Extracting large clots from large vessels without the need for thrombolytics.

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

Mechanically core clot from the vein wall


Capture and Remove large clot burden from big vessels


Treat in a single session

Eliminate the need for thrombolytics

Eliminate ICU Stay

Avoid need for capital equipment

Device Components

ClotTriever Catheter

The ClotTriever Catheter features a nitinol coring element and a braided collection bag, designed to core and collect clot for extraction from ClotTriever Sheath.

ClotTriever Sheath

The ClotTriever® Sheath features a self-expanding nitinol mesh funnel to facilitate clot removal and a large bore sideport for rapid aspiration.


  • The non-surgical removal of thrombi and emboli from blood vessels.
  • Injection, infusion and/or aspiration of contrast media and other fluids into or from a blood vessel.

The ClotTriever Thrombectomy System is intended for use in the peripheral vasculature including deep vein thrombosis (DVT).

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