<p>The present invention provides modular intraluminal tubular prostheses (60), particularly stents and stent grafts (10), for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or 'prosthetic modules' (66) may be selectively combined to form a composite prosthesis having characteristics which are tailored to the specific requirements of the patient. Each prosthetic module (66) preferably includes one or more standard interface ends (84) for engaging another module (66), the module/module interface (74, 76) typically comprising ends which overlap and/or lock within a predetermined axial range. Advantageously, the axial length, cross section, perimeter, resilient expansive force, axial flexibility, liner permeability, liner extensibility, radial conformability, liner/tubal wall sealing and anchoring, and other prosthetic characteristics may be varied along the axis of the composite prosthesis, and also along the axis of each prosthetic module. The modules (66) are preferably individually introduced into a lumen system (100) of a patient body so that the composite prosthesis (64) is assembled in situ.</p> |
