Patient demographics unable to be obtained.The lot number for this device was not supplied; therefore, further review of the related manufacturing records could not be performed.One fogarty catheter was received by our product evaluation laboratory for a full examination.Examination of the returned catheter found that the balloon was found to be ruptured in the middle area.Rupture edges did not appear to match up.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".Through lumen was patent without any leakage or occlusion.No other visible damage or abnormality was observed from catheter body or windings.An engineering investigation will be performed in order to consider any potential factors that may have contributed to this complaint.A supplemental report will be submitted accordingly upon investigation completion.

Added information to section h6 (type of investigation) updated section h6 (investigation findings) and h6 (investigations conclusions).Based on further engineering investigation, as part of the manufacturing process, the units go through a balloon inspection process including visual inspection in which the integrity of the catheter and balloon are validated.Also, a final inspection is performed.Additionally, as per specification for catheters produced by edwards lifesciences it is specified that the deterioration is a condition usually caused by age, excessive exposure to light, atmosphere, or ozone that appears on the balloon surface as a maze of fine cracks or crazing.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.
