A stent delivery system for deployment at a bifurcated vessel includes a catheter and a balloon. The length of the balloon is defined by a proximal balloon region and a distal balloon region. The proximal balloon region is disposed about a first longitudinal axis and the distal balloon region is disposed about a second longitudinal axis. The balloon has an unexpanded state and an expanded state, and a bend along its length. The proximal balloon region intersects the distal balloon region at the bend. In both the unexpanded state and the expanded state, at least one of the first longitudinal axis and the second longitudinal axis define an oblique angle relative to the main vessel longitudinal axis.
