The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.There was no leak noted during preparation, which suggests a product quality issue did not contribute to the reported difficulties.The investigation determined the reported complaint appears to be related to operational context.In this case, it is likely that the balloon interacted with the heavily calcified and tortuous anatomy such that the balloon became damaged and subsequently ruptured during inflation.Additionally, the reported difficult advancing and removing the device likely result from the balloon dilatation catheter (bdc) interacting with the challenging anatomy.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.
