flowtriever retrieval aspiration system

Inari Medical

Summary: The FlowTriever Retrieval Aspiration System is a medical device used for mechanical thrombectomy in patients with pulmonary embolism. It is typically used by interventional radiologists and cardiologists to remove blood clots from the pulmonary arteries.

FDA Clearance Information

Pathway 510K
Decision Date December 18, 2020
Product Code QEW
Device Class Class 2
Evidence 14 studies

The FlowTriever Retrieval Aspiration System by Inari Medical was cleared through the FDA 510(k) pathway on December 18, 2020. It is a Class 2 medical device under product code QEW.

What It Is

The FlowTriever Retrieval Aspiration System is a catheter-based device designed to remove blood clots from the pulmonary arteries. It combines mechanical thrombectomy with aspiration to effectively reduce clot burden in patients with pulmonary embolism. The system is minimally invasive and allows for percutaneous access, making it a valuable tool in acute settings.

Clinical Applications

This device is commonly used in the treatment of intermediate- to high-risk pulmonary embolism, particularly in patients who may not be candidates for thrombolytic therapy. It is typically employed in hospital settings by interventional radiologists and cardiologists. The device is used in catheterization labs where rapid intervention can significantly improve patient outcomes.

Indications for Use

The FlowTriever system is indicated for use in patients with pulmonary embolism, specifically those who have large clots obstructing blood flow in the pulmonary arteries. It is intended for patients who require mechanical intervention to restore normal circulation.

Practical Considerations

The device is available in various sizes to accommodate different patient anatomies and is compatible with standard catheterization lab equipment. Clinicians should be trained in percutaneous techniques and be familiar with the device's operation to ensure optimal outcomes.

Related Literature

The linked study discusses a case of cardiac tamponade following the use of the FlowTriever system for percutaneous pulmonary embolectomy. While the device effectively reduced clot burden, the study highlights a potential complication, emphasizing the need for careful patient monitoring. The study is limited by its focus on a single case, and further research is needed to assess the incidence of such complications.
