    The ClotTriever Thrombectomy System is intended for use in the peripheral vasculature.
Device Description

The ClotTriever Thrombectomy System is a single-use, sterile medical device designed for use in the peripheral vasculature. The ClotTriever Thrombectomy System is comprised of the ClotTriever Sheath and the ClotTriever Catheter. The ClotTriever Sheath consists of a reinforced polymeric sheath equipped with a self-expanding distal mesh funnel, a flush/aspiration port, and a proximal hemostatic valve. A dilator is provided to aid insertion. Other provided accessories include the funnel loading tool and a Large Bore 60 cc syringe. The ClotTriever Catheter consists of reinforced polymeric coaxial shafts terminating in an expandable coring element and thrombus collection bag. Two ports terminating in stopcocks are provided for de-airing the catheter shafts. To aid in fluoroscopic visualization, the Sheath dilator and ClotTriever Catheter distal tips are radiopaque.

AI/ML Overview

This document describes the ClotTriever Thrombectomy System, a medical device for removing thrombi and emboli from blood vessels. However, the provided text does not contain information about a study proving the device meets acceptance criteria in the context of an AI/algorithm performance study.

The document is a 510(k) premarket notification summary for an updated version of the ClotTriever Thrombectomy System, comparing it to a previously cleared predicate device. The "acceptance criteria" discussed are related to non-clinical engineering and material tests to demonstrate that the modified physical device is substantially equivalent to the predicate device, not performance benchmarks for an AI or algorithm.

Therefore, I cannot fulfill the request to describe the acceptance criteria and study proving the device meets those criteria, as well as the related details (sample size, experts, adjudication, MRMC, standalone, ground truth, training set details) because this information is not present in the provided text.

The "Non-Clinical Testing" section explicitly states: "Clinical testing was not required for the determination of substantial equivalence." This further confirms that no human-centric performance study (like an AI study would entail) was conducted or presented in this 510(k) submission.

Summary of what can be extracted regarding "acceptance criteria" and "study" for this physical device:

  • Acceptance Criteria and Reported Device Performance (Table): Not directly available in a table format for performance in the AI sense. The text mentions "Test results demonstrated that all acceptance criteria were met; therefore, the device conforms to established product specifications and intended use." The types of non-clinical tests that presumably had acceptance criteria are listed:
    • Visual & Dimensional Inspections
    • Guidewire Compatibility
    • Tensile testing
    • Test Conical Fittings with 6% Luer taper
    • (No specific performance metrics are given, only that criteria were met).
  • Sample size for the test set and data provenance: N/A for an AI/algorithm study. The "test set" here refers to the physical devices manufactured for non-clinical testing, not a dataset of patient images.
  • Number of experts used to establish ground truth & qualifications: N/A. Ground truth for these physical tests would be engineering specifications and measurements.
  • Adjudication method: N/A.
  • MRMC comparative effectiveness study: No. "Clinical testing was not required."
  • Standalone (algorithm only without human-in-the-loop performance): No, this is for a physical medical device.
  • Type of ground truth used: For the physical device, ground truth would be engineering specifications, material standards, and physical measurements.
  • Sample size for the training set: N/A.
  • How the ground truth for the training set was established: N/A.

Dear Mr. Gordon:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for
