Impedance Issue During Lead Implant

Out of range impedance
during lead implant
procedure
Red impedance icon shows on the
Foramen Needle Placement screen
when impedance is checked for the
foramen needle connection.
•
Check that the ground pad cable is fully inserted into the CP
and the ground pad is firmly attached to the patient.
•
Check that the clip end of the test stimulation cable is
connected to the non-insulated portion of the needle (just
below the hub and above the triple dash mark) and that the
cable is fully inserted into the CP.
•
Press the impedance button to refresh the impedance
value.
•
If the impedance is still bad, replace the ground pad and
stimulation cable and refresh the impedance.
•
If the impedance is still bad, replace the foramen needle
and then the CP.
•
Contact Axonics if the impedance remains bad.
Red impedance icon(s) shows on
the Define Thresholds screen when
impedance is checked for tined lead
connection to the tined lead
stimulation cable.
•
Check that the tined lead test stimulation cable and ground
pad are fully inserted into the CP and that the ground pad is
on the patient and the clip end of the stimulation cable is
connected to the lead.
•
Make sure the introducer sheath is withdrawn past the
most proximal electrode.
•
Reconnect the clip to the tined lead and check the
impedance. If the bad impedance switches to a different
electrode(s), reconnect the clip again.
•
If all the electrodes continue to show bad impedance,
replace the ground pad and stimulation cable and refresh
the impedance.
•
If the impedance is still bad, replace the tined lead and then
the CP.
•
Contact Axonics if the impedance remains bad.
