1. An apparatus for locating an ostium of a body lumen, comprising:
an elongate member comprising a proximal end, a distal end sized for introduction into a body lumen; and
first and second expandable members on the distal end of the elongate member, the first and second expandable members being independently expandable from one another between a contracted condition and an enlarged condition;
the second expandable member comprising proximal and distal ends attached to the distal end of the elongate member, the second expandable member comprising an intermediate portion expandable from a contracted condition to an enlarged condition having a substantially uniform diameter;
the first expandable member comprising a proximal end attached on the elongate member distal end adjacent the second expandable member proximal end, a proximal portion, a distal portion extending over the intermediate portion of the second expandable member, and a distal end attached to the elongate member adjacent the second expandable member distal end, the first expandable member formed from material to a predetermined shape in which the proximal portion has a substantially spherical shape when expanded from a contracted condition to an enlarged condition that includes a tapered distal surface extending transversely outwardly and proximally from the distal portion and the distal portion has a substantially cylindrical shape, the intermediate portion of the second expandable member expandable to a predetermined size in the enlarged condition that is smaller than the proximal portion in its enlarged condition.
