Abstract
The present embodiments describe an endograft having at least two branches extending from two fenestrations on the endograft body, and methods for deploying the same. In one example, the system comprises one internal branch that is relatively straight, and one external branch that is helically curved. The fenestrations may be circumferentially located on substantially the same side of the endograft main body, and distal regions of the branches may be circumferentially located on substantially opposite sides of the main body. The branches may be longitudinally non-overlapping. Connection stents may be configured to extend from the branches to provide fluid communication with peripheral vessels. Peripheral vessels may include the coronary or renal arteries. In another example, the branches are both external to the main endograft body.
