Abstract
A method and apparatus for duodenal intubation of a patient is provided by establishing a force couple between a permanent magnet in the catheter tip and a hand held permanent magnet. The force couple is sufficiently great to impart a traction force to the catheter tip for advancing movement in the direction of bolus in the stomach beyond the pyloric sphincter and into the duodenum. Both magnets have an intense field of magnetic flux as formed by neodymium, iron, boron and dysprosium. The hand held magnet is of a size that can be grasped between the outstretched figures of a person performing the intubation procedure.
