23. A modular exclusion device useful for implantation in an aneurysmal site in a blood vessel comprising:
-
a main body including a plurality of main body stents aligned co-axially and main body graft material coupled to the stents such that the main body is substantially tubular; 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 such that a neck longitudinal axis is substantially perpendicular to a main body longitudinal axis, wherein the neck portion includes neck portion graft material extending from and integral with the main body graft material. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A modular exclusion device useful for implantation in an aneurysmal site in a blood vessel comprising:
-
a main body including a plurality of main body stents aligned co-axially and main body graft material coupled to the stents such that the main body is substantially tubular and includes an open main body lumen disposed therethrough; 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 and an open neck lumen disposed through the neck portion; and an insert including an insert graft material in a substantially tubular shape, wherein the insert includes an insertion end disposed within the neck lumen and not extending into the main body lumen. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44)
