A patient underwent a full revision surgery for patient comfort due to a chronic neck pain.The neurologist was unsure if the pain was related to the device or not.The explanted devices were shipped back for analysis.Analysis was completed for the generator, indicating no apparent device malfunctions.The lead assembly was returned in four portions; the portion of the lead assembly including the electrodes and tie downs was not returned.Setscrew marks were observed on both connector pins, indicating good electrical connection existed at one point.Abraded openings were found on both the outer and inner silicone tubing in one of the return portions of the lead.The condition of the returned lead portions is consistent with conditions that typically exist following an explant procedure.Continuity checks of the returned lead portions were performed, during the visual analysis, and no discontinuities were identified.Other than the abraded tubing openings, no additional obvious anomalies were noted.It was concluded that the abraded openings were likely due to normal wear.No additional relevant information has been received to date.
