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.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
