    摘要: Neurovascular flow diverter and delivery systems, and methods of using the same are disclosed herein. The systems can include an introducer sheath, a catheter, a deployable flow diverter that can be contained in the introducer sheath or in the catheter, a core wire, and one or several deployment features coupled to the core wire and engaging the flow diverter. The deployment features can include one or more of a pusher, one or several friction bumps, one or several deployment coils, a claw mechanism, a self-expanding element, a supporting coil, a tip coil, and/or an atraumatic tip. One or more of the deployment features can be radiopaque.

    摘要: Disclosed is a false lumen closure assembly for closing a false lumen in a body vessel including a compressed false lumen occluder, a carrier catheter and a retractable sheath. The compressed false lumen occluder includes a stent graft including at least one occlusive barrier across the stent graft to occlude blood flow through an interior of the stent graft. The carrier catheter carries the false lumen occluder and extends from a proximal end proximal of the false lumen occluder to a distal end distal of the false lumen occluder, and passes the false lumen occluder exteriorly of the stent graft. The compressed false lumen occluder and at least part of the carrier catheter are disposed in a lumen of the retractable sheath.

    摘要: A flow diverter device for restricting blood flow to an aneurysm at a blood vessel bifurcation is disclosed and described. The flow diverter device includes a linear device body that includes a high-density distal cap having an outer convex shape structurally configured to engage an aneurysm ostium on a blood vessel side at a blood vessel bifurcation, such that the high-density distal cap restricts blood flow into the aneurysm from the blood vessel bifurcation, a low-density section adjacent the high-density distal cap to allow blood flow through the blood vessel bifurcation, a stent section adjacent the low-density section and structurally configured to stabilize the linear device body in a lumen of the blood vessel bifurcation, and a proximal wire attachment at a lateral edge of the stent section, where the stent section terminally couples to a distal end of the proximal wire attachment.

    摘要: A device for temporarily protecting a neck of an aneurysm of a blood vessel is provided. The device includes a plurality of wires coiled to form a collapsible frame configured to expand and substantially conform to a shape of an inside surface of the blood vessel while the aneurysm is being treated. The device includes a retention wire disposed at a proximal end of the frame of the plurality of wires. The device includes a cover comprising at least a first portion configured to be disposed directly against a neck of the aneurysm while the aneurysm is being treated, the first portion having a first porosity to blood flow. Related methods of use and manufacturing are also provided.
