Impedance Issue with the Neurostimulator
Issue
Presentation
Resolution
Out of range ("Bad")
impedance during the
Neurostimulator
implant procedure
Red impedance icon(s) shows on the
Patient Device screen when
impedance is checked after the lead
is inserted into the Neurostimulator.
•
Make sure the Neurostimulator is in the subcutaneous
pocket. Press the impedance button to refresh the impedance
values.
•
If 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 cannot 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 counterclockwise) 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.
Out of range ("Bad")
impedance at a
follow-up or
programming visit
Red impedance icon(s) shows
on the Patient Device screen
when the CP is connected to the
Neurostimulator.
•
Press the impedance button to refresh impedance values.
•
If the bad impedance is still present, reprogram the
stimulation using electrodes with in-range impedance values.
•
If no electrodes have in-range impedance values, replace the
CP.
•
If impedance is still bad on all electrodes, device replacement
may be necessary. Contact Axonics.
