Claim 0:
1. A vascular repair device (10) for treating aortic vascular damage, comprising:
a) a main prosthesis (12) having a graft component (30) that includes an external surface (32) and an internal surface (34), the graft component defining a main lumen (36), a proximal open end (38), a distal open end (40), a first major longitudinal axis (42) extending through the proximal open end (38) and distal open end (40), a midsection (44) that narrows in a distal direction along the main lumen (36), and wherein the main prosthesis defines four independent fenestrations (22, 24, 26, 28);
b) a first internal prosthesis (14) within the main lumen (36), the first internal prosthesis having a graft component (50), an external surface (52) and an internal surface (54), and defining at least in part a first internal lumen (56), a proximal end (58) located distally to the proximal open end (38) of the main prosthesis (12), a distal end (60) and a longitudinal axis (62) extending through the first internal lumen (56), the proximal end (58) and the distal end (60), and being substantially parallel to the first major longitudinal axis (42);
c) a second internal prosthesis (16) within the main lumen (36), the second internal prosthesis having a graft component (64), an external surface (66) and an internal surface (68), and defining at least in part a second internal lumen (70), a proximal end (72) of the second internal prosthesis (16) located distally to the proximal open end (38) of the main prosthesis (12), a distal end (76) of the second internal prosthesis (16), and a longitudinal axis (79) extending through the second internal lumen (70), the proximal end (72) of the second internal prosthesis (16) and the distal end (76) of the second internal prosthesis (16), and being substantially parallel to the first major longitudinal axis (42), and wherein the proximal end (72) of the second internal prosthesis (16) is distal to the proximal end (58) of the first internal prosthesis (14); and
d) four sub-prostheses (18, 19, 20, 21), each having a graft component defining a proximal end and a distal end, at least a portion of a sublumen and a major longitudinal axis (78, 80, 82, 84) extending through the proximal and distal ends and through the sublumen, the graft component of the sub-prostheses each having an external surface and an internal surface, wherein two sub-prostheses extend distally from the distal end of the first internal prosthesis (14) to a first and a second of the four independent fenestrations at the midsection (44) of the main prosthesis (12) and two other sub-prostheses extend distally from the distal end of the second internal prosthesis (16) to a third and a fourth of the four independent fenestrations of the main prosthesis (12), and wherein the sublumens provide fluid communication between the distal end of the first internal prosthesis (14) and the second internal prosthesis (16) and a respective fenestration of the four independent fenestrations, wherein a portion of the internal surface of the graft component of the main prosthesis proximate to the proximal open end defines a portion of the internal lumen (176) of at least one of the first internal prosthesis and the second internal prosthesis, and each sub-prosthesis is affixed to the main prosthesis (12).
