Claim 2
Independent Claim
53 words
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 comprising the step of forming at least one implant in the wall in the vicinity of the pyloric sphincter to inhibit emptying of the stomach.
Claim 3
Dependent Claim
27 words
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.
Claim 4
Dependent Claim
29 words
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.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein the wall has a muscle layer, the at least one implant being formed in the muscle layer of the wall.
Claim 6
Dependent Claim
11 words
The method of claim 1 wherein the implant is arcuate shaped.
Claim 7
Dependent Claim
23 words
The method of claim 1 further comprising the step of inhibiting the ability of the stomach to expand so as to prolong satiety.
Claim 8
Dependent Claim
31 words
The method of claim 6 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.
Claim 9
Independent Claim
54 words
A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a stomach formed by a wall comprising the step of introducing a solution into the wall of the stomach to form at least one implant in the wall so as to provoke longer periods of satiety.
Claim 10
Independent Claim
54 words
A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a stomach formed by a wall comprising the step of introducing a solution into the wall of the stomach to form at least one implant in the wall so as to provoke longer periods of satiety.
Claim 11
Dependent Claim
24 words
The method of claim 8 wherein the introducing step includes the step of forming a plurality of implants in the wall of the stomach.
Claim 12
Dependent Claim
17 words
The method of claim 9 wherein the plurality of implants extend across a portion of the stomach.
Claim 13
Dependent Claim
14 words
The method of claim 9 wherein the plurality of implants extend around the stomach.
Claim 14
Dependent Claim
26 words
The method of claim 8 wherein the wall has a muscle layer, the at least one implant being formed in the muscle layer of the wall.
Claim 15
Dependent Claim
31 words
The method of claim 8 wherein the introducing step includes the step of forming at least one implant in the wall of the stomach to decrease the contractility of the wall.
Claim 16
Dependent Claim
36 words
The method of claim 8 wherein the introducing 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.
Claim 17
Independent Claim
54 words
A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a lower esophageal sphincter and a stomach formed by a wall comprising the step of forming an antireflux barrier in the stomach that is secondary to the lower esophageal sphincter for inhibiting reflux from the stomach.
Claim 18
Independent Claim
54 words
A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a lower esophageal sphincter and a stomach formed by a wall comprising the step of forming an antireflux barrier in the stomach that is secondary to the lower esophageal sphincter for inhibiting reflux from the stomach.
Claim 19
Dependent Claim
20 words
The method of claim 15 wherein the forming step includes the step of making a secondary sphincter in the stomach.
Claim 20
Dependent Claim
35 words
The method of claim 16 wherein the forming step includes the step of creating first and second spaced-apart artificial walls extending through the stomach from the lower esophageal sphincter to at least the secondary sphincter.
Claim 21
Dependent Claim
33 words
The method of claim 17 wherein the creating step includes the step of creating the first artificial wall across a portion of the stomach to exclude a portion of the stomach from use.
Claim 22
Dependent Claim
28 words
The method of claim 17 wherein the making step includes the step of forming at least one implant in the wall between the first and second artificial walls.
Claim 23
Dependent Claim
29 words
The method of claim 19 wherein the making step includes the step of forming a plurality of circumferentially-disposed implants in the wall between the first and second artificial walls.
Claim 24
Dependent Claim
26 words
The method of claim 19 wherein the wall has a muscle layer, the at least one implant being formed in the muscle layer of the wall.
Claim 25
Dependent Claim
32 words
The method of claim 15 further comprising the step of forming at least one implant in the wall in the vicinity of the lower esophageal sphincter to enhance the lower esophageal sphincter.
Claim 26
Independent Claim
71 words
A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a lower esophageal sphincter and a stomach formed by a wall, the stomach having a volume, comprising the steps of partitioning the stomach to reduce the volume of the stomach and forming at least one implant in the wall in the vicinity of the lower esophageal sphincter to enhance the lower esophageal sphincter.
Claim 27
Independent Claim
71 words
A method for treating morbid obesity in a body of a mammal having a gastrointestinal tract extending through a lower esophageal sphincter and a stomach formed by a wall, the stomach having a volume, comprising the steps of partitioning the stomach to reduce the volume of the stomach and forming at least one implant in the wall in the vicinity of the lower esophageal sphincter to enhance the lower esophageal sphincter.
