Abstract
Methods for treatment of a cerebral aneurysm are described. Methods include providing 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 may have a diameter of 0.00075″, 0.001″, 0.0015″, and/or 0.00125″. The permeable shell is advanced in the constrained state within a catheter. The permeable shell is then deploying the permeable shell within the cerebral aneurysm, wherein the permeable shell expands to the expanded state within the cerebral aneurysm. The catheter is then withdrawn after deploying the permeable shell.
