1. An apparatus for treating an aneurysm in a blood vessel, comprising:
an occlusion device configured to be releasably coupled to an elongate delivery shaft, the occlusion device comprising:
a cover having a proximal end and a distal end and comprising a mesh tube that is inverted on itself, the mesh tube having a proximal end and a distal end, wherein the proximal end and the distal end of the mesh tube are at or adjacent the proximal end of the cover, the cover having a maximum outer diameter located between the distal end of the cover and the proximal end of the cover, wherein the cover increases in diameter from the proximal end of the cover to the maximum outer diameter, and wherein the cover decreases in diameter from the maximum outer diameter to the distal end of the cover, and wherein the inversion of the mesh tube begins at the distal end of the cover, the inversion providing an outer layer, an inner layer, and a distal opening; and
a first tubular mesh comprising a first end, a second end, and a looped shape having an apex, wherein the first end and the second end of the first tubular mesh are secured within an interior of the cover, and wherein the apex of the looped shape of the first tubular mesh extends distally out of the distal opening of the cover.
