Abstract
A system and method for gaining access to an internal bodily structure, such as the ampullae. The system includes an elongate catheter having a lumen extending there through. An elongate wire including a distal coil is movably extendable from the distal end of the catheter and is configured to engage the inner surface of the bodily structure. Proximal movement of the elongate wire flattens the inner surface of the bodily structure and aligns the passageway thereof with the longitudinal axis of the catheter.
