1. A method of excluding a site of an aneurysm from blood flow comprising:
delivering a stent graft in a compressed configuration to an abdominal aorta of a patient, the stent graft including a main body, wherein the main body includes a main body stent, a main body graft material coupled to the stent, and an aperture disposed through a surface of the main body graft material, wherein the aperture includes a neck portion extending outwardly from the main body, wherein the neck portion includes a neck portion graft material extending from and integral with the main body graft material and a neck portion stent;
deploying the stent graft at the abdominal aorta by radially expanding the stent graft such that at least a portion of the main body is in apposition with a wall of the abdominal aorta and the neck portion is aligned with one of the renal arteries;
delivering an insert in a compressed configuration such that an insertion end of the insert is disposed within the neck portion; and
deploying the insert by radially expanding the insert such that the insertion end of the insert is disposed within the neck portion and a second portion of the insert extends from the neck portion and within one of the renal arteries,
wherein at least one of the neck portion and the insert includes a polymeric compound different from the neck portion graft material and the insert graft material, wherein the polymeric compound is located on an inside surface of the neck portion graft material, an outside surface of an insertion end of the insert graft material, or on both the inside surface of the neck portion graft material and the outside surface of the insertion end of the insert graft material.
