Apparatus and method of placement of a graft or graft system

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.

         2 . 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 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, the first opening being aligned with a first branch vessel when the first endoluminal prosthesis is deployed and the second opening being aligned with a second branch vessel when the second endoluminal prosthesis is deployed so that the main body graft does not cover access to the first branch vessel and the second branch vessel;   advancing a first tubular structure carrying a first stent through the first opening and into the first branch vessel;   advancing a second tubular structure carrying a second stent through the second opening and into the second branch vessel;   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.   
     
     
         3 . The method of  claim 2 , wherein the first lateral opening is diametrically opposite the second lateral opening. 
     
     
         4 . The method of  claim 2 , 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 2 , wherein deploying the first stent comprises expanding the first stent with a balloon. 
     
     
         8 . The method of  claim 2 , wherein the first branch vessel is the left renal artery and the second branch vessel is the right renal artery. 
     
     
         9 . The method of  claim 2 , wherein the second endoluminal prosthesis comprises a bifurcated graft. 
     
     
         10 . 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 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, the first opening being aligned with a first branch vessel when the first endoluminal prosthesis is deployed and the second opening being aligned with a second branch vessel when the second endoluminal prosthesis is deployed so that the main body graft does not cover access to the first branch vessel and the second branch vessel;   advancing a first tubular structure carrying a first stent through the first opening and into the first branch vessel;   advancing a second tubular structure carrying a second stent through the second opening and into the second branch vessel;   deploying a second endoluminal prosthesis in the main vessel, the second endoluminal prosthesis comprising a bifurcated graft;   deploying a first stent in the first branch vessel; and   deploying a second stent in the second branch vessel.   
     
     
         11 . The method of  claim 10 , wherein the first lateral opening is diametrically opposite the second lateral opening. 
     
     
         12 . The method of  claim 10 , further comprising delivering a first branch graft in the first branch vessel prior to deploying the first stent. 
     
     
         13 . The method of  claim 12 , further comprising delivering a second branch graft in the second branch vessel prior to deploying the second stent. 
     
     
         14 . The method of  claim 12 , wherein the first branch graft is connected to the main body of the first endoluminal prosthesis. 
     
     
         15 . The method of  claim 10 , wherein deploying the first stent comprises expanding the first stent with a balloon. 
     
     
         16 . The method of  claim 10 , wherein the first branch vessel is the left renal artery and the second branch vessel is the right renal artery. 
     
     
         17 . A method of delivering an endoluminal prosthesis system, the method comprising:
 deploying a first endoluminal prosthesis in an aorta, the first endoluminal prosthesis comprising a main body graft, 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, the first opening being aligned with a left renal artery when the first endoluminal prosthesis is deployed and the second opening being aligned with a right renal artery when the second endoluminal prosthesis is deployed so that the main body graft does not cover access to the left renal artery and the right renal artery;   advancing a first tubular structure carrying a first stent through the first opening and into the left renal artery;   advancing a second tubular structure carrying a second stent through the second opening and into the right renal artery;   deploying a second endoluminal prosthesis in an iliac artery;   deploying a first stent in the left renal artery; and   deploying a second stent in the right renal artery.
