Our product evaluation lab received one 120403f catheter without any attached components.The customer report of the balloon of this fogarty catheter inflated eccentrically was not able to be confirmed due to balloon rupture.The balloon was found to be ruptured, and the spring tip was stretched and bent.After cutting the proximal side of balloon, ruptured edges appeared to match up.No visible damage was observed from both windings and catheter body.An engineering task was assigned to the manufacturing site for further investigation.A supplemental report will be forthcoming when the results become available.The lot number was not provided; therefore, a review of the manufacturing records could not be completed.Complaint histories for all reported events are reviewed against trending control limits, and any excursions above the control limits are assessed and documented as part of this monthly review.

It was reported that the balloon of this fogarty catheter inflated eccentrically during use.The balloon inflation was checked before use and no problem was found.However, after inserting the catheter into the patient, the catheter tip bent and the balloon did not inflate symmetrically.There were no patient complications reported.

The complaint was confirmed with objective evidence through the product evaluation.However, based on the available information there is no evidence that supports or confirms the failure mode is associated to a manufacturing/design defect that would have contributed to the reported event was identified.An in-depth investigation is not required since the failure is not confirmed to be associated to a manufacturing/design defect.As part of the manufacturing process, a general inspection of the catheter is performed in which, the units go through a general appearance and inflation inspection.In this inspection process, the catheter should not have bends, wrinkles, cuts, contamination, stain or discoloration or ripples.Also, the balloons windings are inspected for conditions such as loose windings, separation, contamination, slipped, defective, exposed shoulder and/or excessive adhesive.The instructions for use (ifu) indicates these warnings: 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.The possibility of balloon rupture must be taken into account when considering the risks involved in any embolectomy procedure.To minimize the risk of vessel damage, balloon rupture, or tip detachment, do not exceed the maximum recommended inflation volume and pull force for each size catheter.The amount of fluid in the syringe should be checked before each inflation.Do not exceed the recommended maximum inflation volume.With the catheter suitably positioned, inflate the balloon with sterile fluid or gas.Balloon inflation should be stopped when the balloon can be felt to engage the arterial wall.Inflation of the balloon is associated with a feeling of resistance to the fluid or gas injection.When no resistance is encountered it should be assumed that the balloon has ruptured.Discontinue inflation and remove the catheter at once.
