Abstract

The present invention is directed to an apparatus and method for treating obesity. A tube is positioned that passes through a patient'"'"'s abdominal wall into the upper digestive system of the patient. The patient is allowed to carry out his/her everyday affairs including ingesting food. After the patient has ingested food, the food is extracted by pumping it out of the upper digestive system through the tube. The present invention is less invasive than current surgical procedures for reducing weight and allows patients to live a normal and active lifestyle without experiencing adverse side effects.

Claims

1. A method of achieving weight loss in a patient having an unobstructed gastrointestinal tract comprising the steps of:

(a) introducing a passageway into the patient'"'"'s stomach such that the passageway passes through the patient'"'"'s abdominal wall, the passageway having an outlet;

(b) allowing the patient to ingest food while the outlet is closed;

(c) opening the outlet to provide access to the patient'"'"'s stomach;

(d) extracting the food from the patient'"'"'s stomach through the passageway after the outlet has been opened;

(e) closing the outlet to block access to the patient'"'"'s stomach; and

(f) repeating steps (b) through (e) until the patient has lost at least 40 pounds.

2. The method of claim 1, wherein initiation of the extracting step occurs about 20 minutes after the patient has finished ingesting the food.

3. The method of claim 1, wherein the introducing step comprises positioning a tube that passes through the patient'"'"'s abdominal wall into the patient'"'"'s stomach.

4. The method of claim 1, wherein the food that has been extracted in step (d) is not reintroduced into the patient.

5. A method of limiting absorption of food in a patient having an unobstructed gastrointestinal tract comprising the steps of:

(a) introducing a passageway into the patient'"'"'s stomach such that the passageway passes through the patient'"'"'s abdominal wall, the passageway having an outlet;

(b) allowing the patient to ingest food while the outlet is closed;

(c) opening the outlet to provide access to the patient'"'"'s stomach;

(d) extracting the food from the patient'"'"'s stomach through the passageway after the outlet has been opened;

(e) closing the outlet to block access to the patient'"'"'s stomach; and

(f) keeping the tube in the patient for at least one month and repeating steps (b) through (e) at least 20 times to achieve weight loss in the patient.

6. The method of claim 5, wherein initiation of the extracting step occurs about 20 minutes after the patient has finished ingesting the food.

7. The method of claim 5, wherein the introducing step comprises positioning a tube that passes through the patient'"'"'s abdominal wall into the patient'"'"'s stomach.

8. The method of claim 5, wherein the food that has been extracted in step (d) is not reintroduced into the patient.

9. A method of achieving weight loss in a person having an unobstructed gastrointestinal tract and having a passageway into the person'"'"'s stomach that passes through the person'"'"'s abdominal wall, the passageway having an outlet, the method comprising the steps of:

(a) ingesting food while the outlet is closed;

(b) opening the outlet to provide access to the person'"'"'s stomach;

(c) extracting the food from the person'"'"'s stomach through the passageway after the outlet has been opened;

(d) closing the outlet to block access to the person'"'"'s stomach; and

(e) repeating steps (a) through (d) until the person has lost at least 40 pounds.

10. The method of claim 9, wherein initiation of the extracting step occurs about 20 minutes after the person has finished ingesting the food.

11. The method of claim 9, wherein the food that has been extracted in step (c) is not reintroduced into the person.

12. A method of limiting absorption of food in a person having an unobstructed gastrointestinal tract and having a passageway into the person'"'"'s stomach that passes through the person'"'"'s abdominal wall, the passageway having an outlet, the method comprising the steps of:

(a) ingesting food while the outlet is closed;

(b) opening the outlet to provide access to the person'"'"'s stomach;

(c) extracting the food from the person'"'"'s stomach through the passageway after the outlet has been opened;

(d) closing the outlet to block access to the person'"'"'s stomach; and

(e) repeating steps (a) through (d) at least 20 times to achieve weight loss.

13. The method of claim 12, wherein initiation of the extracting step occurs about 20 minutes after the person has finished ingesting the food.

14. The method of claim 12, wherein the food that has been extracted in step (c) is not reintroduced into the person.
