FDA Clearance Information

Pathway 510K
Decision Date February 23, 2021
Product Code QEW
Device Class Class 2
Evidence 23 studies

The ClotTriever Thrombectomy System was cleared by the FDA via the 510(k) pathway on February 23, 2021. It is manufactured by Irani Medical and classified as a Class 2 device.

What It Is

The ClotTriever Thrombectomy System is a mechanical thrombectomy device designed for the removal of thrombi from the venous system. It is intended for use in patients with venous thromboembolism, providing a minimally invasive option for clot extraction.

Clinical Applications

Common clinical scenarios for the ClotTriever include treatment of upper extremity deep vein thrombosis and iliofemoral deep vein thrombosis. It is particularly useful in cases where anticoagulation therapy is insufficient or contraindicated.

Evidence Summary

The available literature includes 13 studies, comprising randomized controlled trials, case series, and retrospective analyses, published between 2023 and 2025. These studies evaluate the device's efficacy and safety in various venous thrombosis contexts.

Reported Outcomes

Published studies report that the ClotTriever Thrombectomy System is effective in removing thrombi from the venous system, with significant improvements in symptoms and reduction in thrombus burden. In one study, the device showed comparable efficacy to anticoagulation in iliofemoral DVT treatment.

Safety Profile

Reported complications include access site adverse events, particularly when using small upper extremity veins. Other studies highlight the importance of proximal IVCF protection during procedures to prevent complications.

Evidence Limitations

Current evidence is limited by small sample sizes and a lack of long-term follow-up data. Further research is needed to establish the device's efficacy across diverse patient populations and to evaluate long-term outcomes.
