The summary describes a mechanical system for thrombus removal and does not mention any AI or ML components or functions.
Yes
The device is indicated for the non-surgical removal of emboli and thrombi from blood vessels and for injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel, which are therapeutic actions.
No
The device is described as a system for the non-surgical removal of emboli and thrombi from blood vessels and for the injection/aspiration of fluids, indicating a therapeutic rather than diagnostic function.
No
The device description clearly outlines physical components (catheters, aspirator) and mechanical actions (deployment, retraction, aspiration), indicating it is a hardware-based medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used outside of the body.
- Device Function: The Flow Triever Retrieval/Aspiration System is a catheter-based system used inside the body (in the peripheral vasculature and for pulmonary embolism) to physically remove blood clots. It is a therapeutic device, not a diagnostic test performed on a sample.
- Intended Use: The intended use clearly states "non-surgical removal of emboli and thrombi from blood vessels" and "Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel." These are interventional procedures, not diagnostic tests.
Therefore, the Flow Triever Retrieval/Aspiration System is a medical device used for treatment, not an in vitro diagnostic device.

Device Description
The FlowTriever Retrieval/Aspiration System is a single-use over-the-wire catheter-based system for the minimally invasive treatment of thromboemboli in the peripheral vasculature. The system is comprised of three main components packaged separately:
Aspiration Guide Catheter FlowTriever Catheter (available in 4 sizes: 6-10 mm, 11-14 mm, 15-18 mm, and 19-25 mm) Retraction Aspirator
The FlowTriever Catheter is inserted through the Aspiration Guide Catheter and advanced to the thrombus. Self-expanding wireform disks are deployed to engage thrombus by retracting the outer Delivery Catheter. The hand-lever operated Retraction Aspirator simultaneously aspirates fluids and retracts the FlowTriever Catheter with thrombus into the Aspiration Guide Catheter to capture clot and restore blood flow.

Non-Clinical Testing:
In accordance with the Design Failure Modes and Effects Analysis, verification and validation testing were identified to support the substantial equivalence of the modified FlowTriever Retrieval/Aspiration System. This testing demonstrated compliance with relevant product specifications. These tests included:
- Visual & Dimensional Inspections
- Deployment Force, Wireform Catheter from Delivery Catheter
- Retraction Force, Wireform Catheter into Delivery Catheter
- Retraction Force, Wireform Catheter into Guide Catheter
- Simulated use Track and Tensile
- Simulated Thrombus Removal Characterization
- 25 mm Wireform Radial Expansion Force
Assessment of the 2-year shelf-life data for the predicate device concluded that the existing accelerated aging studies can be leveraged to support 2-year shelf-life for the proposed 25 mm FlowTriever Catheter.
In consideration of the biological safety for the proposed 25 mm FlowTriever Catheter was leveraged off existing data for the predicate devices with regards to the new colorant (Cool Grey 7C) and the increased surface area of Nitinol.
Clinical testing was not required for the determination of substantial equivalence.
Test results demonstrated that all acceptance criteria were met; therefore, the device conforms to established product specifications and intended use.
Conclusion:
The proposed device modifications to the FlowTriever Retrieval/Aspiration System do not change its intended use or raise different questions of safety and effectiveness. With consideration of the results of the testing leveraged from K181325 and K180329, it can be concluded that the proposed FlowTriever Retrieval/Aspiration System is substantially equivalent to the predicate devices.

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.
