1. A method of creating intravascular access, comprising:
manipulating a distal end of a device having a first alignment member to a location proximate to an inner wall of a primary vessel;
manipulating a guidewire having a second alignment member to a location proximate to an inner wall of a secondary vessel;
magnetically coupling the first alignment member of the distal end of the device and the second alignment member of the guidewire through the respective walls of the primary and secondary vessels, so that the device and guidewire are in close proximity and in alignment, and thereby pushing the primary and secondary vessels together; and
extending, after the step of magnetically coupling, a piercing member distally from the device, through the wall of the primary vessel, and through an adjacent wall of the secondary vessel, so that the end of the piercing member is disposed within the secondary vessel and thereby creating a communicating aperture on the opposing walls of the primary and secondary vessel,
contacting, during the step of extending the piercing member, the second alignment member with the piercing member to uncouple the magnetically coupled first and second alignment members and move both the second alignment member and the guidewire away from the distal end of the device.
