Kit for treating gastrointestinal tract

1. A kit for use in treating a wall forming the upper portion of a gastrointestinal tract in a body of a human having an esophagus extending from a mouth through a lower esophageal sphincter to a stomach comprising a package, a needle assembly carried within the package and consisting of a single-walled flexible elongate tubular member having proximal and distal extremities and a tubular needle slidably disposed in the flexible elongate tubular member and movable from a retracted position in which the tubular needle is recessed within the distal extremity of the flexible elongate tubular member to an extended position in which the tubular needle projects distally of the flexible elongate tubular member, the flexible elongate tubular member having a length of at least approximately 34 centimeters so that when the distal extremity is in the vicinity of the lower esophageal sphincter the proximal extremity is outside of the body, and a fluid connector carried by the proximal extremity of the flexible elongate tubular member and coupled to the tubular needle, a syringe removably couplable to the fluid connector carried within the package and a container of a solution of a biocompatible polymer and a biocompatible solvent for forming a nonbiodegradable solid carried within the package whereby the solution is loaded from the container into the syringe and delivered from the syringe by means of the needle assembly into the wall to form a nonbiodegradable solid in the wall.

2. The kit of claim 1 wherein the flexible elongate tubular member is made from flexible plastic.

3. The kit of claim 1 further comprising an additional syringe and a container of the biocompatible solvent carried within the package.

4. The kit of claim 1 further comprising a delivery mechanism for supplying a plurality of discrete preselected amounts of the solution from the syringe to the needle assembly for introduction into the wall.

5. The kit of claim 1 wherein the solution includes a contrast agent for facilitating visualization of the nonbiodegradable solid in the wall.

6. A kit for use in treating a wall forming the upper portion of a gastrointestinal tract in a body of a human having an esophagus extending from a mouth through a lower esophageal sphincter to a stomach comprising a package, a needle assembly carried within the package and consisting of a single-walled flexible elongate tubular member having proximal and distal extremities and a tubular needle slidably disposed in the flexible elongate tubular member and movable from a retracted position in which the tubular needle is recessed within the distal extremity of the flexible elongate tubular member to an extended position in which the tubular needle projects distally of the elongate tubular member, the flexible elongate tubular member having a length of at least approximately 34 centimeters so that when the distal extremity is in the vicinity of the lower esophageal sphincter the proximal extremity is outside of the body, and a fluid connector carried by the proximal extremity of the flexible elongate tubular member and coupled to the tubular needle, and a container of a solution of a biocompatible polymer and a biocompatible solvent for forming a nonbiodegradable solid carried within the package whereby the solution in the container is delivered by means of the needle assembly into the wall to form a nonbiodegradable solid in the wall.

7. The kit of claim 6 wherein the flexible elongate tubular member is made from flexible plastic.

8. A kit for use in treating a wall having tissue and forming the upper portion of a gastrointestinal tract in a body of a human having an esophagus extending from a mouth through a lower esophageal sphincter to a stomach comprising a package, a needle assembly carried within the package and consisting of a single-walled flexible elongate tubular member having proximal and distal extremities and a tubular needle slidably disposed in the flexible elongate tubular member and movable from a retracted position in which the tubular needle is recessed within the distal extremity of the flexible elongate tubular member to an extended position in which the tubular needle projects distally of the flexible elongate tubular member, the flexible elongate tubular member having a length of at least approximately 34 centimeters so that when the distal extremity is in the vicinity of the lower esophageal sphincter the proximal extremity is outside of the body, and a connector carried by the proximal extremity of the flexible elongate tubular member and coupled to the tubular needle, a syringe removably couplable to the connector carried within the package and a container of a prepolymer composition for forming a nonbiodegradable solid carried within the package whereby the prepolymer composition is loaded from the container into the syringe and delivered from the syringe by means of the needle assembly into the tissue of the wall to form a nonbiodegradable solid in the tissue of the wall.

9. The kit of claim 8 wherein the flexible elongate tubular member is made from flexible plastic.

10. The kit of claim 8 wherein the container further includes a contrast agent for facilitating visualization in the wall of the body.

11. The kit of claim 8 further comprising a container of a biocompatible solvent carried within the package.
