Balloon Cyclic Fatigue
Balloons must withstand multiple inflations during clinical use to avoid inducing device failure or vessel damage.
Tested balloons that are not constrained by any test fixture or device are inflated in incremental steps to defined target pressure. Pressure is held for a specific interval of time. Balloons are repeatedly deflated and inflated to the target pressure for a total of multiple cycles. Any loss of pressure, due to failure of the balloon, shaft, or proximal or distal seals is reported as a test failure.
The test is performed with an automatic inflation/deflation system.
