1. A method of filling an aneurysm space within the abdominal aorta, the method comprising:
- placing a prosthesis in the abdominal aorta of a subject;
delivering a fillable bladder in a deflated state into the aneurysm space using a catheter;
placing a filler tube in fluid communication with a single inflow port of the fillable bladder, wherein the filler tube provides access to an interior of the fillable bladder, and wherein the fillable bladder comprises a bladder seal surrounding the fillable bladder, wherein the bladder seal has a first side, a second side, a third side, and a fourth side, wherein a segment of the first side is parallel to a segment of the second side, wherein a segment of the third side is parallel to a segment of the fourth side, and wherein the segment of the first side is perpendicular to the segment of the third side;
filling the fillable bladder with a filling agent through the filler tube until the fillable bladder reaches a desired size in the aneurysm space, wherein the desired size is a size which prevents dislodgment of the prosthesis and allows natural fluid flow through the prosthesis placed in the abdominal aorta and the filling agent comprises at least one of a particulate and a flowable material;
hardening the filling agent;
removing the filler tube from the fillable bladder; and
sealing the port of the fillable bladder.
