Summary: The ClotTriever XL Catheter is a medical device used for mechanical thrombectomy in venous systems. It is primarily used by interventional radiologists and vascular surgeons to remove large clots from veins.
FDA Clearance Information
Pathway 510K
Number K223210 ↗
Decision Date April 27, 2023
Product Code QEW
Device Class Class 2
Evidence 23 studies
The ClotTriever XL Catheter by Inari Medical was cleared via the FDA 510(k) pathway on April 27, 2023. It is a Class 2 device under product code QEW.
What It Is
The ClotTriever XL Catheter is a specialized catheter designed for the removal of thrombi from large veins. It operates by mechanically capturing and extracting clots without the need for thrombolytic drugs, reducing the risk of bleeding complications. The device is engineered to accommodate larger clot burdens, making it suitable for extensive thrombotic events.
Clinical Applications
This device is commonly used in the treatment of deep vein thrombosis (DVT) in the iliac, femoral, and other large veins. It is typically utilized in hospital settings by interventional radiologists and vascular surgeons. The ClotTriever XL is particularly beneficial for patients who are at high risk for bleeding or have contraindications to thrombolytic therapy.
Indications for Use
The ClotTriever XL Catheter is indicated for patients with venous thromboembolism, particularly those with large clots in major veins. It is designed to safely and effectively remove thrombi, improving blood flow and reducing the risk of complications.
Practical Considerations
The ClotTriever XL Catheter is available in various sizes to accommodate different patient anatomies and clot sizes. It is compatible with standard vascular access techniques and requires fluoroscopic guidance for accurate placement. Clinicians should be trained in mechanical thrombectomy procedures to ensure optimal outcomes.
