Abstract: Dual-wire lumen systems and methods of deployment for the same are discussed herein. Methods for deployment of dual-wire lumen systems include inserting a dilator system through a first branching portion of a branching stent prosthesis which includes the first and a second branching portions and a trunk portion. The dilator system includes a dilator and a first guidewire. The method further includes directing the dilator system towards an intersection between the first branching portion, the second branching portion, and the trunk portion of the branching stent prosthesis and advancing a distal end of the dilator toward the second branching portion. The method further includes advancing, at the intersection, a distal end of the first guidewire along the trunk portion through a port located on a sidewall of the dilator. The method further includes retracting the dilator through the first branching portion.
