The patient was referred for a prophylactic generator replacement when it reported that low impedance had been observed for quite some time on the generator, the exact date of first observance was not known.X-rays had been performed and the results were reviewed by the physician.Since no lead discontinuity was observed by the physician he decided to leave the lead implanted and only replace the generator.After the new generator was implanted the low impedance continued to be observed.Further follow-up with the physician found the patient felt stimulation at higher settings and the patient's seizure condition were under good control.Additionally, the physician noted that the x-rays did not show any signs of a short circuit condition in the lead.Therefore the physician felt that it was reasonable to leave the system implanted and to only replace the generator when the battery expired.The x-rays have not been reviewed by the manufacturer to date.No additional relevant information has been received to date.
