  • METHODS OF MANUFACTURING NESTED BALLOONS UTILIZING PRESSURIZED CONSTRAINED ANNEALING
    Publication number: 20220161008
    Abstract: A nested balloon is provided where each balloon is formed from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, nested 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 nested balloons using existing balloon forming equipment are also provided. The nested balloons can have layers with low-friction surfaces. The nested balloons are preferably manufactured using a variety of methods, including pressurized constrained annealing.
    Type: Application
