Abstract
An axial multi-chamber angioplasty balloon assembly for insertion into a blood vessel comprises a primary elongated, elastic, inflatable balloon having a first Young's Modulus, a distal portion, a proximal portion and an intermediate portion having a first diameter therebetween, defining a first chamber; a secondary elongated, elastic, inflatable balloon having a second Young's modulus, a distal portion, a proximal portion and an intermediate portion having a second diameter therebetween, defining a second chamber; the intermediate portions of the primary and the secondary balloons being attached in common; wherein the first and the second chambers define a variable dilation device for dilating an anatomical stricture having a first diameter-pressure characteristic curve defined by the primary balloon's Young's modulus, a second diameter-pressure characteristic curve defined by the secondary balloon's Young's modulus and a third diameter-pressure characteristic curve defined by the combined Young's modulus of the primary and secondary balloons.
