ABSTRACT:
A magnetic retrieval catheter for retrieving a magnetically attractable object such as a disk-shaped battery from the stomach of a patient. The catheter includes an elongated member tube with a neodymium-based rare-earth magnet positioned in the passageway of the tube about the distal end thereof. The elongated member tube comprises a pliable, flexible material such as polyvinylchloride. A compatible polyvinylchloride dispersion coating material surrounds the distal end of the tube and the distal portion of the magnet extending from the passageway of the tube for securing the magnet in the passageway of the tube and for minimizing oxidation of the rare-earth magnet. A handle is attached about the proximal end of the tube for the manipulation of the tube by the physician. A guide is also provided for insertion through the handle and in the tube passageway about the distal end for controlling and advancing the tube.
