flowtriever retrieval aspiration system

Inari Medical

Summary: The FlowTriever Retrieval Aspiration System is a device used for mechanical thrombectomy in patients with pulmonary embolism. It is typically used by interventional radiologists or cardiologists in hospital settings.

FDA Clearance Information

Pathway 510K
Decision Date December 17, 2018
Product Code QEW
Device Class Class 2
Evidence 14 studies

The FlowTriever Retrieval Aspiration System by Inari Medical was cleared via the FDA 510(k) pathway on December 17, 2018. It is a Class 2 medical device.

What It Is

The FlowTriever Retrieval Aspiration System is a mechanical thrombectomy device designed to remove blood clots from the pulmonary arteries. It uses a large-bore catheter to aspirate clots, providing a minimally invasive option for treating pulmonary embolism. This device allows for rapid clot removal without the need for thrombolytic drugs, reducing the risk of bleeding complications.

Clinical Applications

The device is commonly used in the treatment of intermediate- to high-risk pulmonary embolism, where rapid clot removal is crucial. It is typically employed in hospital settings, particularly in interventional radiology or cardiology departments. The system is suitable for patients who are at risk of complications from thrombolytic therapy or when immediate clot removal is necessary.

Indications for Use

The FDA has cleared the FlowTriever System for use in patients with pulmonary embolism, specifically those who have a significant clot burden that requires mechanical intervention. It is intended for patients who are at intermediate to high risk and need rapid intervention.

Practical Considerations

The FlowTriever System is available in various sizes to accommodate different patient anatomies. It is compatible with standard catheterization lab equipment. Clinicians should be trained in large-bore catheter techniques and be aware of potential complications such as vascular injury.

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 is effective in reducing clot burden, this case highlights the potential for serious complications. The study suggests careful patient selection and monitoring during the procedure. Limitations include its focus on a single case, which may not represent typical outcomes.
