Filamentary devices for treatment of vascular defects

A method for treating a patient's vasculature, comprising the steps of:

• advancing a resilient self-expanding permeable implant coupled to a pusher within a catheter to a region of interest within the patient's vasculature,
• wherein the permeable implant comprises a plurality of elongate filaments secured in a hub at a proximal end of the permeable implant, wherein each of the plurality of elongate filaments has a diameter between about 0.0005 inches to about 0.005 inches, wherein the permeable implant comprises at least some filaments consisting of nitinol and at least some composite filaments, the composite filaments comprising drawn filled tube wires each comprising an external nitinol tube and a radiopaque material concentrically disposed within the external tube, and wherein the permeable implant has at least about 40% composite filaments relative to a total number of filaments, wherein a total number of filaments is about 10 to about 300;
• deploying the permeable implant in the region of interest, wherein the permeable implant expands to an expanded state;
• and
• detaching the permeable implant from the pusher.
