An endoluminal repair of abdominal aortic aneurysms at the aortic and iliac bifurcation. In particular, a deployment system and graft are disclosed for deploying the bifurcated graft within both iliac branches, as well as the aortic trunk, from a single vascular access. The disclosed deployment system includes a delivery catheter having a releasable restraint for the main body section of the graft and separate releasable restraints for each of the first and second branch sections of the graft.

[ What is claimed is:] [1.]1. A single puncture bifurcation graft deployment system, comprising:an elongate, flexible catheter body, having a proximal end and a distal end, said catheter body having a user manipulating portion at said proximal end;a main vessel graft restraint, for restraining a main vessel portion of a bifurcated graft;a first branch vessel graft restraint, for restraining a first branch vessel portion of the graft, wherein the first branch vessel graft restraint is separate from and oriented proximal to the main vessel graft restraint with respect to the catheter; anda second branch vessel graft actuator, separate from the main vessel graft restraint and the first branch vessel graft restraint, for actuating a second branch vessel portion of the graft;wherein each of the main vessel graft restraint, first branch vessel graft restraint, and the second branch vessel graft actuator are operable such that the bifurcated graft is implantable by way of a single vascular access site.
