Abstract
The stent graft includes a main body and an external coupling. The main body extends along a longitudinal axis and includes proximal and distal ends. The external coupling extends away from the main body and defines an opening having a center. The main body includes a first bracketing stent extending about a proximal side of the external coupling. The first bracketing stent includes first and second peaks. The first peak is circumferentially aligned with the center of the external coupling. The first peak is proximal the second peak about the main body along the longitudinal axis.

A stent graft comprising:
- a main body extending along a longitudinal axis and including proximal and distal ends;
- and
- an external coupling extending away from the main body and defining an opening having a center;
- the main body includes a first bracketing stent extending along a proximal side of the external coupling, the first bracketing stent includes first and second peaks, the first peak circumferentially aligns with the center of the external coupling, and the first peak is proximal the second peak about the main body along the longitudinal axis, the first bracketing stent includes a first valley, the main body includes a second bracketing stent including second and third valleys, and the first and the second valleys longitudinally align on an opposite side of the main body from the external coupling.
