1. A stent-graft system comprising:
a bifurcating branch device comprising:
a body segment comprising a nonflared proximal portion and a flared distal portion, the nonflared proximal portion extends between a proximal end and a distal end, the flared distal portion extends from the distal end of the nonflared proximal portion to a distal end; and
a lower segment attached to the flared portion, the lower segment comprising:
a proximal lower segment extending from the distal end of the flared distal portion of the body segment to a distal end;
a first branch limb extending from the distal end of the proximal lower segment; and
a second branch limb extending from the distal end of the proximal lower segment,
the nonflared proximal portion and the flared distal portion of the body segment collectively comprise a single integrated non-overlapping graft material.
