摘要： A feeding tube for insertion into a digestive system of a subject includes a tube having a distal end and a proximal end. The tube defines a lumen extending from the proximal end to the distal end. The lumen has an inner diameter sized to accommodate the passage of alimentation to the digestive system of the subject. The distal end is arranged to be positioned through the subject's esophagus and into the digestive system of the subject. An expandable member is disposed at the distal end. The expandable member is expandable to an outer diameter that is larger than an inner diameter of the subject's respiratory tract to prevent insertion of said lumen therein.
