A visual inspection was performed on the returned device.The reported balloon rupture, balloon separation and shaft separation were confirmed.The reported difficult to remove was unable to be confirmed due to the returned condition of the device.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.A review of the complaint history identified no other similar incidents and/or complaints reported from this lot.Balloon material ruptures can be affected by numerous factors such as balloon damage during processing, balloon material, inflation technique, inflation over rated burst pressure, interactions with other devices, lesion calcification and tortuosity, a previously implanted stent or insufficient preparation prior to use.The device was prepped prior to use with no leak or ruptures noted.Additionally, no balloon ruptured were reported during the first inflation to nominal pressure which would suggest that the device was not damaged prior to use.Follow-up with the account was conducted for information regarding the multiple sharp cuts on the balloon, inner member at the balloon location and multiple cuts on the shaft.No additional information was provided by the account.Based on the limited information provided, and returned analysis, the investigation was unable to determine a conclusive cause the reported difficulties.The noted bunching, kinks, wrinkles and stretching damaged on the device appear to be related to operation circumstances of the procedure, and likely occurred during the procedure and during packing for returned analysis.There is no indication of a product quality issue with respect to manufacture, design or labeling.Na.
