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.
