Abstract
A magnetically guided device for insertion through a patient's nasal passageway of a tube for feeding or lavage of a target organ. The device includes a flexible tube having an insertion end sized for insertion through the patient's nasal cavity, pharynx and esophagus. The tube insertion end includes a magnetic member rotatably coupled to the insertion end and a porous tube segment spaced-apart proximal of the magnetic member. The magnetic member is rotatable within the insertion end and is responsive to an externally positioned magnetic field that is moved relative to the patient for guiding the insertion end through internal passageways and into the target organ within the patient. A method for insertion and positioning of a magnetically guided tube for feeding or for lavage of a target organ within a patient is also disclosed.
