Caution: Use gentle traction on percutaneous extension to avoid
dislodging the lead.
Figure 14. Withdraw the external segment of the percutaneous extension.
2. Cut off and discard this section of extension.
3. Locate the percutaneous extension connector at the proximal end of the
lead and make an incision to expose it. Allow room to hold the lead
connection firmly to prevent dislodgement.
4. Cut the distal ligature on the lead end of the connection. Then cut the
connector boot over the setscrews to expose the setscrews (Figure 15).
Figure 15. Cut the ligature and connector boot to expose setscrews.
5. Hold each setscrew connector block firmly between thumb and two
fingers to prevent rotation while loosening setscrews (Figure 16).
Figure 16. Hold setscrew connector block between thumb and two fingers.
6. Using the torque wrench, loosen each of the four setscrews by turning
the wrench counter-clockwise (approximately one turn) (Figure 17).
Note: Ensure the torque wrench is perpendicular to the setscrew
surface while loosening the setscrew.
Caution: Hold the setscrew connector block firmly between
thumb and two fingers to support the lead body and prevent
rotation. Failure to properly prevent rotation may break or damage
the lead, and may require lead replacement.
