Full Study Name

FlowTriever Pulmonary Embolectomy Clinical Study (IRB no. 43583)


This study focuses on individuals diagnosed with a pulmonary embolism (blood clot) that is trapped within the lungs. The purpose of the study is to evaluate the safety and effectiveness of the FlowTriever Aspiration System (referred to as “FlowTriever System”) for removing blood clots from pulmonary arteries (vessels that transport blood from the heart to the lungs). The FlowTriever System is a medical device that is used to trap the clot and pull it into a thin tube (catheter) so that the clot can be removed from the body. The device has been approved by the U.S. Food and Drug Administration for removing emboli and thrombi (blood clots) from blood vessels, but its use in this study is investigational.
