Abstract

An endoluminal prosthesis system deployable in a region of a patient'"'"'s vasculature having one or more branch vessels, having a main graft body having a first opening in a wall portion of the main graft body and a pre-loaded guidewire positioned inside the main graft body and advanced through the first opening. One or more branch grafts can be attached to the main graft body to cover one or more openings in the main graft body.

Claims

1. A method of delivering an endoluminal prosthesis system, the method comprising:

deploying a first endoluminal prosthesis in a main vessel, the first endoluminal prosthesis comprising a main body graft, a first end, a second end, a single lumen extending from the first end to the second end, a first lateral opening in a wall portion of the main body graft, and a second lateral opening in the wall portion of the main body graft;

positioning a first hollow tubular member that passes over a first guidewire and supports a balloon on a distal end of the first hollow tubular member through the first lateral opening into a first branch vessel prior to deploying a distal end of the first endoluminal prosthesis;

positioning a second hollow tubular member that passes over a second guidewire and supports a balloon on a distal end of the first hollow tubular member through the second lateral opening into a second branch vessel prior to deploying a distal end of the first endoluminal prosthesis;

inflating the balloon on the distal end of the first hollow tubular member; and

inflating the balloon on the distal end of the second hollow tubular member.

2. The method of claim 1, wherein the first lateral opening is diametrically opposite the second lateral opening.

3. The method of claim 1, further comprising

deploying a second endoluminal prosthesis in the main vessel, the second endoluminal prosthesis comprising a main body graft, a portion of the main body graft of the second endoluminal prosthesis being deployed inside of the first endoluminal prosthesis, another portion of the main body graft of the second endoluminal prosthesis extending out of the first endoluminal prosthesis;

deploying a first stent in the first branch vessel; and

deploying a second stent in the second branch vessel.

4. The method of claim 3, further comprising

delivering a first branch graft in the first branch vessel prior to deploying the first stent.

5. The method of claim 4, further comprising delivering a second branch graft in the second branch vessel prior to deploying the second stent.

6. The method of claim 4, wherein the first branch graft is connected to the main body of the first endoluminal prosthesis.

7. The method of claim 3, wherein deploying the first stent comprises expanding the first stent with a balloon that extends into the first branch vessel.

8. The method of claim 3, wherein the second endoluminal prosthesis comprises a bifurcated graft.

9. The method of claim 1, wherein the first branch vessel is the left renal artery and the second branch vessel is the right renal artery.
