1. An aortic graft assembly, comprising:
- a) a tubular aortic component that defines a tunnel lumen and includes a proximal end and a distal end connected by a wall of the tubular aortic component, the wall defining a wall aperture that is between the proximal and distal ends, the wall aperture having a proximal end and a distal end, the proximal end of the wall aperture including an arch that lies in a first plane extending perpendicular to a major longitudinal axis of the tubular aortic component when viewed orthogonally to the major longitudinal axis;
b) a tunnel graft connected to the wall of the tubular aortic component and extending from the wall aperture and within the tunnel lumen of the tubular aortic component toward the proximal end of the tubular aortic component, the tunnel graft having a proximal end and a distal end, and defining a tunnel graft lumen that extends between the distal end and the proximal end of the tunnel graft lumen, the distal end being at the wall aperture of the tubular aortic component, and wherein the length of the proximal end of the wall aperture in the first plane is greater than the diameter of the tunnel graft lumen in a second plane extending orthogonally to the major longitudinal axis at a point proximal to the proximal end of the wall aperture;
c) a proximal stent that supports the proximal end of the tubular aortic component; and
d) a distal stent that supports the distal end of the tubular aortic component.

Abstract
An aortic graft assembly includes a tubular component that defines a wall aperture having a proximal end that extends perpendicular to a major longitudinal axis of the tubular aortic component, and a tunnel graft connected to the wall of the tubular aortic component and extending from the wall aperture toward a proximal end of the tubular aortic component. The method for delivery of the aortic graft assembly includes delivering the aortic graft assembly through the wall aperture and into interferring relation with the tunnel graft.
