Method for treating morbid obesity
View Patent ↗A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a stomach and a pyloric sphincter and a wall forming the stomach and pyloric sphincter. At least one implant is formed in the wall in the vicinity of the pyloric sphincter to inhibit emptying of the stomach.
1. A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a stomach and a pyloric sphincter formed by a wall having a muscle layer comprising the step of forming at least one implant in the muscle layer of the wall to inhibit emptying of the stomach.
2. The method claim 1 wherein the forming step includes the step of forming a plurality of implants in the wall in the vicinity of the pyloric sphincter.
3. The method of claim 2 wherein the forming step includes the step of forming a plurality of circumferentially-disposed implants in the wall in the vicinity of the pyloric sphincter.
4. The method of claim 1 wherein the implant is arcuate shaped.
5. The method of claim 1 further comprising the step of inhibiting the ability of the stomach to expand so as to prolong satiety.
6. The method of claim 5 wherein the inhibiting step includes the step of forming a wall across a portion of the stomach to exclude a portion of the stomach from use.
7. The method of claim 1 wherein the forming step includes injecting a biocompatible solution having a biocompatible polymer and a biocompatible solvent into the wall.
8. The method of claim 7 wherein the biocompatible solution includes a contrast agent.
9. The method of claim 7 wherein the biocompatible solution of the biocompatible polymer and the biocompatible solvent has a composition comprising from about 2.5 to about 8.0 weight percent of a biocompatible polymer, from about 10 to about 40 weight percent of a water insoluble biocompatible contrast agent and from about 52 to about 87.5 weight percent of a biocompatible solvent.
10. A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending though a stomach formed by a wall comprising the step of introducing a biocompatible solution into the wall to form at least one implant in the wall of the stomach to provoke longer periods of satiety.
11. The method of claim 10 wherein the forming step includes the step of forming a plurality of implants in the wall of the stomach.
12. The method of claim 11 wherein the plurality of implants extend across a portion of the stomach.
13. The method of claim 11 wherein the plurality of implants extend around the stomach.
14. The method of claim 10 wherein the wall has a muscle layer, the at least one implant being formed in the muscle layer of the wall.
15. The method of claim 10 wherein the forming step includes the step of forming at least one implant in the wall of the stomach to decrease the contractility of the wall.
16. The method of claim 10 wherein the forming step includes the step of forming at least one implant in the wall of the stomach to modify the sensory motor nervous feedback and control in the wall.
17. The method of claim 10 wherein the biocompatible solution includes a biocompatible polymer and a biocompatible solvent.
18. The method of claim 17 wherein the biocompatible solution includes a contrast agent.
19. The method of claim 17 wherein the biocompatible solution of the biocompatible polymer and the biocompatible solvent has a composition comprising from about 2.5 to about 8.0 weight percent of a biocompatible polymer, from about 10 to about 40 weight percent of a water insoluble biocompatible contrast agent and from about 52 to about 87.5 weight percent of a biocompatible solvent.
