One 120404f catheter with stylet was returned for evaluation.The reported event of catheter was broken off was confirmed.As received the catheter body was found completely broken at 1.5cm distal from the tip.The tip of catheter was returned.Broken sections appeared straight and even and matched up.Proximal windings were found unraveled.The balloon and distal windings were intact.There was no other visible damage observed from the catheter body or stylet.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.A device history record review was completed and documented that device met all specifications upon distribution.An engineering evaluation was initiated to assess for any manufacturing related processes which could be correlated to the complaint.Based on the available information there is no evidence that supports or confirms the failure mode is associated to a manufacturing/design defect.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.Corrected data: updates to the h6 codes are as follows: type of investigation was changed to testing of actual/suspected device, historical data analysis, communication/interviews investigation findings was changed to no findings available.Investigation conclusions was changed to cause not established.
