Block h6: problem code 4008 captures the reportable investigation result of balloon split.Block h10: investigation results: a visual examination of the returned complaint device found that the balloon was not folded which indicated that the device was subjected to positive pressure.A microscopic examination of the balloon found a balloon longitudinal tear located at the distal markerband and extending across the balloon material.No issues were noted on the balloon material, tip and the distal markerband.The rated burst pressure of the complaint device was 20 atmospheres as per nephromax ng specification.It was also noted that there were no kinks or damage to the shaft.This failure is likely due to factors or conditions related to the procedure during the use of the device, such as difficult patient anatomy that cold have caused the tear in the balloon material.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.A labeling review was performed and from the information available, this device was used per the instructions for use (ifu)/product label.
