An endovascular guide catheter includes a guide tube and a handle. The flexible guide tube has a distal end portion configured to deflect via actuation of a pull wire. The handle is coupled to the guide tube and comprises a steering assembly configured to actuate the pull wire to deflect the distal end portion of the guide tube. The steering assembly can comprise a stationary rack, a gear, a reel, and a slider. The gear engages the rack and the reel is coupled to and configured to rotate with the gear. The pull wire is coupled to the reel such that rotation of the reel causes the pull wire to wind or unwind around the reel. The slider is adapted for translation relative to the rack. Translation of the slider translates the reel relative to the rack and rotation of the gear along the rack rotates the reel.

Devices, systems, and methods for implanting expandable prostheses in the body lumens rely on stapling or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a stapling system is introduced within the expanded prosthesis to deploy a plurality of fasteners to at least one prosthesis end. The stapling system may apply a force to the prosthesis to modify the shape of the prosthesis to conform to the shape of the vessel wall. The stapling system can be deflected in one or more distinct steerable segments. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.
