摘要: An intracorporeal device, such as an endovascular graft, having a tubular section with circumferential or helical radial support members. The radial support members may be inflatable channels which support the tubular structure of the graft and which are appropriately sized and longitudinally spaced to prevent or reduce kinking of the tubular structure upon bending of the tubular structure.

摘要: An aircraft fuel tank construction for providing enhanced fuel tank survivability and aircraft structural integrity when the fuel tank is penetrated by an exploding projectile, utilizes selective placement of low density, fluid-displacing material to create a low shock impedance region which decouples protected fuel tank structure from the destructive effects of a shock wave. The low shock impedance region may be formed using closed cell foam, or using isolators comprising bladders inflated with a compressible, inert gas. Such bladders should have a wedge shape and a wedge angle of at least 15 degrees. Precise shape is less important with closed cell foam. Polymethylacrilimide has been shown to be particularly effective for this purpose. Finite element analysis is useful in tuning the design of actual low shock impedance regions for actual aircraft designs. This construction is especially useful in fuel tanks manufactured from composite materials where tank wall pull-off from internal spars and stiffeners is the primary mode of catastrophic structural failure.

摘要: 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.

摘要: This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.
