, which is not relevant for a physical medical instrument like a hysteroscope sheath.

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

    • Not Applicable: This refers to AI algorithm performance without human interaction, which is not applicable to this physical device.

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

    • Not Applicable/Information Not Detailed: For a physical device, "ground truth" would be engineering specifications and functional requirements. The document mentions "non-clinical tests" and "leak and flow testing," implying performance was measured against predetermined criteria, but the specifics of these criteria are not provided.

    8. The sample size for the training set

    • Not Applicable: There is no "training set" in the AI/ML sense for this device.

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

    • Not Applicable: There is no "training set" or "ground truth" establishment in the AI/ML sense for this device.
