Bifurcated endoluminal prosthesis
DCFirst Claim
1. An introducer for delivering, into the vasculature at an angeological bifurcation where a blood vessel branches into two branched vessels, a bifurcated endoluminal stent or prosthesis having a proximal portion adapted to be disposed in said blood vessel and a distal portion adapted to be disposed at least partially in one of said two branched vessels, said introducer comprising:
- (a) a tubular outer sheath;
(b) a proximal portion pusher slideably disposed at least partially within said outer sheath and adapted to engage a distal end of said proximal portion; and
(c) a distal portion pusher slideably disposed at least partially within said proximal portion pusher and adapted to engage a distal end of said distal portion.

Abstract
The invention comprises:
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.
