Blood Return System

Enabling Bloodless Thrombectomy for Pulmonary Embolism 

The FlowSaver™ is designed to be used with the FlowTriever System to reduce blood loss by filtering aspirated thrombi and blood for reinfusion back to the patient, thus enabling bloodless thrombectomy for pulmonary embolism (PE) procedures. 

The FlowSaver is compatible with Triever Catheters and includes a 40 micron filtration system, a clot reservoir, and a 60cc collection syringe. The accessible filtration design allows for clot examination and reservoir cleaning for more filtrations. Filtered blood can be reintroduced using a standard luer lock with the 60cc collection syringe.

Focus on clot extractions and patient outcomes without worrying about blood loss

Re-infuse filtered blood with negligible hemolysis*


Reduce the need for blood transfusions or a perfusionist
