    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 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.

    Abstract: A device and method for intravascular treatment of an embolism, and particularly a pulmonary embolism, is disclosed herein. One aspect of the present technology, for example, is directed toward a clot treatment device that includes a support member having a plurality of first clot engagement members and second clot engagement members positioned about the circumference of a distal portion of the support member. In an undeployed state, individual first clot engagement members can be linear and have a first length, and individual second clot engagement members can be linear and have a second length that is less than the first length. The clot engagement members can be configured to penetrate clot material along an arcuate path and hold clot material to the clot treatment device.

    Abstract: Catheter shafts and associated devices, systems, and methods are disclosed herein, A representative catheter in accordance with an embodiment of the disclosure includes a generally tubular outer structure and an inner structure surrounded by the outer structure. The inner structure surrounds a catheter lumen. The inner structure includes over-lapping edges such that, when the catheter is bent along its longitudinal axis, the over-lapping edges move relative to one another.

    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.
