Abstract
Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a permeable implant such as a permeable shell or mesh having a radially constrained state configured for delivery within a catheter lumen, an expanded state, and a plurality of elongate filaments that are woven together. The permeable implant may include a stiffer proximal portion that is configured to sit at the neck of an aneurysm. The stiffer proximal portion may include additional mesh layers on either the inside or the outside of a first permeable shell. The distal portion of the device may be softer and deformable.
