    ERB ENDORECTAL BALLOON

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

    The ERB is a single use, inflatable, non-powered positioning device placed in the rectum to immobilize the prostate in patients undergoing radiation therapy. The device is intended to be used during all the phases of radiation therapy, including treatment planning, image verification, and radiotherapy delivery.

    Device Description

    The ERB is designed as an immobilizer to assist in positioning the prostate in a more predictable and reproducible location during Computed Tomography (CT) exam and Xray, when these imaging techniques are used for Radiation Therapy (RT) planning. The ERB is inserted into the rectum and inflated prior to the start of a CT scan or RT therapy procedure. The device stabilizes the prostate once the device is inflated. The ERB is deflated and removed after each individual scan or therapy procedure is complete, and a new balloon is used in the next therapy session. The ERB is designed for single use, is provided non-sterile to the end user, and is not intended to be sterilized by the end user. The ERB consists of a balloon and tubing can be inflated with either water or air. The device can be locked into place once inserted into the rectum with a locking stopper.

    AI/ML Overview

    The provided text is a 510(k) summary for the ERB Endorectal Balloon, a Class II medical device. The document primarily focuses on establishing substantial equivalence to a predicate device rather than presenting a standalone study of the device's performance against specific acceptance criteria.

    However, it does mention "Non-Clinical Testing" and "Performance Data" in a general sense. Based on the provided text, a detailed table of acceptance criteria and reported device performance with specific metrics cannot be fully populated. The document only states that "Product testing was completed and met all of the acceptance criteria. Testing included dimensional, visual, mechanical and performance." and "All necessary verification and validation testing has been performed for the ERB to assure substantial equivalence to the predicate devices."

    Here's an attempt to extract the information requested, with limitations due to the nature of the provided document:


    1. Table of Acceptance Criteria and Reported Device Performance

    Note: The provided document does not list specific quantitative acceptance criteria or detailed performance metrics. It generally states that testing was completed and met all acceptance criteria, and that the device's performance attributes are equivalent to the predicate. Therefore, the "Reported Device Performance" column reflects generalized statements from the document.

    Acceptance Criteria CategoryReported Device Performance
    DimensionalMet all acceptance criteria. Dimensions are equivalent to predicate (minor differences in length/diameter not affecting safety/efficacy)
    VisualMet all acceptance criteria.
    MechanicalMet all acceptance criteria.
    PerformanceMet all acceptance criteria. Performance attributes are equivalent to predicate.
    BiocompatibilityPassed ISO10993 testing (Cytotoxicity, Sensitization, Irritation). Materials are suitable for use and have been used in numerous previously cleared products.

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

    The document does not specify the sample size used for the test set in non-clinical testing. It only mentions "Product testing" and "All necessary verification and validation testing."

    Data Provenance: The testing appears to be non-clinical (laboratory/bench testing) rather than clinical studies on human subjects. The document does not specify the country of origin for the data or if it was retrospective or prospective, beyond stating that Edge Medical, LLC performed the testing.


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

    This information is not applicable and not provided in the document. The testing described is non-clinical (dimensional, visual, mechanical, performance, biocompatibility) of a physical device, not an AI/software device that would require expert-established ground truth for a test set.


    4. Adjudication Method for the Test Set

    This information is not applicable and not provided in the document for the reasons stated in point 3.


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

    No, an MRMC comparative effectiveness study was not done. This type of study is typically performed for imaging interpretation devices, often involving AI assistance for human readers. The ERB Endorectal Balloon is a physical medical device for prostate immobilization during radiation therapy.


    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, as the ERB is a physical device, not an algorithm.


    7. The Type of Ground Truth Used

    For the non-clinical testing mentioned (dimensional, visual, mechanical, performance), the "ground truth" would be established by engineering specifications, material standards, and benchmark measurements against known properties of the device and its predicate. For biocompatibility, the ground truth is established by adherence to ISO10993 standards.


    8. The Sample Size for the Training Set

    This information is not applicable and not provided in the document. The ERB is a physical medical device, not an AI/machine learning algorithm that requires a training set.


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

    This information is not applicable and not provided in the document for the reasons stated in point 8.
