Abstract
A balloon is disclosed that has two differing rates of distensibility. It can be used to perform angioplasty by taking advantage of its high strength and relatively low distensibility up to a predetermined range of pressure and still be used to set a stent by operating a pressure range where there is a higher distensibility. the balloon can be of a single material that is oriented less than fully or a blend of materials similarly oriented. In another embodiment, strands of a more crystalline material run longitudinally through a matrix of a less crystalline material, with the resulting balloon, when not fully biaxially oriented, exhibiting high burst strength and two different rates of distension at different applied inflation pressures.
