1. An apparatus comprising:
- a. a tube comprisingi. a distal end portion having a sidewall with a plurality of holes located therein, wherein said distal end portion is configured to be disposed in an upper digestive system of a patient; and
ii. a proximal end portion that is configured to pass through the patient'"'"'s abdominal wall when the distal end portion of the tube is disposed in the upper digestive system of the patient; and
b. a first retention member that is disposed on the distal portion of the gastrostomy tube and attached to the tube to prevent dislodgement of the tube, wherein the first retention member is configured with respect to the tube so that the proximal end portion of the tube will lie substantially flush with the patient'"'"'s abdominal surface when the distal end portion of the tube is disposed in the upper digestive system of the patient, and wherein the first retention member is configured with respect to the tube so that a position of the retention member is adjustable with respect to the tube to accommodate changes in thickness of the abdominal wall.

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.

30. A method for resizing a gastrostomy tube placed through a patient'"'"'s abdominal wall to accommodate a reduction in an amount of tissue in the patient'"'"'s abdominal wall comprising:
- moving a retention member attached to a proximal end portion of the gastrostomy tube towards the patient'"'"'s abdomen; and
cutting off the proximal end portion of the gastrostomy tube.
- moving a retention member attached to a proximal end portion of the gastrostomy tube towards the patient'"'"'s abdomen; and
-
31. A method for placing a gastrostomy tube through a patient'"'"'s abdominal wall, wherein the gastrostomy tube comprises a tubular sidewall, a distal end portion, and a proximal end portion, comprising:
-
visualizing an insertion site on the patient'"'"'s abdomen; making an incision at the insertion site; inserting a cannula through the incision; inserting a guide wire comprising a proximal end and a distal end through the cannula, such that the distal end of the guide wire is inserted into the patient'"'"'s stomach and the proximal end of the guide wire extends out of the patient'"'"'s abdomen; pulling the distal end of the guidewire from the patient'"'"'s stomach and out of the patient'"'"'s mouth;
attaching the proximal end portion of the gastrostomy tube to the distal end of the guide wire;pulling the proximal end portion of the gastrostomy tube through the incision by pulling the proximal end of the guide wire;
cutting the gastrostomy tube so that the proximal end portion of the gastrostomy tube is substantially flush with the patient'"'"'s abdomen; andattaching a second retention member to the proximal end portion of the gastrostomy tube so that the second retention member lies substantially flush with the patient'"'"'s abdomen. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
