Prosthesis Fixation Apparatus and Methods
First Claim
1. A tubular prosthesis comprising:
- a tubular graft having a first end margin, a second end margin and a central portion therebetween; and
an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of said apexes, and a second end defined at least in part by a second group of said apexes, said undulating stent being secured to said tubular graft in a manner such that it can be inverted to extend generally in the same direction as said tubular graft with one end thereof forming an end of said tubular prosthesis and pointing away from said central portion of said tubular graft.

Abstract
A tubular prosthesis comprises a tubular graft; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of the apexes, and a second end defined at least in part by a second group of the apexes, the first group of apexes being pivotally attached to the tubular graft so as to form a plurality of circumferentially arranged hinges about which the stent can pivot so that the second group of apexes can move between a position where they are inside the tubular graft and a position where they are outside the tubular graft. In one embodiment a tubular prosthesis comprises a tubular graft having a first end margin, a second end margin and a central portion therebetween; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of the apexes, and a second end defined at least in part by a second group of the apexes, the undulating stent being secured to the tubular graft in a manner such that it can be inverted to extend generally in the same direction as the tubular graft with one end thereof forming an end of said tubular prosthesis and pointing away from the central portion of the tubular graft.

19. A tubular prosthesis delivery system comprising:
-
a sheath having a distal deployment end and a proximal end; a radially compressed stent-graft, which has a first end and a second end and is slidably disposed in said sheath and further includes an undulating stent having a plurality of apexes, a first end of the stent being defined at least in part by a first group of said apexes, and a second end of the stent being defined by at least in part by a second group of said apexes, said undulating stent being inverted with said second group of apexes directed toward said distal deployment end of said sheath. - View Dependent Claims (20, 21, 22)

- 23. A method of delivering a tubular prosthesis in a vessel in a human patient comprising delivering a tubular prosthesis having an inner surface, an outer surface, and an inverted stent forming the leading end of the prosthesis as it is delivered to a target site in a human vessel and deploying the prosthesis such that the inverted stent folds back over one of the inner and outer surface of the tubular prosthesis.

25. A method of coupling a first tubular prosthesis in a branch vessel to a second tubular prosthesis in a vessel from the branch vessel branches comprising:
-
delivering a first tubular prosthesis, which is restrained in a sheath and has a leading end and a trailing end, which includes an inverted stent, through a fenestration in a second tubular prosthesis, which is positioned in a first vessel, and into a second vessel that branches from the first vessel; positioning the inverted stent inside the first tubular prosthesis; and retracting the sheath to release the first tubular prosthesis and allow the trailing end to move radially outward against an inner surface of the second prosthesis adjacent the branch vessel to form a seal between the first and second prostheses. - View Dependent Claims (26)

27. A tubular prosthesis comprising:
-
a tubular graft; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of said apexes, and a second end defined at least in part by a second group of said apexes, said first group of apexes being pivotally attached to said tubular graft so as to form a plurality of circumferentially arranged hinges about which the stent can pivot so that said second group of apexes can move between a position where they are inside the tubular graft and a position where they are outside the tubular graft.
