The device was returned for analysis.The reported difficult to insert was able to be confirmed.The reported difficult to remove was able to be confirmed.The reported break was unable to be confirmed however there were noted damage (kinked core, bent shaping ribbon).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 inadvertent mishandling resulted in the noted guide wire damages (kinked core, bent shaping ribbon) thus resulting in the reported/noted difficult to insert and the reported/noted difficult to remove.The reported break was unable to be confirmed.There is no indication of a product quality issue with respect to manufacture, design or labeling.H6: medical device problem code 2920 - removed.
