1. A braid for treating an aneurysm, the braid comprising:
a first radially expandable segment capable of radially expanding to form an outer occlusive sack in the aneurysm configured to seal a neck of the aneurysm as the braid is being moved distally toward the aneurysm;
a second radially expandable segment capable of radially independently expanding inside the outer occlusive sack as the outer occlusive sack is forming to form an inner occlusive sack in the outer occlusive sack as the braid is being moved further distally in the aneurysm;
wherein proximal ends of each segment are aligned with each other and distal ends of each segment are positioned opposite the proximal ends of each segment; and
a plurality of radially flexible elements positioned at the proximal end of the first radially expandable segment, wherein each flexible element is capable of expanding from a collapsed condition to an expanded condition to support a proximal portion of the outer occlusive sack, and wherein each flexible element comprises a radially movable leaf.
