Abstract

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.

Claims Analysis

Total Claims: 8

Claim 1

Independent Claim 65 words

Apparatus for placement at an angeological bifurcation of a vessel into two branched vessels comprising a first bifurcated graft member, at least partially supported by a bifurcated stent member, defining two lumens, at least one of which is configured to be disposed entirely within said vessel and is adapted to mate with a second stent configured to extend into one of the two branched vessels.

Claim 2

Dependent Claim 65 words

Claim 3

Dependent Claim 31 words

Apparatus as claimed in claim 1 further comprising a second stent, attached to said one lumen disposed entirely within said vessel, configured to extend into one of the two branched vessels.

Claim 4

Dependent Claim 28 words

Apparatus as claimed in claim 2, said second stent being tapered radially outwardly toward its proximal end and adapted to engage said lumen disposed entirely within said vessel.

Claim 5

Dependent Claim 21 words

Apparatus as claimed in claim 1, said lumen disposed entirely within the vessel being tapered radially inwardly toward its distal end.

Claim 6

Dependent Claim 47 words

Apparatus as claimed in claim 1, said bifurcated stent member further comprising a portion having a radiographic image that differs depending on rotational orientation of said bifurcated stent member, wherein the rotational orientation of said bifurcated stent member in the vessel is indicated by said radiographic image.

Claim 7

Dependent Claim 22 words

Apparatus as claimed in claim 5 wherein said portion having a radiographic image comprises a radiographic marker configured in a "V" shape.

Claim 8

Dependent Claim 43 words

Apparatus as claimed in claim 2, at least one of said bifurcated stent member and said second stent comprising a portion having a different radiopacity to facilitate proper alignment of said bifurcated stent member and said second stent with respect to one another.
