Claim Text:
1. An apparatus for treating a body lumen, comprising: an elongate tubular member including a proximal end, a distal end sized for introduction into a body lumen, and a first inflation lumen extending between the proximal and distal ends; an inner balloon on the distal end formed from substantially inelastic material defining a central region, the inner balloon expandable from a delivery configuration in which the inner balloon is rolled or folded around the distal end, and an enlarged configuration in which the central region defines a substantially uniform diameter when inflation media is introduced into the first inflation lumen; an outer balloon on the distal end overlying the inner balloon, the outer balloon formed from elastic material such that the outer balloon expands elastically when the inner balloon is expanded from the contracted configuration to the enlarged configuration; and a plurality of stents disposed around an outer surface of the outer balloon and spaced apart from one another and aligned over the central region of the inner balloon.
