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.
