Abstract
A magnetic intubation apparatus insertable into an opening in a patient for guiding a tube into a preferred passageway within the patient. The magnetic intubation apparatus includes a flexible elongated body having an insertion end sized to be inserted through the patient's internal passageways. A magnetic member is coupled to the insertion end in a pivotable relationship. During insertion into the patient, the insertion end having the magnetic member thereon is guided into a preferred passageway such as the trachea or the esophagus by manipulating an external magnetic field disposed proximal to the patient. A method for insertion is also disclosed, providing for positioning within a patient of an elongated body having a magnetic member coupled to an insertion end that is guided by an external magnetic field into the preferred passageway within the patient for intubation of a tube into the preferred passageway.
