A product evaluation was completed on the returned 12tlw804f catheter.The reported event of ruptured was confirmed.Balloon did not inflate due to a rupture at the central area.The edges of latex did not match at the rupture location.Through lumen was patent without any leakage or occlusion.No other visible damage or abnormality was observed from catheter body.Per the ifu, "balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures." and "to minimize the risk of vessel damage, balloon rupture, or tip detachment, do not exceed the maximum recommended inflation and pull force for each size catheter".No other visible damage was observed from the catheter body and windings.Through lumen was patent without any leakage or occlusion.An engineering evaluation was initiated to assess for any manufacturing related processes which could be correlated to the complaint.A device history record review was completed and documented that device met all specifications upon distribution.Based on the available information there is no evidence that supports or confirms the failure mode is associated to a manufacturing or design defect.The controls to defect the failure mode are established in the manufacturing process.As part of the manufacturing process, 100% of the manufactured units go through a balloon inflation process.A corrective action is not required at this time.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.
