1. A method for treatment of an aneurysm, the method comprising:
acquiring a first image visualizing:
an occlusive member positioned within the aneurysm, the occlusive member including a first radiopaque marker and substantially filling a volume of the aneurysm; and
a conduit having a distal portion positioned within the aneurysm, the distal portion of the conduit including a second radiopaque marker; and
deforming the occlusive member so that the occlusive member collapses on itself by delivering an embolic element between the occlusive member and a dome of the aneurysm via the conduit; and
acquiring a second image in which the first radiopaque marker is further from the second radiopaque marker than in the first image, indicating collapse of the occlusive member.
