Abstract
Devices, systems, and methods for implanting radially expandable prostheses in the body lumens rely on tacking 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 fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. 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.
