1. An aneurysm occlusion device, comprising:
a mesh comprising inner and outer layers and configured to compress for delivery through a catheter and expand upon release from the constraint of the catheter into an expanded configuration for positioning within an aneurysm, wherein the inner and outer layers meet distally at a fold and proximally at a hub, and
wherein, in the expanded configuration and when positioned within the aneurysm, the mesh comprises a proximal region configured to be disposed over a neck of the aneurysm, a distal region configured to be within the aneurysm cavity, and a lateral region between the proximal and distal regions that is configured to press outwardly on the aneurysm wall, wherein the lateral region comprises a portion of a central region of the aneurysm occlusion device, and
wherein the inner and outer layers contact one another along the proximal and lateral regions of the mesh, and
wherein the inner and outer layers conform to one another along the proximal and lateral regions and have different shapes along the distal region.
