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.

La présente invention fait état d'une méthode et d'un appareil d'intubation duodénale d'un patient. Il s'agit de générer un couple de forces entre un aimant permanent placé sur l'extrémité d'un cathéter et un aimant permanent portatif. Le couple de forces est suffisamment important pour appliquer une force de traction sur l'extrémité du cathéter en vue de le déplacer dans l'estomac, dans la direction du bol alimentaire, au-delà du sphincter pylorique et jusque dans le duodénum. Les deux aimants présentent un puissant champ de flux magnétique formé au moyen de néodyme, de fer, de bore et de dysprosium. L'aimant portatif est dimensionnée afin que la personne effectuant l'intubation puisse le saisir entre ses doigts ouverts.
