    摘要： Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.

    摘要： Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, is directed toward an occlusion device that includes a proximal portion, a distal portion, and an intermediate portion extending between the proximal portion and the distal portion. The distal portion can include a directing region and a lead-in member that extends distally from the directing region. When the occlusion device is in a deployed configuration, the intermediate portion can form a preset bend in the occlusion device that positions the directing region at an angle with respect to the proximal portion. As a result, as the occlusion device is pushed distally out of a delivery catheter into the aneurysm, the directing region directs the distal portion away from exiting the aneurysm through the neck such that the proximal portion crosses the neck and generally remains within the aneurysm.

    摘要： Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, is directed toward an occlusive device that includes a first mesh having an expanded state in which it curves about a first axis to form a first band, and a second mesh having an expanded state in which it curves about a second axis different than the first axis to form a second band. The second band may be positioned radially inward of the first band such that the device includes first and second overlap regions in which the first band overlaps the second band.
