(b)(4).Internal file number - (b)(4): during processing of this complaint, attempts were made to obtain complete event, patient and device information.Evaluation summary: the device was returned for analysis.The reported detachment was unable to be confirmed however there was a noted polymer separation.The reported torn polymer was able to be confirmed.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.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that interaction with other devices as the guide wire was being removed resulted in the reported/noted polymer detachment/break and the reported/noted torn polymer.Based on the information reviewed, there is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.

It was reported that the procedure was to treat non-tortuous, non-calcified, de novo lesions on both sides of the common iliac artery (cia).Non-abbott stents were implanted using a ht command 18 guide wire and the stents post-dilated with non-abbott balloons.No resistance was noted during use of the wire and when it was removed, the polymer cover was noted to be split and separated.It is unknown if any portion of the polymer coating remains in the patient.There was no reported adverse patient sequela or a clinically significant delay in the procedure.A new same size ht command 18 guide wire was used to successfully complete the procedure.No additional information was provided.
