143. A method for treating obesity of a patient using at least one operable stretching device implantable in the patient, the method comprising:

automatically controlling the operable stretching device, when implanted, using an implantable control unit to stretch the stomach wall portion of the patient'"'"'s stomach wall in connection with the patient eating, such that satiety is created, wherein controlling the operable stretching device comprises controlling;

force used for stretching the stomach wall portion,

time periods the stretching is applied, and

what causes the stretching to be applied.

144. The method according to claim 143, further comprising the initial steps of:

cutting the skin of the patient,

inserting a dissecting tool and dissecting an area of the stomach wall of the patient, and at least one of the steps of;

placing the operable stretching device in connection with the stomach wall by invaginating the stretching device in the stomach wall, with stomach to stomach sutures or staplers,

placing an operable stretching device comprising two parts adapted to engage different parts of the stomach wall, by suturing or stapling a first part to a first area of the stomach wall, and suturing or stapling a second part to a second area of the stomach wall, such that the operable stretching device can stretch the stomach wall by moving the first and second areas away from each other.

145. The method according to claim 144, wherein the method steps of cutting the skin of the patient and inserting a dissecting tool and dissecting an area of the stomach wall comprises the steps of:

inserting a needle like tube into a cavity of the patient'"'"'s body,

using the needle like tube to fill the cavity with gas thereby expanding the cavity,

placing at least two trocars in the patient'"'"'s body,

inserting a camera through one of the trocars into the cavity,

inserting a dissecting tool through one of the trocars and dissecting an area of the stomach wall.

146. The method according to claim 144, wherein the operable stretching device comprises three or more parts engaged with different parts of the stomach wall, and wherein the method further comprises the step of fixating a first part to a first area of the stomach wall, fixating a second part to a second area of the stomach wall and fixating a third part to a third area of the stomach wall, such that at least one of:

the area between the first and second parts,

the area between the second a third parts, and

the area between the first and third parts can be stretched independently from each other.

147. The device according to claim 144, further comprising the step of implanting the implantable control unit in the body of the patient.

148. The method according to claim 147, further comprising the step of implanting at least one sensor for sensing a physical parameter of the patient or a functional parameter of the stretching device, and connecting the sensor to the implantable control unit.

149. The method according to claim 148, wherein the step of implanting a sensor comprises implanting a sensor adapted to sense the patient eating, and wherein the method further comprises the step of controlling the operable stretching device on the basis of the patent eating.

150. The method according to claim 148, wherein the step of implanting at least one sensor comprises implanting a sensor adapted to sense a parameter selected from a group consisting of:

contraction and relaxation of the Cardia or esophagus, esophagus movement, esophagus bending, esophagus motility, esophagus stretching, esophagus pressure, food passing esophagus, food in the stomach, neural activity, vagus activity, muscle activity, hormonal activity, stomach motility, stomach stretching, stomach pressure, stomach bending, stomach filling, and acidity in the stomach, capacitance, resistance, volt, ampere, light absorption or visualization, ultrasound reflection or absorption, bending metal, bimetal and PH.

151. The method according to claim 144, further comprising fixating a second operable stretching device to the stomach wall, for stretching a second area of stomach wall of the patient.

152. The method according to claim 151, further comprising controlling the first stretching device, during a first time period, to stretch a first portion of the stomach wall, and controlling the second stretching device during a second time period, to stretch a second portion of the stomach wall different from said first portion of the stomach, to allow longer relaxation of the stomach wall in between stretching periods.

153. The method according to claim 144, further comprising the step of implanting at least one of an internal energy source and a wireless energy receiver for non-invasively energizing the operable stretching device.

154. The method according to claim 143, further comprising the initial steps of:

inserting a gastroscope through the esophagus of the patient,

inserting a dissecting tool through the gastroscope and dissecting an area of the stomach wall of the patient, and at least one of the steps of;

placing the operable stretching device in connection with the stomach wall by invaginating the stretching device in the stomach wall, with stomach to stomach sutures or staplers,

placing an operable stretching device comprising two parts adapted to engage different parts of the stomach wall, by suturing or stapling a first part to a first area of the stomach wall, and suturing or stapling a second part to a second area of the stomach wall, such that the operable stretching device can stretch the stomach wall by moving the first and second areas away from each other.

155. The method according to claim 154, wherein the operable stretching device comprises three or more parts adapted to engage different parts of the stomach wall, and wherein the method further comprises the step of fixating a first part to a first area of the stomach wall, fixating a second part to a second area of the stomach wall and fixating a third part to a third area of the stomach wall, such that at least one of:

the area between the first and second parts,

the area between the second a third parts, and

the area between the first and third parts can be stretched independently from each other.

156. The device according to claim 154, further comprising the step of implanting the implantable control unit in the body of the patient.

157. The method according to claim 156, further comprising the step of implanting at least one sensor for sensing a physical parameter of the patient or a functional parameter of the stretching device, and connecting the sensor to the implantable control unit.

158. The method according to claim 157, wherein the step of implanting a sensor comprises implanting a sensor adapted to sense the patient eating, and wherein the method further comprises the step of controlling the operable stretching device on the basis of the patent eating.

159. The method according to claim 157, wherein the step of implanting at least one sensor comprises implanting a sensor adapted to sense a parameter selected from a group consisting of:

contraction and relaxation of the Cardia or esophagus, esophagus movement, esophagus bending, esophagus motility, esophagus stretching, esophagus pressure, food passing esophagus, food in the stomach, neural activity, vagus activity, muscle activity, hormonal activity, stomach motility, stomach stretching, stomach pressure, stomach bending, stomach filling, and acidity in the stomach, capacitance, resistance, volt, ampere, light absorption or visualization, ultrasound reflection or absorption, bending metal, bimetal and PH.

160. The method according to claim 154, further comprising fixating a second operable stretching device to the stomach wall, for stretching a second area of stomach wall of the patient.

161. The method according to claim 160, further comprising controlling the first stretching device, during a first time period, to stretch a first portion of the stomach wall, and controlling the second stretching device during a second time period, to stretch a second portion of the stomach wall different from said first portion of the stomach, to allow longer relaxation of the stomach wall in between stretching periods.

162. The method according to claim 154, further comprising the step of implanting at least one of an internal energy source and a wireless energy receiver for non-invasively energizing the operable stretching device.
