Information was received from a manufacturer representative (rep) regarding a patient who was implanted with an implantable neurosti mulator (ins) for spinal pain.It was reported that the rep was trying to program the patient and they were seeing high impedance values on the impedance test results.Prior to calling, the first time the caller checked impedances the electrodes 11 12 13 were out of range with the do not use indicator.The caller tried to program using electrode 10 was getting oor when increasing intensity.The rep re-ran impedances and the results showed that 10 12 and 13 were out of range.During the call the caller provided the following values from the impedance test values: ref (b)(4).The rep indicated that they were only able to get therapy coverage on the patient's left side.The issue was not resolved through troubleshooting.Technical services reviewed information about impedances.The rep was going to continue to try programming with the patient.

Additional information was received from the manufacturer representative (rep) reporting that after speaking with tech services they were told that changing impedances for different electrodes on the same lead was consistent with a possible lead fracture.It was reported that the patient wanted to keep their stimulation programming because they were content with the therapy they were getting at the time.The rep reviewed the possibility of a lead fracture with both the patient and the implanting physician.The physician instructed the patient to notify the rep if there were any changes in therapy at which point they would explore a lead revision.The rep indicated that the patient was asked their weight at the time of the event, but the patient did not know their exact weight.It was indicated that the provided information had been confirmed with the physician.No further complications were reported/anticipated.A manufacturer representative (rep) called in later on (b)(6) 2021, reporting that they were following up on a case for which he checked the patient's device today.The caller indicated that they tested impedances and 5 contacts showed the red indicators with va lues >40000ohms.The caller provided the following values: 8 1120ohms 9 1300ohms 14 1450ohms 10 11 12 13 and 15 were all high during the appointment today.The caller indicated that a report was submitted previously by a colleague.That report included that electr odes 11 12 13 were out of range 10 was causing oor to be displayed.The caller asked about potential causes of high impedances.Technical services (tss) reviewed information.The caller will follow-up with the patient and hcp.
