Abstract

A first part of the inventive instrument comprises an insertion and removal device in the form of a catheter which may be inserted through the mouth, pharynx, and esophagus into the stomach. The catheter includes an outer sheath which protects the human body while a tool extending coaxially through an inner sheath is being manipulated. The tool includes a remotely operated pair of tweezers for holding or releasing a loop on insertion or seizing and holding the loop on removal of the second part of the inventive instrument. The second part of the instrument comprises a tube for implantation in the small intestine. While it is so implanted, the tube prevents food from being there absorbed by the body. The tube may be used to treat obesity or alcoholism, or to cover an ulcer and give it an opportunity to heal without exposure to digesting food.
