摘要： Systems for removal of thrombus from a blood vessel in a body of a patient are disclosed. The system can include: a thrombus extraction device including a proximal selfexpanding coring element; a distal expandable element formed of a mesh structure having a proximal end portion attached to a distal end portion of the coring element; a catheter defining a lumen configured to constrain the thrombus extraction device; an intermediate shaft coupled to a proximal end portion of the coring element; an inner shaft coupled to a distal end portion of the expandable element and slidably displaceable relative to the intermediate shaft to control expansion of the expandable element; and an introducer sheath assembly including an elongate sheath defining an insertion lumen; an expandable funnel coupled to a distal end portion of the elongate sheath; and an elongate obturator including a capture feature configured to retain the funnel in a constrained configuration. In addition, an introducer sheath assembly is also disclosed herein.

摘要： 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 unitary fenestrated structure, a distal substantially cylindrical portion formed of a net-like filament mesh structure, and an inner shaft member connected to a distal end of the net-like filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction; retracting the thrombus extraction device to separate a portion of the thrombus from the vessel wall and to capture the portion of the thrombus within the net-like filament mesh structure; and withdrawing the thrombus extraction device from the body to remove thrombus from the patient.
