Abstract
A bifurcated graft having a trunk portion and two limb portions, each defined by a docking end and a non-docking end, that is assembled in-situ. The trunk and limb portions are supported by a combination of full and partial stent structures that are connected by longitudinal stent struts to form a continuous stent lattice. The diameters of the docking sections may be standardized such that any limb portion may be inserted into any trunk portion, providing the same degree of mechanical interference for trunk and limb portions having non-docking ends of various diameters.
