Abstract
A magnetic guide system for intubation of a tube into a patient's passageway. The system includes an intubation tube having a distal end sized for insertion into the patient. The tube includes a proximal end maintained external of the patient, and a flexible mid-portion allow lateral bending. A magnet member is enclosed on the distal end by a means for containment to allow rotation of the magnet member therein. The means for containment is composed of a material for passage of gases and liquids therethrough, while the magnet member is rotatable therein. The distal end and enclosed magnet member is insertable into a patient's passageway. Movement of the intubation tube distal end and rotating magnet member is influenced by movement of an external magnetic field from at least one magnet positioned external of the patient. A method for intubation of the intubation tube into a patient's passageway leading to a target organ is also disclosed.
