Abstract

An intraluminal device that is adapted to be positioned at the gastro-esophageal (GE) region of a recipient includes a wall defining an esophageal portion that is configured to the size and shape of a portion of the esophagus and a cardiac portion that is configured to the size and shape of the cardiac portion of the stomach. A connector is connected with the esophageal and cardiac portions and configured to be positioned at the GE junction. A separable portion of the connector is separable from the esophageal portion and/or the cardiac portion. The separable portion of the connector is separably connected with the wall with a removable attachment that is adapted to be separated in situ.

         7 . The device as claimed in  claim 1 , wherein said wall comprises a structural mesh defining intersections and covered with a biocompatible coating wherein a separable portion of said connector extending over at least one of said intersections and under at least one other of said intersections and wherein said removable attachment is between said separable portion and said mesh keeping said connector from sliding with respect to said intersections. 
     
     
         8 . The device as claimed in  claim 7 , wherein said removable attachment comprises a filament between said distal portion and said mesh. 
     
     
         9 . The device as claimed in  claim 8  including a bead on said filament to provide access to said filament. 
     
     
         10 . The device as claimed in  claim 7 , wherein said connector extends over a plurality of intersections and under at least one intersection between said plurality of intersections. 
     
     
         11 . The device as claimed in  claim 1 , wherein said connector comprises a filament and a biocompatible coating over said filament. 
     
     
         12 . The device as claimed in  claim 1 , wherein said connectors include a therapeutic agent eluting coating. 
     
     
         13 . The device as claimed in  claim 1  including a therapeutic agent dispensing reservoir at a distal portion of said esophageal portion that is adapted to dispense a therapeutic agent to said connector. 
     
     
         14 . The device as claimed in  claim 1 , wherein said device comprises a bariatric device used to treat excess body mass or a metabolic device used to treat metabolic disease. 
     
     
         15 . An intraluminal device adapted to be positioned at the gastro-esophageal (GE) region of a recipient, comprising:
 a wall defining an esophageal portion that is configured to the size and shape of a portion of the esophagus and a cardiac portion that is configured to the size and shape of the cardiac portion of the stomach; and   a connector connected with said esophageal and cardiac portions said connector configured to be positioned at the GE junction, wherein a separable portion of said connector being separable from at least one chosen from said esophageal portion and said cardiac portion, said separable portion of said connector being separably connected with said wall; and   wherein said esophageal portion and said cardiac portion are adapted to be separately explanted from the recipient.   
     
     
         16 . An intraluminal device adapted to be deployed at the gastroesophageal (GE) region of a recipient, comprising:
