Abstract
Systems and methods for treating thrombosis and or emboli in a peripheral vasculature of a patient are disclosed herein. The method can include providing a thrombus extraction device including a proximal self-expanding coring portion formed of a unitary fenestrated structure and a distal expandable tubular portion formed of a braided filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus in a vessel; deploying the thrombus extraction device from the catheter from a constrained configuration to an expanded configuration; retracting the thrombus extraction device proximally so that the coring portion cores and separates a portion of the vascular thrombus from the venous vessel wall while the mesh structure captures the vascular thrombus portion; and withdrawing the thrombus extraction device from the patient to remove the vascular thrombus portion from the vessel.
