When the PNE lead is placed through the Foramen needle, the
CP provides test stimulation to help determine if the lead is near
the sacral nerve. This screen shows a visual representation of
the PNE lead ( 1 ) and allows test stimulation of the PNE lead. To
stimulate using the PNE lead:
Connect the foramen needle test stimulation cable to the CP
•
( 2 ) and to the PNE lead. Also connect the stimulation ground
cable to the CP ( 3 ) and to the patient (see the PNE Lead
Implant manual for more details on connecting to the PNE
lead and the patient).
Note: The test stimulation cable is sterile and can be used in the sterile field.
Note: The stimulation ground cable is not sterile. Do not place the ground
electrode in the sterile field.
To deliver stimulation, set the desired stimulation amplitude
•
on the Stimulation Bar ( 6 ) (see Controlling Stimulation
Amplitude for more information). Next press the stimulation
button ( 7 ) to turn on stimulation. The stimulation button will
light up when stimulation is on.
Note: To check the connection between the CP and the PNE lead, press the
"Impedance" button ( 4 ). A qualitative indication of the impedance ("Good",
"OK", or "Bad") will appear for 4 to 6 seconds next to the PNE Lead graphic ( 5 ).
See the section Understanding Impedance Values for more information about
the qualitative impedance indicators.
Only stimulation amplitude is adjustable during PNE lead
stimulation. The stimulation frequency is 14 Hz, and the pulse
width is 210μs. The stimulation frequency can be changed to
5 Hz by exiting Lead Placement and going into CP Settings.
