Insert the percutaneous lead
1.
Feed the percutaneous lead with the stylet, through the needle into the epidural
space (refer to Figure 5.4).
Figure 5.4: Feeding the percutaneous lead and stylet through the needle.
Position the percutaneous lead
1.
Use the Stylet handle to rotate and guide the percutaneous lead with one hand as
you advance it with the other, while viewing it under fluoroscopy.
2.
Continue advancing the percutaneous lead to the required location.
•
The percutaneous lead is pre-loaded with the bent stylet.
•
You can replace the bent stylet with the straight stylet if required.
Confirm optimal placement of the lead
Physicians may have a preference on the method to confirm optimal lead placement in the
operating room. Lead position may be confirmed anatomically by incorporating Evoked
Compound Action Potential (ECAP) measurement or through paresthesia mapping using
intraoperative patient feedback.
For intra-operative testing methods, refer to section 10 ‘Intra-Operative Testing’.
Create an incision at the epidural needle insertion site
Note:
If the percutaneous lead will be externalized for a trial period, go to section 8 ‘Trial
with a Temporary Percutaneous Lead’, otherwise continue.
1.
Create an incision around the needle sufficiently large to accommodate a strain relief
loop and the anchors for each percutaneous lead.
