FlowTriever Toolkit
Triever Aspiration Catheter
The Triever Aspiration Catheters feature a highly trackable, large lumen catheter, and large bore syringe designed to rapidly extract large volumes of clot while limiting blood loss.
New T20 Curve
The Triever20 Curve™ is a fully braided large bore catheter with a customizable 260⁰ bend designed for improved navigability & torqueability for challenging anatomies such as the left PA rainbow, TA, IVC and CIT in RA.
Key Features:
- Telescopic Steerability for targeted aspiration: Customizable angled tip for precise catheter placement by telescoping through the Triever24
- 260⁰ directionality range for improved navigation: Increased utility in challenging anatomies (RA, PA, IVC, Renal Veins and upper + lower extremity DVT)
- One Price, One Patient, Many Choices: Triever20 Curve™ is included in the FlowTriever Per Procedure Pricing to use complimentarily with any FlowTriever products.
Triever24 with FLEX Technology
The Triever24 with FLEX technology provides increased flexibility through its softer durometer jacket, featuring a highly trackable, large lumen catheter, and large bore syringe designed to rapidly extract large volumes of clot while limiting blood loss.
Key Features:
- 41% More Flexible than existing Triever24 catheter*
- Superior Trackability to better navigate tortuous anatomies and smoothly deliver the catheter to the left PA and through dilated right hearts
- Effective Aspiration to enhance Whoosh™ technique aspiration for maximum clot removal
No changes to the recommended procedure steps for the improved Triever24 Aspiration Catheter!

*The FlowTriever2 Catheter is not indicated for the treatment of pulmonary embolism
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.
Indications
The FlowTriever System is indicated for the non-surgical removal of emboli and thrombi from blood vessels
Injection, infusion and/or aspiration of contrast media and other fluids into or from a blood vessel
The FlowTriever System is intended for use in the peripheral vasculature and for the treatment of pulmonary embolism.
The Triever Catheters are intended for use in peripheral vasculature and for the treatment of pulmonary embolism
Triever Catheters are also intended for use in treating clot in transit in the right atrium
The FlowTriever2 Catheter is indicated for: the non-surgical removal of emboli and thrombi from peripheral blood vessels. Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel.
The FlowTriever2 Catheter is intended for use in the peripheral vasculature.
The FlowSaver Blood Filter is used with Triever Catheters for autologous blood transfusion.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician
