TROUBLESHOOTING
Impedance Issue with the Stimulator
Issue
Out of range ("Bad") impedance
at a follow-up or programming
visit
Out of range ("Bad") impedance
during the Neurostimulator
implant procedure
Presentation
Red impedance icon(s) shows on the
Patient Device screen when the CP is
connected to the Stimulator
Red impedance icon(s) shows on the
Patient Device screen when impedance
is checked after the lead is inserted into
the Neurostimulator.
Resolution
Press the impedance button to refresh impedance values.
•
If the bad impedance is still present, check that the
•
Stimulator is connected to the trial cable (Basic Trial Cable
or Percutaneous Extension). If using a ground pad, confirm
the ground pad is connected to the patient and to the trial
cable. Refresh the impedance values.
If the bad impedance is still present, reprogram the
•
stimulation using electrodes with in‐range impedance values.
If impedance is still bad on all electrodes, device
•
replacement may be necessary. Contact Axonics.
Make sure the Neurostimulator is in the subcutaneous
•
pocket. Press the impedance button to refresh the
impedance values.
If the bad impedance is still red for any electrode(s),
•
disengage the setscrew and remove the lead from the
Neurostimulator and wipe it clean. Reinsert the lead into the
Neurostimulator connector block until it cannon be inserted
any further. The white marker on the proximal end of the
lead should be inside the Neurostimulator strain relief.
If the lead cannot go all the way in, back out the set screw
•
(turn counterlcockwise) and reinsert the lead.
Press the impedance button to refresh the impedance
•
values.
If impedance is still red for any electrode(s), replace
•
the CP and check the impedance. Next replace the
Neurostimulator and check the impedance. Next replace
the tined lead.
Contact Axonics if the impedance remains bad.
