    AI/ML Overview

    I am sorry, but based on the provided text, there is no information about acceptance criteria, device performance described by a study, sample sizes, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, or training set details.

    The document is a 510(k) clearance letter from the FDA for a device called "Acidified Tyrodes Solution." It primarily confirms that the device is substantially equivalent to a legally marketed predicate device and outlines regulatory compliance requirements.

    The "Indications for Use" section states: "To be used for the softening of the embryo zona during assisted reproductive procedures." This indicates the intended purpose of the product but does not provide any performance metrics or study details.

    Device Name :

    MEDI-CULT ACIDIFIED TYRODES SOLUTION- MEDIUM; INTERNAL CATALOG NUMBERS (1060)

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    For drilling of the zona pellucida.

    Device Description

    Acidified Tyrodes Solution is a ready-to-use product with a pH between 2.3 and 2.5 for zona perforation.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and study information for Medi-Cult Acidified Tyrodes Solution, based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria CategorySpecific CriteriaReported Device Performance
    Product PropertiespHBetween 2.3 and 2.5
    Quality ControlBioburdenProduction-test (passed, implied)
    Integrity filterProduction-test (passed, implied)
    SterilityQC-test (passed, implied)
    pHQC-test (matched specification, implied)
    Clinical PerformanceSafetyNo registered complaints, no evidence of serious adverse events in the last 1.5 years
    EffectivenessRoutinely used for zona pellucida perforation, specific clinical testing cited

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

    • Sample Size: Not explicitly stated as a distinct "test set" in the context of a controlled trial with a defined number of cases. The clinical support comes from established use and a published study.
    • Data Provenance: The text mentions:
      • "initial clinical testing of Medi-Cult acidified Tyrodes has been done by Dr. Alan Handyside, Dept. Of Obstetrics and Gynecology, St. Thomas' Hospital, Londn, UK and by Søren Ziebe, the National Hospital, Copenhagen, Denmarke." This implies prospective clinical observation/use.
      • "The culture media from Medi-Cult have been used by many European IVF-units since the end of the 1980'ties." This suggests a long history of retrospective use data.
      • One specific publication is cited: "Søren Ziebe, Anders Nyboe Andersen, Anne-Grethe Andersen, Anne Lis Mikkelsen and Svend Lindenberg. Results of intracytoplasmic sperm injection in relation to indication Acta Obstetricia et Gynecological Scandinavica 1997; 335-339." This is a prospective clinical study, though the specific number of cases utilizing the Medi-Cult solution solely is not broken out.

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

    This type of information is not applicable to this device and its submission. The product is a chemical solution for a specific mechanical action (zona drilling). "Ground truth" in this context would likely refer to the physical effect of the solution (e.g., successful zona perforation) and the subsequent clinical outcomes (e.g., fertilization rates, pregnancy rates). Experts involved would be the clinicians performing the IVF procedures using the solution. The text cites:

    • Dr. Alan Handyside, Dept. Of Obstetrics and Gynecology, St. Thomas' Hospital, London, UK.
    • Søren Ziebe, the National Hospital, Copenhagen, Denmark.
    • Other unnamed "many European IVF-units."

    Their qualifications are implied by their roles in Obstetrics and Gynecology departments and IVF units, indicating expertise in reproductive medicine.


    4. Adjudication Method for the Test Set

    This is not applicable as there's no mention of a formal adjudication process for a "test set" in the context of expert review for image-based or diagnostic device performance. The assessment is based on clinical outcomes and the absence of adverse events.


    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

    This is not applicable. This device is a chemical solution, not an AI-powered diagnostic or interpretive tool. Therefore, a MRMC study comparing human reader performance with or without AI assistance is irrelevant.


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

    This is not applicable. As a chemical solution, there is no "algorithm" or standalone "performance" in the sense of an AI or software device. The device's function is purely chemical/physical.


    7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

    The ground truth for this device's effectiveness relies on:

    • Clinical Outcomes Data: Successful zona drilling (implied by routine use), subsequent fertilization, and embryo development (implied by the clinical study reference). The stated indication is "For drilling of the zona pellucida."
    • Absence of Adverse Events: This serves as ground truth for safety.
    • Published Data: The product is "based on published data" regarding acidified Tyrodes solution for zona perforation.

    8. The Sample Size for the Training Set

    This is not applicable. This device is a chemical solution, not a machine learning model. Therefore, there is no "training set."


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

    This is not applicable for the same reason as above (no training set).
