Abstract

An intraluminal graft includes a tubular graft body extending along a cylindrical axis, a plurality of wires spaced apart from each other and arranged to circumferentially reinforce said tubular graft body along a substantial portion of its length, and a body surface including an inner surface region and an outer surface region. The body surface defines a plurality of apertures extending from an exterior space, and a first portion of a first wire is in the interior space while a second portion of the first wire is in the exterior space.

Claims

1. A prosthesis comprising:

(i) a bifurcated base structure which defines a common flow lumen and a pair of connector legs which define divergent flow lumens from the common flow lumen; and

(ii) a graft which is adapted to be anchored within one of the flow lumens of said bifurcated base structure to form a continuous extension of that lumen.

2. The prosthesis as defined in claim 1, wherein said bifurcated base structure is circumferentially reinforced at locations along its length by a plurality of separate spaced apart wires.

3. The prosthesis as defined in claim 2, wherein each of said separate spaced apart wires comprises two opposing ends, said ends being joined together on the outside surface of said bifurcated base structure.

4. The prosthesis as defined in claim 3, wherein said ends are joined together to form a tail.

5. The prosthesis as defined in claim 2, wherein at least one of said separate spaced apart wires is interwoven with said bifurcated base structure.

6. The prosthesis as defined in claim 2, wherein at least one of said separate spaced apart wires is attached to said bifurcated base structure via sutures.

7. The prosthesis as defined in claim 2, wherein at least one of said separate spaced apart wires is attached to said bifurcated base structure via adhesive.

8. The prosthesis as defined in claim 2, wherein at least one of the separate spaced apart wires has a different amplitude than a next adjacent wire.

9. The prosthesis as defined in claim 2, wherein one of the separate spaced apart wires is located at one end of said bifurcated base structure and has alternate crests or apices extending beyond said one end of said bifurcated base structure.

10. A prosthesis comprising:

a first graft comprising a proximal portion, a first distal portion, and a second distal portion;

said proximal portion defining a lumen and adapted to be disposed within a blood vessel in juxtaposition with a bifurcation;

said first distal portion defining a lumen and adapted to allow blood to flow from said proximal portion into a first branched blood vessel;

said second distal portion defining a lumen and adapted to allow blood to flow from said proximal portion into a second branched vessel; and

a second graft defining a lumen and adapted to be intravascularly inserted into a lumen of said first graft to allow blood to flow through the lumen defined by said second graft; and

wherein said first distal portion has a downstream end forming a skirt.
