No
The device description and performance studies focus on mechanical aspects of thrombus removal and do not mention any AI/ML components or algorithms.
Yes
The device is indicated for "non-surgical removal of soft thrombi and emboli from blood vessels," which directly addresses a medical condition to restore health.
No
Explanation: The device description and intended use clearly state that the system is for the "non-surgical removal of soft thrombi and emboli from blood vessels" and for "injection, infusion, and/or aspiration of contrast media and other fluids." These are interventional/therapeutic functions, not diagnostic ones. While it mentions aiding "fluoroscopic visualization," this is for guiding the intervention, not for diagnosing a condition.
No
The device description explicitly details physical components like catheters, sheaths, funnels, ports, valves, dilators, and syringes, 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:
- Intended Use: The intended use is the "non-surgical removal of soft thrombi and emboli from blood vessels" and "Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel." This describes a therapeutic and interventional procedure performed directly on the patient's body, not a test performed on a sample taken from the body.
- Device Description: The description details a system of catheters and sheaths designed for physical manipulation within blood vessels. This is consistent with a medical device used for treatment or intervention, not for diagnostic testing of biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other components typically associated with in vitro diagnostic tests.
In vitro diagnostics are tests performed on samples taken from the human body to provide information about a person's health. This device is used within the body for a therapeutic purpose.

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 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 60 cc syringe. The ClotTriever Catheter consists of polymeric coaxial shafts terminating in an expandable coring element and thrombus collection bag. At the proximal end of the catheter is a handle used to enable tensioning of the coring element. Two ports terminating in stopcocks are provided for de-airing the catheter shafts. To aid in fluoroscopic visualization, the dilator and ClotTriever Catheter distal tips are radiopaque.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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 ClotTriever Thrombectomy System to the predicate device. This testing demonstrated compliance with relevant product specifications. These tests included:
- Visual & Dimensional Inspections
- Retraction Force of Handle
- Syringe Leak Testing
- Syringe Vacuum Testing
- Syringe Tensile Testing
- Clot burden Removal Performance Test
- Simulated Use, Tensile Test
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. Based upon the same intended use and principle of operation, technology, and nonclinical testing it is concluded that the modified ClotTriever Thrombectomy System is substantially equivalent to the predicate device.

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.
