Devices, systems, and methods for prosthesis delivery and implantation, including a prosthesis assembly
First Claim
1. A prosthesis assembly for a blood vessel or hollow body organ comprising a main body component having a cephalad portion and a caudal portion and including a prosthetic material, the prosthetic material having an interior and comprising a main body lumen, a main body lumen caudal stent, a lumen extension including a prosthetic material having an interior and at least one lumen extension stent, the lumen extension being sized and configured to be telescopically fitted within the main body lumen and to increase the length of the main body lumen, and at least one of the main body lumen caudal stent and the lumen extension stent including at least a portion having a bend extending away from the stent, the at least one bent portion engaging the other of the at least one of the main body lumen caudal stent and the lumen extension stent to prevent longitudinal migration of the lumen extension with respect to the main body component.

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.

6. A prosthesis assembly for a blood vessel or hollow body organ comprising
a main body component having a cephalad portion and a caudal portion and including a prosthetic material, the prosthetic material having an interior and including a seam joining opposing surfaces of the prosthetic material together to form an internal septum extending at least a portion of the interior to form a multi-lumen flow channel, the multi-lumen flow channel comprising at least a first main body lumen and a second main body lumen with the first main body lumen extending beyond the second main body lumen, the first main body lumen and the second main body lumen sharing a portion of the internal septum, a first main body lumen caudal stent and a second main body lumen caudal stent being staggered in position with respect to each other such that the stent in the first main body lumen do not overlap or align with the stent in the second main body lumen, a first lumen extension including a prosthetic material and at least one first lumen extension stent, the first lumen extension being sized and configured to be telescopically fitted within the first main body lumen and to increase the length of the first main body lumen, a second lumen extension including a prosthetic material and at least one second lumen extension stent, the second lumen extension being sized and configured to be telescopically fitted within the second main body lumen and to increase the length of the second main body lumen, and means for coupling the first lumen extension to the first main body lumen and the second lumen extension to the second main body lumen, the means for coupling preventing longitudinal migration of the first and second lumen extensions with respect to the man body component.
