1. A catheter assembly, comprising:

  • a first catheter branch having a distal end portion, the distal end portion of the first catheter branch extending in a first direction;

    a second catheter branch having a distal end portion, the distal end portion of the second catheter branch extending in a second direction that is generally the same direction as the first direction;

    wherein the first and second catheter branches are secured together at a proximal location and the distal end portions of the first and second catheter branches are free to twist around each other along a longitudinal axis of the catheter assembly;

    a first distal marker and a first proximal marker positioned on the first catheter branch, the first distal marker and the first proximal marker each having a distal portion and a proximal portion;

    a second distal marker and a second proximal marker positioned on the second catheter branch, the second distal marker and the second proximal marker each having a distal portion and a proximal portion, when the first catheter branch and the second catheter branch are in an untwisted configuration, the distal portion of the first proximal marker is positioned proximal of the proximal portion of the second proximal marker and the proximal portion of the first distal marker is positioned distal of the distal portion of the second distal marker; and

    when the first catheter branch and the second catheter branch are in a twisted configuration such that the first catheter branch and the second catheter branch are twisted around one another along a longitudinal axis of the catheter assembly, the proximal portion of the first distal marker is positioned proximal of the distal portion of the second distal marker.
