Additional Manufacturer Narrative

The manufacturing records were reviewed for the lot involved and there is no indication of a related nonconformance.All process parameters were met and inspections passed successfully.One fogarty embolectomy catheter was received by our product evaluation laboratory for a full examination.The report of "balloon was found to be ruptured" was confirmed.As received, the balloon was found to be ruptured at central area.Latex edges did not appear to match at the ruptured location.Both windings were intact.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.See specification table".On the other hand, through lumen was patent without any leakage or occlusion.No other visible damage or abnormality was observed from catheter body or windings.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.
