摘要：
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 have an external nitinol tube surrounding platinum concentrically disposed within the external nitinol tube. The composite filaments may have a diameter of between 0.00075″ and 0.00125″.
