A system for treating a bifurcated vessel comprises a first delivery catheter and a second delivery catheter. The first delivery catheter carries a first stent comprised of a proximal stent and a distal stent. The first delivery catheter also has a first elongate shaft, a proximal expandable member with the proximal stent disposed thereover, and a distal expandable member with the distal stent disposed thereover. The proximal and distal expandable members are independently expandable of one another. The second delivery catheter carries a second stent. The second delivery catheter also has a second elongate shaft, and a second expandable member with the second stent disposed thereover. The second expandable member is independently expandable of the proximal and the distal expandable members.
