  • positioning only a single retriever in a collapsed position, the obstruction retriever having an obstruction engaging portion extending from an insertion element, the obstruction engaging portion being an elongate element which extends from the insertion element to a free end which is free of any fixed attachment to any other member, the obstruction retriever having substantially only one filament said filament extending to the free end, the obstruction engaging portion being movable from a collapsed position to an expanded position, the obstruction engaging portion being naturally biased toward the expanded position;

    advancing the obstruction retriever through an obstruction in the collapsed position until at least the free end of the obstruction engaging portion is beyond the obstruction;

    moving the obstruction engaging portion so that the obstruction becomes ensnared in the obstruction engaging portion; and
