Abstract:
1. An intraluminal prosthesis for strengthening a main lumen and a branch lumen in direct fluid communication with the main lumen, the prosthesis comprising: a first graft comprising a first tubular flexible body including a wall with an interior and a fenestration through the wall; a second graft having a second tubular flexible body and a proximal end and a distal end, wherein the fenestration of the first graft is dimensioned to receive the second tubular flexible body; and a self-expanding zigzag stent configured to anchor said second graft to the first graft, the self-expanding zigzag stent including a plurality of connecting segments and bends interconnecting the connecting segments, the bends comprising a set of proximal bends and a set of distal bends, the distal bends of the self-expanding zigzag stent attached to the proximal end of the second graft, wherein each of the connecting segments of the self-expanding zigzag stent includes a concave curvature configured to extend each connecting segment proximally away and radially outward from the proximal end of the second graft, wherein the self-expanding zigzag stent extends through the fenestration, and the proximal bends are disposed substantially radially outward from the fenestration and contact the first graft interior wall.
