The present invention provides a braided implant with a retractable dual proximal layer and methods for administering the braided implant to treat aneurysms. 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 that is based on the predetermined shape and the geometry of the aneurysm in which the braid is implanted. The implant can also have a retractable ball segment at the proximal end of the device made of the same braid that can be heat treated into an ellipsoid shape. The retractable ball segment can be movable from a position outside the aneurysm to a position at least partially enclosed within the implant to increase or decrease the height of the implant relative to the aneurysm or better conform the implant to the neck of the aneurysm.
