A feeding tube is configured for nasal insertion and advancement to the jejunum of a patient. The tube has a plurality of projections disposed along the surface of the distal tube portion for promoting advancement of the tube along the GI tract by peristaltic contractions. The tube includes first and second strings. The first string is aligned along the tube such that upon exertion of a pulling force on the first string, the distal end of the tube flexes in a direction of the force. The second string is aligned such that upon exertion of a pulling force on the second string, the tube is withdrawn from the GI tract responsive to the force. A snare may be provided for capturing the second string to promote withdrawal of the tube through the mouth of the patient. |
