The device was returned for analysis.The reported material separation was able to be confirmed.The reported difficult to insert was unable to be replicated in a testing environment due to the condition of the returned device.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history did not indicate a lot specific quality issue.As there was no reported damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that during insertion the guide wire was not coaxially aligned resulting in interaction with the insertion aid; thus resulting in the reported difficult to insert.Manipulation of the device resulted in the noted stretched coils and ultimately resulted in the reported/noted tip separation.There is no indication of a product quality issue with respect to manufacture, design or labeling of the device.
