Abstract

This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.

         5 . The endovascular graft of  claim 2  wherein the polyethylene glycol diacrylate is present in a proportion ranging from about 50 to about 55 weight percent.  
     
     
         6 . The endovascular graft of  claim 2  wherein the polyethylene glycol diacrylate has a molecular weight ranging from about 350 to about 850.  
     
     
         7 . The endovascular graft of  claim 2  wherein the pentaerthyritol tetra 3(mercaptopropionate) is present in a proportion ranging from about 22 to about 27 weight percent.  
     
     
         8 . The endovascular graft of  claim 2  wherein the glycylglycine is present in a proportion ranging from about 22 to about 27 weight percent.  
     
     
         9 . The endovascular graft of  claim 1  wherein the inflation material is radiopaque.  
     
     
         10 . The endovascular graft of  claim 9  wherein the inflation material comprises a radiopaque material that is soluble in glycylglycine.  
     
     
         11 . The endovascular graft of  claim 9  wherein the inflation material becomes less radiopaque over time.  
     
     
         12 . The endovascular graft of  claim 11  wherein the inflation material comprises a radiopaque material comprising a blend of a soluble contrast agent and an insoluble contrast agent.  
     
     
         13 . The endovascular graft of  claim 1  wherein the soluble contrast agent comprises an iodinated aqueous solution and the insoluble contrast agent comprises barium sulfate.  
     
     
         14 . The endovascular graft of  claim 1  wherein a post-cure elastic modulus of the inflation medium is between about 175 and about 250 pounds per square inch.  
     
     
         15 . The endovascular graft of  claim 14  wherein the inflation medium exhibits a cure time between about two minutes and about ten minutes.  
     
     
         16 . The endovascular graft of  claim 1  wherein the inflation medium additionally comprises saline or other inert biocompatible material.  
     
     
         17 . The endovascular graft of  claim 16  wherein the inflation medium comprises between about 20 and about 50 percent by volume saline.  
     
     
         18 . The endovascular graft of  claim 1  wherein the inflation medium comprises polyethylene glycol diacrylate, a thiolated polyethyleneamine, and a buffer.  
     
     
         19 . The endovascular graft of  claim 1  wherein the inflation medium comprises polyethylene glycol diacrylate, a thiolated tetronic, and a buffer.  
     
     
         20 . The endovascular graft of  claim 1  wherein the graft body section comprises an inflatable channel in fluid communication with the inflatable cuff.  
     
     
         21 . The endovascular graft of  claim 20  wherein the inflatable cuff is disposed at a proximal portion of the graft body section and further comprising a second inflatable cuff disposed at a distal portion of the graft body section and wherein the second inflatable cuff is in fluid communication with the inflatable channel and inflatable cuff.  
     
     
         22 . An endovascular graft comprising: 
 a main body portion having at least one inflatable cuff,    a first bifurcated portion forming a continuous lumen with the main body portion, said lumen configured to confine a flow of fluid therethrough,    at least one inflatable channel extending from the first bifurcated portion to the main body portion,    wherein the inflatable cuff is in fluid communication with the inflatable channel, and    wherein the inflatable channel and inflatable cuff contain a three-component inflation medium.    
     
     
         23 . The endovascular graft of  claim 22  wherein the inflation medium comprises the combination polyethylene glycol diacrylate, pentaerthyritol tetra 3(mercaptopropionate), and a buffer.  
     
     
         24 . The endovascular graft of  claim 22  wherein the inflation material is radiopaque.

         29 . The kit of  claim 27  wherein each of the three components of the inflation medium is packaged separately.  
     
     
         30 . The kit of  claim 27  wherein the graft body section further comprises an inflatable channel in fluid communication with the inflatable cuff.  
     
     
         31 . The kit of  claim 28  further comprising a second inflatable cuff disposed at a distal portion of the graft body section in fluid communication with the inflatable channel and inflatable cuff.  
     
     
         32 . The kit of  claim 27  wherein the graft body section comprises a main body portion and at least one bifurcated portion forming a continuous lumen with the main body portion, said lumen configured to confine a flow of fluid therethrough.
