1. A stent delivery system comprising:
- a catheter having a proximal end and a distal end;
a first balloon arrangement coupled to the catheter adjacent the distal end of the catheter, the first balloon arrangement including a main vessel balloon;
a second balloon arrangement coupled to the catheter adjacent the first balloon arrangement, the second balloon arrangement including a branch vessel balloon and an inflation lumen, the branch vessel balloon having an accordion configuration that is expandable along a longitudinal axis from a collapsed configuration to an expanded configuration, the longitudinal axis extending radially away from the inflation lumen.

Abstract
Apparatus and method are provided for treatment of a bifurcation of a body lumen. The apparatus includes an elongated catheter body having a proximal end and a distal end. A balloon is associated with the distal end of the balloon catheter. The balloon includes a main vessel balloon for treating a main vessel of the bifurcation, and a branch vessel balloon for treating a branch vessel of the bifurcation. The branch vessel balloon includes an accordion configuration capable of being expanded from an unexpanded collapsed accordion configuration to an expanded accordion configuration extending into the branch vessel.
