Abstract
Devices for treatment of a cerebral aneurysm are described. Embodiments may include a self-expanding 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 that are woven together, which define a cavity of the permeable shell. The permeable shell includes 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. The composite filaments may have a diameter of 0.00075″, 0.001″, 0.0015″, and/or 0.00125″.
