2. Insert the PNE lead into the foramen needle. Align the appropriate depth marker on the PNE lead with the top
of the foramen needle (Figure 6). The distal electrode of the PNE lead will extend from the needle tip when the
lead marker is aligned with the needle.
Note: The more distal depth marker should be used for alignment with the shorter foramen needle (9.0 cm or 3.5
in). The more proximal marker should be used with the longer foramen needle (12.5 cm or 5 in).
Caution:
Do not remove the lead stylet until the lead position has been tested and the desired response to test
stimulation is observed. The lead position cannot be adjusted once the stylet is removed.
3. Attach the stim clip to the distal connector of the PNE lead.
4. Test the PNE lead placement by stimulating and observing patient motor and/or sensory responses (Table 2). If
necessary, reposition the lead within the foramen if optimal responses are not obtained.
Caution:
Optimal motor responses should be observed intraoperatively at ≤ 3 mA during test stimulation of the lead. If
the amplitude required to obtain a motor response is larger than 3.0 mA, the lead may not allow for optimal
trial therapy. Consider repositioning the lead to achieve the desired range.
5. When the PNE lead is in the desired location, carefully withdraw the foramen needle over the PNE lead. Then
remove the lead stylet with the PNE lead in place.
Caution:
Be careful to not displace the PNE lead when removing the needle and lead stylet.
Be careful to not stretch the PNE lead while removing the stylet.
6. Reconnect the test stimulation cable to the lead. Test stimulation to confirm the lead placement.
Connecting the Basic Trial Cable
1. Place the ground pad on the lower back. Connect its cable to the ground connector on the Basic trial cable (if
using the ground pad) (Figure 7).
Figure 7 . Insert the ground pad connector into the center, white connector of the Basic Trial Cable.
Figure 6 . Insert the PNE lead until the appropriate depth
marker is aligned with the hub of the foramen needle.
