Abstract
Abstract A tubular digestive screen for use in controlling the caloric intake of persons having morbid obesity is disclosed. The screen is made up of a thin-walled membrane-like tube, which has a firm ring at the top of the tube, a funnel-shaped portion below the firm ring, a tubular portion of constant diameter beginning below the funnel-shaped portion, and a distal end of the tube having a brush. The screen can be inserted and maintained in the digestive system of a patient without the need for an anchoring chain within the tube.
