METHOD OF MAGNETICALLY NAVIGATING MEDICAL DEVICES WITH MAGNETIC FIELDS AND GRADIENTS, AND MEDICAL DEVICES ADAPTED THEREFOR

摘要

A method for applying an elongate magnetic element (20) to the surface of an internal body structure includes applying a magnetic field to the elongate magnetic element to orient the elongate magnetic element in a selected orientation, and applying a magnetic gradient to the elongate magnetic element to draw the elongate magnetic element against the surface of the body structure.
