A vascular repair device for treating aortic vascular damage, comprising: a) a main prosthesis having a graft component that includes an external surface and an internal surface, the graft component defining a main lumen, a proximal open end, a distal open end, and a first major longitudinal axis extending through the proximal open end and distal open end, and a midsection that narrows in a distal direction along the main lumen and defines four independent fenestrations (22, 24, 26, 28); b) a first internal prosthesis within the main lumen, the first internal prosthesis having a graft component, an external surface and an internal surface, and defining at least in part a first internal lumen, a proximal end located distally to the proximal open end of the main prosthesis, a distal end and a longitudinal axis extending through the first internal lumen, the proximal end and the distal end, and being substantially parallel to the first major longitudinal axis; c) a second internal prosthesis within the main lumen, the second internal prosthesis having a graft component, an external surface and an internal surface, and defining at least in part a second internal lumen, a proximal end located distally to the proximal open end of the main prosthesis, a distal end and a longitudinal axis extending through the second internal lumen, the proximal end and the distal end, and being substantially parallel to the first major longitudinal axis, and wherein the proximal end of the second internal prosthesis is distal to the proximal end of the first internal prosthesis; and d) four sub-prostheses (18, 19, 20, 21), each having a graft component defining a proximal end, 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 to a first and a second of the four independent fenestrations at the midsection of the main prosthesis and two other sub-prostheses extend distally from the distal end of the second internal prosthesis to a third and a fourth of the four independent fenestrations at the midsection of the main prosthesis, and wherein the sublumens provide fluid communication between the distal end of the first internal prosthesis and the second internal prosthesis and a respective fenestration of the four independent fenestrations. a) a main prosthesis having a graft component that includes an external surface and an internal surface, the graft component defining a main lumen, a proximal open end, a distal open end, and a first major longitudinal axis extending through the proximal open end and distal open end, and a midsection that narrows in a distal direction along the main lumen and defines four independent fenestrations (22, 24, 26, 28);
