The implant can be closed at one or more of the braid ends to define a substantially enclosed bowl-shaped volume. ## Claims ### Claim 1 A device for occluding an aneurysm comprising: an implant movable from a collapsed state to a deployed state, the implant comprising a proximal end, a distal end, and a braided segment forming a substantially continuous braided structure between the proximal end and the distal end, wherein in the deployed state, the implant comprises: an outer occlusive sack extending from the proximal end of the implant and capable of occluding an aneurysm neck; an inner occlusive sack extending form the distal end of the implant and forming a trough within the outer occlusive sack; and a fold in the braided segment positioned between the outer occlusive sack and the inner occlusive sack, wherein the implant is capable of anchoring within the aneurysm such that a majority of a sac of the aneurysm is unoccupied by a substantially enclosed volume defined by the implant in the deployed state between the outer occlusive sack and the inner occlusive sack, wherein the braided segment comprises a memory shape material, the braided segment comprising a first, predetermined shape and a second, deformed shape, wherein the braided segment is in the second, deformed shape when the implant is in the collapsed state, and wherein the braided segment moves to a third, deployed shape when the implant is in the deployed state, the third, deployed shape based at least in part on the predetermined shape and a curvature of an aneurysm wall, wherein, in the first, predetermined shape, the fold defines an annular ridge, wherein the implant further comprising a radiopaque marker band encircling the distal end of the implant, and wherein, in the first, predetermined shape, the radiopaque marker band extends approximate a plane defined by the annular ridge. ### Claim 2 (depends on 1) The device of claim 1 wherein a first portion of the braided segment is capable of self-expanding to form the outer occlusive sack and a second portion of the braided segment is capable of self-inverting to form the inner occlusive sack. ### Claim 3 (depends on 1) The device of claim 1 wherein in the collapsed state, the implant is sized to be delivered to the aneurysm through a microcatheter. ### Claim 4 (depends on 1) The device of claim 1 wherein one or more of the proximal end of the implant or the distal end of the implant is closed. ### Claim 5 (depends on 4) The device of claim 4 wherein one or more of the distal end or the proximal end is closed by one of a band, an end cap, or heat set. ### Claim 6 (depends on 1) The device of claim 1 wherein in the deployed state, the outer occlusive sack is capable of sealing the aneurysm neck to at least one of deflect, divert, and slow a flow into the aneurysm. ### Claim 7 (depends on 1) The device of claim 1 wherein in the deployed state, the distal end and proximal end of the implant are each positioned along an axis approximately perpendicular to a plane defined by the aneurysm neck and approximate a center of the aneurysm neck. ### Claim 8 (depends on 1) The device of claim 1 wherein the implant is implantable in an aneurysm adjacent bifurcated blood vessel branches, and wherein the implant is deliverable to the aneurysm through a stem branch feeding the bifurcated blood vessel branches. ### Claim 9 (depends on 1) The device of claim 1 wherein, in the predetermined shape, the braided segment comprises an annular ridge defined by the fold that is larger circumferentially than a maximum circumference of the aneurysm sac. ### Claim 10 (depends on 1) The device of claim 1 wherein, in the first, predetermined shape, the inner occlusive sack substantially conforms to the outer occlusive sack. ### Claim 11 An implant for treating an aneurysm comprising a braided mesh, wherein the braided mesh is movable to an implanted configuration, the braided mesh comprising a substantially contiguous surface defining a substantially enclosed, bowl-shaped volume in the implanted configuration, and wherein the implant is capable of anchoring within the aneurysm such that a majority of a sac of the aneurysm is unoccupied by the bowl-shaped volume, wherein the braided mesh comprises a memory shape material, the braided mesh comprising a first, predetermined shape and a second, deformed shape, wherein the braided mesh is in the second, deformed shape is sized to traverse vasculature, wherein the braided mesh moves to a third, deployed shape when the implant is in a deployed state, the third, deployed shape based at least in part on the predetermined shape and a curvature of an aneurysm wall, wherein the implant further comprising a radiopaque marker band encircling a distal end of the implant within a trough of the bowl-shaped volume, and wherein, in the first, predetermined shape, the radiopaque marker band extends approximate a plane defined by an annular ridge of the bowl-shaped volume. ### Claim 12 (depends on 11) The implant of claim 11 wherein the braided mesh is movable from a substantially tubular configuration having a first end and a second end to the implanted configuration, and wherein, in the implanted configuration, the first end and the second end are each positioned approximate a center of the bowl-shaped volume and a fold in the braided mesh defines an annular ridge of the bowl-shaped volume. ### Claim 13 (depends on 11) The implant of claim 11, wherein the braided mesh comprises a memory shape material, the braided mesh comprising a first, predetermined shape and a second, deformed shape, wherein the braided mesh is in the second, deformed shape is sized to traverse vasculature, wherein the braided mesh moves to a third, deployed shape when the implant is in the deployed state, the third, deployed shape based at least in part on the predetermined shape and a curvature of an aneurysm wall, wherein, in the first, predetermined shape, an annular ridge of the bowl-shaped volume that is larger circumferentially than a maximum circumference of the aneurysm sac. ### Claim 14 (depends on 11) The implant of claim 11, wherein the braided mesh comprises a memory shape material, the braided mesh comprising a first, predetermined shape and a second, deformed shape, wherein the braided mesh is in the second, deformed shape is sized to traverse vasculature, wherein the braided mesh moves to a third, deployed shape when the implant is in the deployed state, the third, deployed shape based at least in part on the predetermined shape and a curvature of an aneurysm wall, and wherein, in the first, predetermined shape, an inner occlusive sack of the bowl-shaped volume substantially conforms to an outer occlusive sack of the bowl-shaped volume and a fold separating the inner occlusive sack and outer occlusive sack defines an annular ridge of the bowl-shaped volume.
