The ClotTriever Thrombectomy System received FDA clearance through the 510(k) pathway on August 29, 2019. It is manufactured by Inari Medical and is classified as a Class 2 device.
What It Is
The ClotTriever Thrombectomy System is a mechanical thrombectomy device designed to remove thrombi from large veins. It is intended for use in patients with venous thromboembolism, providing an alternative to anticoagulation therapy.
Clinical Applications
The device is commonly used in clinical scenarios involving deep vein thrombosis (DVT) of the upper extremities and iliofemoral region. It is particularly useful in cases where rapid clot removal is necessary to alleviate symptoms and prevent complications.
Evidence Summary
The available literature includes 13 studies, comprising randomized controlled trials, case series, and retrospective analyses, conducted between 2023 and 2025. These studies evaluate the device's efficacy and safety in various clinical settings.
Reported Outcomes
Published studies report that the ClotTriever Thrombectomy System effectively reduces thrombus burden in patients with upper extremity and iliofemoral DVT. Clinical outcomes include improved Villalta scores and reduced incidence of post-thrombotic syndrome. Technical success rates are high, with significant symptom relief reported in treated patients.
Safety Profile
Reported complications include access site adverse events, particularly when accessing small upper extremity veins. Other potential complications involve device-related issues during thrombectomy procedures, although these are relatively infrequent.
Evidence Limitations
Current evidence is limited by the small sample sizes and the lack of long-term follow-up data in some studies. Further research is needed to establish the long-term safety and efficacy of the device across diverse patient populations.
