摘要： A device for treatment of a vascular defect within a patient's vasculature includes a self-expanding permeable shell having a proximal end, a distal end, and a longitudinal axis, the shell comprising a plurality of elongate resilient filaments having a braided structure, wherein the filaments are secured at at least one of the proximal end or the distal end of the permeable shell, wherein the permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with an axially shortened configuration relative to the radially constrained state, the permeable shell having a plurality of openings formed between the braided filaments, wherein the permeable shell in its expanded state comprises a plurality of circumferentially-arrayed lobes.

摘要： Devices and methods for treatment of a patient's vasculature may include a resilient self-expanding permeable implant having a plurality of elongate filaments secured in a hub at a proximal end of the permeable implant. Each of the plurality of elongate filaments may have a diameter between about 0.0005 and about 0.005 inches. The implant includes at least some filaments consisting of nitinol and at least some composite filaments that are drawn filled tube wires comprising an external nitinol tube and a radiopaque material concentrically disposed within the external tube. The implant has at least about 40% composite filaments relative to a total number of filaments, and wherein a total number of filaments is about 10 to about 300.
