The First and Only Mechanical Thrombectomy Device Indicated for Pulmonary Embolism.

The FlowTriever is an over-the-wire system designed to:

Remove clot through both mechanical and aspiration mechanisms of action


Capture and Remove large clot burden from big vessels


Treat in a single session

Eliminate the need for thrombolytics

Eliminate ICU Stay

Device Components


The Triever20 features a highly trackable, large lumen catheter, and large bore syringe designed to rapidly extract large volumes of clot while limiting blood loss.


FlowTriever Catheter

The FlowTriever Catheter features three self-expanding nitinol mesh disks that are designed to engage, disrupt, and deliver clot to the Triever20 for extraction.


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.

Caution: Federal (USA) law restricts this device to sale by or on the order of a physician
