An intraluminal prosthesis (20) for strengthening a main lumen and a branch lumen in direct fluid communication with the main lumen includes a tubular graft (20) and a flexible stent (210). The tubular graft includes a flexible body having a wall with a fenestration (17). The flexible stent (210) includes a body with at least one open space to encourage tissue prolapse. The flexible stent (210) may be configured for intraluminal coupling to the fenestration (17) of the tubular graft, so that the entire prosthesis may be assembled and anchored into a main lumen and a branch lumen with a minimally invasive procedure. The open space or spaces can encourage tissue prolapse, which may act to anchor the flexible stent (221 ) to the branch lumen. |
