Abstract

A vascular repair device assembly includes a main prostheses, first internal prostheses, an optional second internal prostheses, and at least two sub-prostheses. Methods for delivering vascular repair devices include delivering a vascular repair device through a blood vessel to the aneurysm site, aligning a proximal open end of a main prosthesis cranially to the site of the aneurysm patient and directing a distal end of at least one additional one vascular repair device through a proximal end of at least a first internal lumen, and aligning the proximal end of the additional vascular repair device into a distal end of the at least one sub-prosthesis.

Claims

1. 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 including a proximal section, a midsection, a distal section, and a planar section between the proximal section and the midsection, the planar section defining openings, and wherein the proximal section defines a proximal open end, the midsection extends distally from a first of the openings of the planar section, and the distal section defines a distal open end, the proximal section defining a proximal lumen and a first major longitudinal axis extending through the center of the proximal lumen;

b) a first internal prosthesis within the proximal 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 distal 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 proximal 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 distal to the proximal end of the first internal prosthesis, a distal end and a longitudinal axis extending through the second internal lumen, the proximal end of the second internal prosthesis and the distal end of the second internal prosthesis, and being substantially parallel to the first major longitudinal axis, and wherein the first and second internal prostheses are on one side of a plane bisecting the proximal lumen; and

d) two pairs of sub-prostheses, each of the sub-prostheses of the two pairs of sub-prostheses having a graft component defining a proximal end, a distal end, at least a portion of a sublumen and a longitudinal axis extending through the proximal end and the distal end of each of the respective sub-prostheses and through the sublumens of each of the respective sub-prostheses, the graft component of each of the sub-prostheses having an external surface and an internal surface, wherein a first pair of the sub-prostheses extends distally to a second and a third of the openings defined by the planar section, and the second pair of the sub-prostheses extends distally to a fourth and a fifth of the openings defined by the planar section.

2. The vascular repair device of claim 1, wherein the midsection narrows in a distal direction along the main prosthesis.
