1. A prosthesis, comprising:
a tubular graft body defining a main lumen extending between an inflow end and an outflow end of the graft body;
a stent structure coupled along the graft body;
a trough defined by a boundary formed at a sidewall of the graft body and extending away from the side wall, the boundary comprising a first axial side, a second side axially spaced from the first axial side, a first circumferential side, and a second circumferential side circumferentially spaced from the first circumferential side and disposed between the first axial side and the second axial side;
an internal branch defining a branch lumen and extending away from the trough toward one of the inflow or outflow ends of the graft body within the main lumen, wherein the trough, the branch lumen, and the main lumen are in fluid communication, and
a trough frame disposed only partially about the boundary;
wherein the first axial side is substantially perpendicular with the longitudinal axis,
wherein the first and second circumferential sides taper inwardly along the same direction of the side branch,
wherein a portion of the boundary at the first axial side provides an unobstructed transition surface between the trough and the sidewall that is frameless.
