One fogarty embolectomy catheter was received by our product evaluation laboratory for a full examination.The report of "balloon burst" was confirmed.As received, balloon was found to be ruptured at central area.No other visible damage was observed from the catheter body and windings.Finally, through lumen was patent without any leakage or occlusion.Based on the available information that supports or confirms the failure mode, it cannot be determined that the failure is related to a manufacturing/design defect.As part of the manufacturing process, manufactured units go through a balloon inflation process performed as per procedure.However, complaints incidence will continue to be monitored, and applicable actions will be taken as required.The manufacturing records were reviewed and there is no indication of a related nonconformance; all process parameters were met, and inspections passed successfully.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".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.
