Abstract
One or more external magnets that are suitable for placement on the back or front of a patient's neck and methods for using the external magnet(s) to guide a feeding tube containing one or more internal magnets through the esophagus are described herein. The external magnet is applied to the back or the front of the patient's neck and the feeding tube is inserted into the patient's nose and advanced within the patient's body. The magnetic field of the external magnet combines with the magnetic field of the internal magnet to produce a sufficient magnetic force to pull or push the feeding tube apparatus against the posterior wall of the esophagus to prevent placement of the stylet in the patient's trachea or windpipe to prevent insertion into the patient's lungs.
