Zusammenfassung:	A catheter system includes a balloon dilation catheter. The balloon dilation catheter includes an elongate shaft, an expandable dilation balloon, and an expandable stop element. The elongate shaft has a dilation balloon lumen that is configured to couple with a first fluid supply. The expandable dilation balloon is coupled to the elongate shaft and is fluidly connected to the dilation balloon lumen. The expandable dilation balloon is configured to transition between an inflated state and a non-inflated state. The expandable stop element is distal to the expandable dilation balloon. The expandable stop element is configured to transition between an expanded state and a non-expanded state. The expanded dilation balloon is configured to define a larger outer diameter in the inflated state than an outer diameter defined by the expandable stop element in the expanded state.
