(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.The device was not returned for analysis.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 the device was not returned for analysis, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that the guide wire hydrophilic coating was not fully activated and/or a coagulation of blood and/or contrast on the guide wire resulted in the reported physical property issue (lost lubricity); thus resulting in the reported difficulty to position and the reported difficulty to remove.There is no indication of a product quality issue with respect to manufacture, design or labeling.
