System for delivering a prosthesis
DCFirst Claim
1. A system for delivering a prosthesis into the vasculature of a body in juxtaposition with an angeological bifurcation where a blood vessel branches into two branched vessels, said system comprising:
- (a) a bifurcated endoluminal prosthesis having a proximal portion configured to be disposed in the blood vessel and two distal portions, at least one of said distal portions being configured to remain in the blood vessel without extending across the angeological bifurcation;
(b) an outer sheath configured to contain said bifurcated endoluminal prosthesis; and
(c) a pusher slideably disposed at least partially within said outer sheath and configured to contact an end portion of said bifurcated endoluminal prosthesis in pushing relation therewith.

Abstract
An introducer for delivering into the vasculature a straight or bifurcated stent or prosthesis; a method for delivering into the vasculature a straight or bifurcated stent or prosthesis; a method of treating and angeological disease using a bifurcated stent; an endoluminal stent having perpendicular hoop members, each hoop member formed of wire in a sinuous configuration, at least some of juxtaposed apices in neighboring hoops being secured to one another, such stents also forming axially aligned segments in straight stents, and segments of bifurcated stents in particular embodiments. Certain embodiments of such stents also include barbs, fabric covering and radiopaque markers.

11. A system for introducing endoluminal prostheses into a vessel to define a continuous lumen, said system comprising:
-
a first introducer for introducing a first prosthesis into the vessel, said first prosthesis having a portion adapted for connection to another prosthesis; and
a second introducer for (a) introducing a second prosthesis in a radially compressed state into the vessel and into said portion of said first prosthesis, and (b) deploying said second prosthesis to connect to said portion of said first prosthesis and to define said continuous lumen through said first prosthesis and said second prosthesis. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

13. The system as recited in claim 11, said system being adapted for delivering said endoluminal prostheses into the vasculature of the body in juxtaposition with a bifurcation where a blood vessel branches into branched vessels, wherein said first introducer is configured to introduce said first prosthesis through one of said branched vessels, and wherein said second introducer is configured to introduce said second prosthesis through the other one of said branched vessels.
-
14. The system as recited in claim 13 wherein one of said endoluminal prostheses is a bifurcated prosthesis having a proximal portion adapted to be disposed in the blood vessel and a distal portion adapted to be disposed at least partially in one of the branched vessels.
-
15. The system as recited in claim 13 wherein one of said endoluminal prostheses is a bifurcated prosthesis having a proximal portion configured to be disposed in the blood vessel and two distal portions, at least one of said distal portions being configured to remain in the blood vessel without extending across the bifurcation.
-
16. The system as recited in claim 11 wherein at least one of said first prosthesis and said second prosthesis comprises a portion having a different radiopacity from said at least one of said first and second prosthesis, said portion having a radiographic image that is detectable using a detector outside the body.
-
17. The system as recited in claim 16 wherein said portion having said different radiopacity comprises at least one radiopaque marker.
-
18. The system as recited in claim 16 wherein said radiographic image of said portion differs depending on the rotational orientation of said at least one of said first and second prostheses so that said rotational orientation in the body lumen can be determined.
-
19. The system as recited in claim 18 wherein said portion having said different radiopacity is configured in a “
- V”
shape.
