Abstract:
A multi-layered balloon is provided where each layer is formed such that each layer is made from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, multi-layer balloon is provided with layers that allow for slipping, such that the balloon has a very high pressure rating and toughness, yet excellent folding characteristics. Methods for producing such multi-layer balloons using existing balloon forming equipment are also provided. The multi-layer balloons can have alternating structural and lubricating layers, or layers with low-friction surfaces. The multi-layer balloons are preferably manufactured using a variety of methods including nesting, co-extrusion, or a combination of nesting and co-extrusion. The multi-layer balloons have balloon layers having substantially similar, or the same, high degree of biaxial orientation of their polymer molecules such that each balloon layer of the multi-layer balloon will fail at approximately the same applied pressure.
