The fogarty catheter involved in this case was received by our product evaluation laboratory for a full analysis.The report of balloon burst was confirmed.The balloon was found to be ruptured, ruptured part was not returned.Both balloon windings were intact.Through lumen was patent without any leakage or occlusion.No other visible damage or abnormality was observed from catheter body or windings.Further investigation was performed by the engineers at the manufacturing site.A pra was already generated.Additionally, balloon and winding inspections are performed as part of the manufacturing process.The manufacturing records were reviewed and there is no indication of a related nonconformance; all process parameters were met and inspections passed successfully.The instructions for use (ifu) was reviewed and indicated that 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.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 part of this monthly review.
