Abstract: Devices and methods for treatment of a patient's vasculature are described. Embodiments may include an implant having multiple mesh layers. A first and second layer of the implant may be formed by folding over a single mesh and the third layer may be formed from a different mesh. The first, second, and third layers may be either a stasis or a structural layer and may be arranged in different orders. Embodiments may also include structures to assist in the expansion of the device. These structures may include an expandable loop or reinforcing finger extensions. Embodiments may also include a corrugation or ridge around a middle section of the implant to assist in deployment.

Abstract: Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a first permeable shell and a second permeable shell, where the second permeable shell sits within an interior cavity of the first permeable shell. The first and second permeable shells may each be made from a plurality of elongate filaments that are woven together to form a mesh. The mesh of the first permeable shell may have a larger mesh density and be softer than the mesh of the second permeable shell.

Abstract: Devices and methods for treatment of a patient’s vasculature are described. Embodiments may include a permeable implant 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 implant may include a cavity in a proximal section that may optionally house embolic material, such as coils. Alternatively, the implant may have an expanded preset shape that is different than an expanded preset shape that is assumed after deployment in an aneurysm. The expanded preset shape may be frustoconical. Alternatively, the implant may include an outer skirt coupled to a proximal section of the permeable implant.
