摘要： Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a resilient self-expanding permeable implant having a radially constrained elongated state configured for delivery within a catheter lumen and an expanded state with a longitudinally shortened configuration, and a plurality of elongate filaments which are woven together. Each of the plurality of elongate filaments may have a diameter between about 0.0005 and about 0.005 inches. The implant includes at least some filaments consisting of nitinol and at least some composite filaments that are drawn filled tube wires comprising an external nitinol tube and a highly radiopaque material concentrically disposed within the external tube. The implant has at least about 40% composite filaments relative to a total number of filaments, and wherein a total number of filaments is about 10 to about 300.

摘要： Methods and devices for treating a cerebral aneurysm are described. The device may include a self-expanding resilient permeable shell made from elongate resilient filaments. At least some of the filaments have a distal region that extends beyond the distal end of the permeable shell and form an extension having a generally circular shape when expanded. The permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with a globular, axially shortened configuration. The permeable shell has a plurality of openings formed between the braided filaments. The distal regions of the plurality of filaments that form the extension may be braided, partially braided, or unraveled. Once deployed within the cerebral aneurysm, the extension is positioned near a dome of the cerebral aneurysm.

摘要： 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.
