A braided implant is provided that can secure within an aneurysm sac, occlude a majority of the aneurysm's neck, and at least partially fill the aneurysm sac. The implant can include a tubular braid that can be set into a predetermined shape, compressed for delivery through a microcatheter, and implanted in at least one implanted position. In some examples, the tubular braid can be implanted in two distinct implanted shapes, allowing for treatment of a wide range of aneurysm sizes. In some examples, the implanted braid can include a compaction resistant column spanning the height of the aneurysm.
