Intended Use

The 7.0 Fr. Endobronchial Blocker is intended for use to differentially intubate a patient's bronchus in order to isolate the left or right lung for procedures which require one-lung ventilation.

Device Description

The catheter contains a balloon at its distal tip. The proximal end of the catheter is made up of a Y-fitting. One port of the Y-fitting is connected to a pilot balloon assembly. This balloon assembly facilitates inflation of the distal balloon and maintains inflation until it is released. The other port of the Y-fitting connects to the through lumen of the catheter which incorporates a removable looped guide wire that is used to help traverse the catheter along the length of a previously positioned bronchoscope. When the balloon catheter has been advanced to either the right or left bronchus, the guide loop is removed and discarded leaving the through lumen open.

AI/ML Overview

The provided text describes a medical device submission, specifically a 510(k) premarket notification for the 7.0 Fr. Endobronchial Blocker. It details the device's description, indications for use, and a comparison to predicate devices for substantial equivalence. However, this document does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria, as typically found in reports for AI/ML-driven devices or complex diagnostic systems.

The "Test Data" section only generally states:

The 7.0 Fr. Endobronchial Blocker was subjected to the following tests to assure reliable design and performance under the specified testing parameters. These tests include:

  • Performance Testing
  • Biocompatibility Testing

The results of these tests provide reasonable assurance that the device has been designed and tested to assure conformance to the requirements for its use as an Endobronchial Blocker.

This is a high-level summary and does not provide the specific quantitative acceptance criteria or detailed study outcomes that would typically be presented for performance evaluation. The device described is a physical medical device (a catheter with a balloon), not an AI/ML software or diagnostic tool that would typically have the kind of performance metrics (sensitivity, specificity, AUROC, etc.) and associated study methodologies requested in the prompt.

Therefore, I cannot populate the table and answer the subsequent questions based on the provided text. The document focuses on regulatory clearance based on substantial equivalence to predicate devices, rather than a detailed clinical performance study with acceptance criteria for a novel diagnostic or AI-assisted function.

To answer your request, here's what would be provided if the document contained the information:

  4. 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:

    • MRMC Study Done: (e.g., Yes)
    • Effect Size: (e.g., Human readers showed a statistically significant increase in diagnostic accuracy of 8% (e.g., from 75% to 83%) when using AI assistance compared to without AI assistance, with a 95% CI of [5%, 11%]).
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Standalone Study Done: (e.g., Yes, the performance metrics in the table above represent standalone algorithm performance.)
  6. The type of ground truth used:

    • Ground Truth Type: (e.g., Expert consensus as described in point 4, confirmed by pathology reports for a subset of cases.)
  7. The sample size for the training set:

    • Training Set Sample Size: (e.g., 10,000 cases)
  8. How the ground truth for the training set was established:

    • Training Set Ground Truth Establishment: (e.g., Established by consensus of 2 junior radiologists, verified by a senior radiologist for a random 10% subset, supplemented with metadata from electronic health records including pathology and operative reports.)

Dear Ms. Lavender:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
