Abstract
The present embodiments provide an endoluminal prosthesis deployment system and method for deploying the prosthesis for cannulation of branch vessels. The prosthesis includes an anterior fenestration and a posterior opening. A guide is disposed to exit the prosthesis lumen through a lateral fenestration, enter through the anterior fenestration, and exit the prosthesis lumen through the posterior opening. A sheath can be preloaded over the branch wire at the lateral fenestration for vessel cannulation, such as in renal arteries. The sheath can include another branch wire that extends from the lateral fenestration to another lateral fenestration. An end of the guide is retracted after partial expansion of the prosthesis, and another sheath is inserted over the retracted guide and moved through the posterior opening and to the anterior fenestration. A separate branch guide wire is then directed through the sheath for vessel cannulation, such as the SMA.
