Abstract
The endovascular graft includes a dual chamber cuff structure. The endovascular graft includes a tubular structure having a first end and a second end. The tubular structure has a wall defining a lumen between the first and second ends. The endovascular graft includes a cuff circumferentially secured to the tubular structure. The cuff has an interior cavity which is bifurcated such that the interior cavity includes a circumferential outer chamber and a circumferential inner chamber. The method for forming the endovascular graft includes inserting an expansion substance into the inner chamber to resist a luminal intrusion of the tubular structure resulting from the insertion of the expansion substance into the outer chamber. The expansion substance within the outer chamber is stiffened. The expansion substance within the inner chamber is removed.
