Abstract

Apparatus and methods are described for treatment of morbid obesity using minimally invasive techniques. The apparatus includes a system of components that may be used separately or in combination for effectively reducing stomach volume, bypassing a portion of the stomach and/or small intestines, reducing nutrient absorption in the stomach and/or small intestines and/or depositing minimally or undigested food farther than normal into the intestines, thereby stimulating intestinal responses. The components described include a gastric sleeve device, an intestinal sleeve device, and a combined gastrointestinal sleeve device.

Claims

1. Cancelled

2. A method of treating a patient, comprising the steps of:

providing a gastrointestinal sleeve device having an elongate tubular body, with a proximal end and a distal end; and

positioning the gastrointestinal sleeve device in the patient'"'"'s digestive tract such that the proximal end of the tubular body is positioned in the vicinity of the gastroesophageal junction to receive ingested food and liquids from the patient'"'"'s esophagus and the distal end of the tubular body is positioned in the patient'"'"'s intestine.

3. A method of treating a patient as in claim 2, further comprising the step of attaching the proximal end of the tubular body to the patient in the vicinity of the gastroesophageal junction.

4. A method of treating as in claim 3, wherein the attaching step comprises using a suture.

5. A method of treating a patient as in claim 3, wherein the attaching step comprises suturing the tubular body to the wall of the digestive tract in the vicinity of the gastroesophageal junction.

6. A method of treating a patient as in claim 2, wherein at least a portion of a wall of the tubular body is porous.

7. A method of treating a patient as in claim 2, wherein the tubular body is impermeable such that the tubular body acts as a internal intestinal bypass.

8. A method of treating a patient as in claim 2, wherein the providing step comprises providing the tubular body with a funnel opening on the proximal end.

9. A method of treating a patient as in claim 2, wherein the positioning step comprises positioning the tubular body such that the distal end is positioned in the patient'"'"'s jejunum.

10. A method of treating a patient as in claim 2, wherein the positioning step comprises positioning the tubular body such that the distal end is positioned in the patient'"'"'s ileum.

11. A method of treating a patient, comprising the steps of:

providing a tubular sleeve, having a proximal end, a distal end and a lumen extending therethrough;

positioning the proximal end in the stomach and the distal end in the intestine; and

preventing gastric juices expressed from the wall of the stomach distally of the proximal end from entering the lumen.

12. A method of treating a patient as in claim 11, wherein the positioning step comprises positioning the distal end in the jejunum.

13. A method of treating a patient as in claim 11, wherein the providing step comprises providing a sleeve having a substantially constant diameter throughout its length.

14. A method of treating a patient as in claim 11, wherein the providing step comprises providing a sleeve having a funnel-shaped entry on the proximal end.

15. A method of treating a patient as in claim 11, wherein the providing step comprises providing a tube with a stoma.
