The method involves placing a prosthesis in the abdominal aorta; delivering a fillable bladder in a deflated state into the aneurysm space using a catheter; placing a filler tube in fluid communication with an inflow port of the fillable bladder. The fillable bladder comprises a bladder seal surrounding the fillable bladder and the bladder seal has a first side, a second side, a third side, and a fourth side. The first side is symmetric with the second side with respect to a first axis of the fillable bladder and the third side is symmetric with the fourth side with respect to a second axis of the fillable bladder. The first axis is perpendicular to the second axis. The method further involves filling the fillable bladder with a filling agent and removing the filler tube. ## Claims ### Claim 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 an inflow port of the fillable bladder, wherein the filler tube accesses 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; and 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the first side has a first side length, the second side has a second side length, the third side has a third side length, and the fourth side has a fourth side length, wherein the first side length is equal to the second side length, and wherein the third side length is equal to the fourth side length. ### Claim 3 (depends on 1) The method of claim 1, wherein the first side is symmetric with the second side with respect to a first axis of the fillable bladder and the third side is symmetric with the fourth side with respect to a second axis of the fillable bladder, wherein the first axis is perpendicular to the second axis. ### Claim 4 (depends on 1) The method of claim 1, further comprising hardening the filling agent. ### Claim 5 (depends on 1) The method of claim 1, further comprising sealing the inflow port of the fillable bladder. ### Claim 6 (depends on 1) The method of claim 1, further comprising removing the filler tube from the fillable bladder. ### Claim 7 (depends on 1) The method of claim 1, further comprising imaging the aneurysm space, and then filling the fillable bladder according to the imaging of the aneurysm space. ### Claim 8 (depends on 1) The method of claim 1, wherein at least one of the fillable bladder and the filling agent is made of a bioabsorbable material. ### Claim 9 A method of filling an aneurysm space within the abdominal aorta, the method comprising: delivering a fillable bladder in a deflated state into the aneurysm space using a catheter; placing a filler tube in fluid communication with an 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; and 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. ### Claim 10 (depends on 9) The method of claim 9, further comprising removing the filler tube from the fillable bladder. ### Claim 11 (depends on 9) The method of claim 9, wherein the first side has a first side length, the second side has a second side length, the third side has a third side length, and the fourth side has a fourth side length, wherein the first side length is equal to the second side length, and wherein the third side length is equal to the fourth side length. ### Claim 12 (depends on 9) The method of claim 9, further comprising hardening the filling agent. ### Claim 13 (depends on 9) The method of claim 9, further comprising sealing the inflow port of the fillable bladder. ### Claim 14 (depends on 9) The method of claim 9, further comprising imaging the aneurysm space, and then filling the fillable bladder according to the imaging of the aneurysm space. ### Claim 15 (depends on 9) The method of claim 9, wherein at least one of the fillable bladder and the filling agent is made of a bioabsorbable material. ### Claim 16 (depends on 9) The method of claim 9, wherein the catheter is an over-the-wire catheter.
