Abstract: A self-expanding main vessel stent-graft (200) includes a trunk portion (204) configured for placement within the abdominal aorta and a bifurcated portion (220) configured for placement above the aortic bifurcation of the common iliac arteries. The trunk portion includes a proximal end section (210) having an anchor stent (222) and a seal stent (226) that accommodates a scallop or open-top fenestration (224); a suprarenal body section having at least one stent (228) of variable stiffness to accommodate branch vessel prosthesis deployed alongside the main vessel stent-graft; a branch connection section (214) having opposing couplings for connecting the main vessel stent-graft to branch vessel prostheses deployed within the renal arteries; an infrarenal body section (216) having at least one stent (230) of uniform stiffness; and a transition section (218) for transitioning into the bifurcated portion.

Abstract: A prosthetic assembly for repairing a target tissue defect within a target vessel region configured includes an exclusion structure sized to substantially bypass target tissue defect, and includes a branch assembly. The branch assembly can include a self-expanding outer branch prosthesis having an inflow region configured to deform to a non-circular cross- sectional-shape when deployed, and a support structure at least partially disposed within the inflow region. The support structure preserves blood flow to the branch vessel while the deformed inflow region inhibits blood leakage between and/or around the prosthetic assembly.
