1. A method for flaring a stent previously deployed within a branch body lumen including an ostium communicating with a main body lumen, a first end of the stent extending at least partially from the branch body lumen into the ostium, the method comprising:
providing an elongate member including a proximal end, a distal end, an expandable member carried on the distal end that includes a substantially uniform diameter distal section, and a proximal section extending proximally from the distal section, wherein at least the proximal section comprises compliant material molded to a shape in which the proximal section has a bulbous shape defining a first diameter and wherein the distal section has a substantially cylindrical shape defining a second diameter smaller than the first diameter;
introducing the distal end into the main body lumen;
positioning the distal end of the elongate member through the ostium and stent into the branch body lumen until the distal section is disposed within the stent;
initially expanding the expandable member to engage the distal section within the stent to substantially anchor the stent axially relative to the branch body lumen; and
expanding the proximal section to flare the first end of the stent within the ostium.
