1. A method for treatment of an aneurysm, comprising:

  • positioning a distal opening of a catheter adjacent to the aneurysm, the catheter containing a framing device comprising a braided structure having a compressed state for delivery through the catheter to the aneurysm and an expanded state, the braided structure being shape set such that it forms a preset shape in the expanded state that has an interior cavity and an exterior surface for contacting a wall of the aneurysm;

    releasing the framing device from the catheter such that the braided structure self-expands to its preset shape and the exterior surface of the braided structure contacts a distal portion of the aneurysm wall; and

    after self-expansion of the braided structure, releasing at least one expandable component comprising foam into the interior cavity of the braided structure and thereby further expanding the framing device such that a distal portion of the framing device conforms at least partially to a shape of at least the distal portion of the aneurysm wall.
