A magnet guided crossing system includes a first magnet that defines a first guide passage and a second magnet that defines a second guide passage, which are positioned in respective body structures. A crossing guide includes a catheter, a direction change piece and a magnetic latch in series that together define a third guide passage that extends from a proximal end of the catheter through a latching side of the magnetic latch. The poles of the first and second magnets and the magnetic latch are oriented so that the first and second magnets and the magnetic latch have a stable magnetically latched stack configuration. A puncture wire is slidably received in the catheter.
