Claim 16:
17. A method for expanding a prosthesis within a body lumen, comprising:
directing a distal end of an elongate member into a body lumen, the elongate member comprising:
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;

delivering a predetermined volume of inflation media into the first expandable member to expand the first expandable member; and
delivering a predetermined pressure of inflation media into the second expandable member to expand the second expandable member.
