Abstract
A balloon catheter includes a first balloon positioned inside of a second balloon, both of which are mounted about a catheter and fluidly connected to respective inflation lumens. In a first inflated configuration, the second balloon is inflated and has a shape that includes a plurality of bulb segments, with each two consecutive bulb segments being separated by a waist hoop. In a second inflated configuration both the inner and outer balloons are inflated, and the inner balloon bears radially outwardly against the waist hoop of the outer balloon such that the waist hoop of the outer balloon has a larger diameter in the second inflated configuration than in the first inflated configuration. The bulb segment separated by waist hoops enable the balloon catheter to conform to curved passageways, such as during the implementation of a stent.
