ClotTriever Thrombectomy System
FDA Clearance Information
The ClotTriever Thrombectomy System was cleared by the FDA via the 510(k) pathway on April 9, 2018. It is manufactured by Inari Medical and classified as a Class II device.
What It Is
FDA-Cleared Indications
- Mechanical thrombectomy for removing thrombi from the peripheral vasculature.
- Use with aspiration to remove thrombus from peripheral blood vessels.
- FDA-cleared as a Class II peripheral mechanical thrombectomy device under product code QEW and 21 CFR 870.5150.
Clinical Applications
- Mechanical thrombectomy for iliofemoral deep vein thrombosis.
- Mechanical thrombectomy for selected upper-extremity deep vein thrombosis.
- Catheter-based removal of peripheral venous thrombus when rapid clot reduction is clinically indicated.
- Use as part of an endovascular treatment strategy that may also include anticoagulation, compression therapy or other medical treatment.
Reported off-label uses
- Mechanical thrombectomy for selected thrombotic occlusions in dialysis grafts or fistulas, depending on the specific device configuration and labeling.
- Use in selected pulmonary embolism procedures with related thrombectomy systems or configurations should not be assumed to be covered by this device's peripheral venous labeling.
Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Evidence Limitations
Practical Considerations
- The system is available in different catheter and sheath configurations; selection depends on vessel diameter, thrombus location and access anatomy.
- The procedure generally requires venous access, fluoroscopic imaging and local anesthesia with moderate sedation or another anesthetic plan selected by the treating team.
- Potential risks include bleeding, vascular injury, venous perforation, embolization, recurrent thrombosis, contrast reaction and complications at the access site.
- MRI safety and conditions depend on the specific ClotTriever components used; the device labeling should be checked before MRI, and implanted or retained components must be identified.
- Contraindications and precautions include unsuitable vessel size or anatomy, inability to obtain safe access, active bleeding or a condition that makes anticoagulation or endovascular treatment unsafe.
