Systems and methods with graft body, inflatable fill channel, and filling structure

Abstract

A system for placement in at least one blood vessel includes a main graft body, one or more inflatable channels, and a filling structure. The one or more inflatable channels are attached to the main graft body. The filling structure is inflatable around at least a portion of the main graft body and at least a portion of at least one of the one or more inflatable channels. Various systems further include a graft extension that is insertable into a lumen formed by the main graft body, where the filling structure is inflatable around at least a portion of the graft extension. A method includes inserting a main graft body into a blood vessel, filling an inflatable channel attached to the main graft body, and filling a filling structure to inflate around at least a portion of the main graft body and at least a portion of the inflatable channel.

What is claimed is: 
     
         1 . A system for placement in at least one blood vessel, the system comprising:
 a main graft body;   one or more inflatable channels attached to the main graft body; and   a filling structure inflatable around at least a portion of the main graft body and at least a portion of at least one of the one or more inflatable channels.   
     
     
         2 . The system of  claim 1 , further comprising:
 a graft extension at least partially insertable into a lumen formed by the main graft body.   
     
     
         3 . The system of  claim 2 ,
 wherein the filling structure is inflatable around at least a portion of the graft extension.   
     
     
         4 . The system of  claim 2 ,
 wherein the filling structure is attached to the graft extension.   
     
     
         5 . The system of  claim 2 ,
 wherein the filling structure is attached to the graft extension at two or more discrete locations along a length of the graft extension.   
     
     
         6 . The system of  claim 2 ,
 wherein the filling structure is attached to the graft extension only at one or more locations that are away from a proximal end of the graft extension; and   wherein the filling structure is expandable around at least a portion of the proximal end of the graft extension.   
     
     
         7 . The system of  claim 2 , further comprising:
 a second graft extension at least partially insertable into the main graft body.   
     
     
         8 . The system of  claim 7 ,
 wherein the filling structure is attached to the second graft extension.   
     
     
         9 . The system of  claim 7 ,
 wherein the filling structure is insertable into the blood vessel separate from the main graft body, the graft extension, and the second graft extension.   
     
     
         10 . The system of  claim 2 ,
 wherein the filling structure is expandable to fill a space between a wall of the at least one blood vessel and each of the at least a portion of the main graft body, the at least a portion of the at least one of the one or more inflatable channels, and at least a portion of the graft extension.   
     
     
         11 . The system of  claim 1 ,
 wherein the filling structure is attached to the main graft body.   
     
     
         12 . The system of  claim 11 ,
 wherein the filling structure is expandable beyond a distal end of the main graft body.   
     
     
         13 . The system of  claim 11 ,
 wherein a particular inflatable channel of the one or more inflatable channels is located between a proximal end of the main graft body and a location of attachment of the filling structure to the main graft body.   
     
     
         14 . The system of  claim 13 ,
 wherein a second particular inflatable channel of the one or more inflatable channels is located between a distal end of the main graft body and the location of attachment of the filling structure to the main graft body.   
     
     
         15 . The system of  claim 1 , further comprising:
 a second filling structure inflatable around at least a portion of the filling structure.   
     
     
         16 . A method, comprising:
 inserting a main graft body into at least one blood vessel;   filling one or more inflatable channels attached to the main graft body; and   filling a filling structure to inflate around at least a portion of the main graft body and at least a portion of at least one of the one or more inflatable channels.   
     
     
         17 . The method of  claim 16 ,
 wherein the filling structure is attached to the main graft body   
     
     
         18 . The method of  claim 16 , further comprising:
 inserting at least a portion of a graft extension into a lumen formed by the main graft body;   wherein the filling structure extends around at least a portion of the graft extension.   
     
     
         19 . The method of  claim 16 ,
 wherein the filling structure is attached to a graft extension; and   wherein the method further comprises inserting at least a portion of the graft extension into a lumen formed by the main graft body.   
     
     
         20 . The method of  claim 16 , further comprising:
 filling a second filling structure to inflate around at least a portion of the filling structure.
