A probe for use in an anatomical region of a patient. The probe can optionally include: a proximal portion; an insertion portion and a magnetizable element. The insertion portion can be coupled to the proximal portion and can extend distally thereof. The insertion portion can have an elongated extent and a longitudinal axis. The insertion portion can include a flexible section. The magnetizable element can be positioned at a distal end portion of the insertion portion and can be configured for use within the anatomical region to produce a magnetic force between the magnetizable element and an extracorporeal magnetizable element that can direct the distal end portion of the probe to a desired location within the anatomic region.
