Abstract: A system and method for managing an occlusion, such as a blood clot, within a lumen or passageway of a patient. More particularly, a system and method for rapidly restoring blood flow through an occlusion including a self-expanding, tubular member through which blood may flow when in an expanded state. The tubular member has a structure configured to engage the occlusive material, thereby allowing for extraction of at least a portion of the occlusive material. The system may further employ a material extraction member that is deployed distally of the tubular member.

Abstract: Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include: providing a thrombus extraction device including a proximal self-expanding member formed of a fenestrated structure, a substantially cylindrical portion formed of a net-like filament mesh structure having a proximal end coupled to a distal end of the fenestrated structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction device by stacking a portion of the net-like filament mesh structure outside of the catheter by distally advancing the self-expanding member until the self-expanding member is beyond a distal end of the catheter; retracting the self-expanding member to unstack the portion of the net-like filament mesh structure and to capture the portion of the thrombus; and withdrawing the thrombus extraction device from the body.

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.
