Claim 10:
11. 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, a first lumen extending from a first port on the proximal end to the distal end, and a second lumen extending from a second port on the proximal end to the distal end; and
a first balloon on the distal end of the elongate member formed from compliant material and having an interior communicating with first lumen;
a second balloon on the distal end of the elongate member formed from non-compliant material and having an interior communicating with the second lumen such that the first and second balloons are independently expandable from one another between a contracted condition and an enlarged condition;
the second balloon comprising proximal and distal ends attached to the distal end of the elongate member, the second balloon comprising an intermediate portion defining a substantially uniform diameter in the enlarged condition;
the first balloon comprising a proximal end attached on the elongate member distal end adjacent the second balloon proximal end, a proximal portion, a distal portion extending over the intermediate portion of the second balloon, and a distal end attached to the elongate member adjacent the second balloon distal end, the first expandable member formed to a predetermined shape in which the proximal portion has a substantially spherical shape when expanded from the contracted condition to the 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 balloon expandable to a predetermined size in the enlarged condition that is smaller than the proximal portion in its enlarged condition.
