Abstract
Methods for treatment of a cerebral aneurysm are described. Embodiments may include a self-expanding resilient permeable shell having a radially constrained elongated state configured for delivery within a catheter lumen, an expanded state with a globular and longitudinally shortened configuration relative to the radially constrained state, and a plurality of elongate filaments which are woven together, which define a cavity of the permeable shell. The permeable shell includes at least some filaments consisting of nitinol and at least some composite filaments. The composite filaments include drawn filled tube wires having an external nitinol tube and a highly radiopaque material concentrically disposed within the external tube.
