Abstract:
An intralumenally implantable prosthesis including:a structural layer including a single elongate primary section extended in a longitudinal direction, the structural layer further including a plurality of secondary sections extended substantially transversally from the primary section and curved about an axis substantially parallel to the primary section, whereby the structural layer is thermally set so to conform, when in a substantially relaxed and fully deployed state, to a cylindrical shape having a predetermined radius,wherein the secondary sections are flexible to allow a radial reduction of the structural layer to a reduced-radius delivery profile responsive to an external force, and wherein the structural layer requires a continued application of the external force to maintain the reduced-radius delivery profile and alternatively tends to return to the substantially relaxed and fully deployed state upon removal of the external force; anda substantially continuous and compliant graft layer, supported by the structural layer, tending to conform to the shape of the structural layer, and substantially impervious to blood.
