Abstract
Devices and methods for treatment of a patient's vasculature with some embodiments configured for delivery with a microcatheter for treatment of the cerebral vasculature of a patient. 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 Some embodiments may include at least about 40% composite filaments having a high strength material and a highly radiopaque material. In some embodiments, the total cross sectional area of the highly radiopaque material is between about 11% and about 30% of the total cross sectional area of the plurality of elongate elements.
