## 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

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the first retention member is configured so that a position of the first retention member with respect to the gastrostomy tube is adjustable to accommodate a change in an amount of intervening tissue between the patient's stomach and the patient's abdomen.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising a second retention member attached to the gastrostomy tube, wherein the second retention member is attached to an opposite side of the patient's abdominal wall from the first retention member.

### Claim 6 (depends on 5)

The apparatus of claim 5, the second retention member being inflatable.

### Claim 7 (depends on 5)

The apparatus of claim 5, the second retention member being non-inflatable.

### Claim 8 (depends on 5)

The apparatus of claim 5, wherein the first retention member is configured so that a position of the first retention member with respect to the second retention member is adjustable to accommodate a change in an amount of intervening tissue between the patient's stomach and the patient's abdomen.

### Claim 9 (depends on 5)

The apparatus of claim 5, wherein the distance between the second retention member and the first retention member is adjustable to accommodate a change in an amount of intervening tissue between the patient's stomach and the patient's abdomen.

### Claim 10 (depends on 1)

The apparatus of claim 1, wherein the holes are located on the tubular sidewall in a spiral pattern.

### Claim 11 (depends on 1)

The apparatus of claim 1, wherein the holes are about 5×7 mm in size.

### Claim 12 (depends on 1)

The apparatus of claim 1, wherein the holes are spaced about 1 to 1.5 cm apart.

### Claim 13 (depends on 1)

The apparatus of claim 1, wherein the distal end portion of the tube is at least 10 cm long.

### Claim 14 (depends on 1)

The apparatus of claim 1, further comprising a pump that is attachable or permanently attached to the tube for removing food from the upper digestive system of the patient.

### Claim 15 (depends on 14)

The apparatus of claim 14, wherein the pump periodically operates in a reverse direction.

### Claim 16 (depends on 14)

The apparatus of claim 14, wherein the tube further comprises a luer lock configured so that the pump is attachable or permanently attached to the tube's outer surface.

The apparatus of claim 1, further comprising an inflatable balloon attached to the distal end portion of the tube.

### Claim 18 (depends on 1)

The apparatus of claim 1, further comprising a valve configured to permit removal of food from the stomach through the tube and to prevent matter from entering the stomach through the tube.

### Claim 19
