An endoluminal graft repair device includes a multi-lumen catheter (140) with a balloon (142A) coupled to a distal end portion (146) of the catheter (140). A portion of the outer surface of the balloon (142A) is designed and configured to define a repair cavity (148A). A repair cavity lumen (166) of the catheter (140) is coupled to and in fluid communication with the repair cavity (148A). The catheter (140) and balloon (142A) are inserted into an artery system (100), advanced and positioned interluminally through percutaneous procedures so that the repair cavity (148A) is positioned to substantially align with the location of an endoluminal leak in an endoluminal graft used to treat aortic aneurysmal disease. The balloon (142A) is inflated by injecting an inflation fluid through an inflation lumen (166) of the catheter (140) into the balloon to fix the position of the repair cavity (148A) substantially adjacent the location of the endoluminal leak. A repair agent is conveyed to the repair cavity (148A) through the repair cavity lumen (166). The repair agent is conveyed to the repair cavity (148A) through the repair cavity lumen (166). The repair agent is contained by the repair cavity (148A), solidifies in situ, and forms a patch on the endoluminal graft at the location of the endoluminal leak. After removal of the catheter (140), the repair agent patch remains on the endoluminal graft to repair the endoluminal leak. <IMAGE>
