b. Pass the Torque Wrench through the slit in the Septum located on the top of the Lead
Boot.
c. Tighten the Setscrew until the Torque Wrench clicks, indicating that the Setscrew is fully
secured.
Note: To tighten the Setscrew, use one hand to grasp the base of the Lead Boot and the
other hand to rotate the Torque Wrench clockwise until it clicks, indicating that the
Setscrew is fully secured (Figure 26). To loosen the Setscrew, rotate the Torque
Wrench counterclockwise.
Caution: The Torque Wrench is torque‑limiting to prevent overtightening of the
Setscrew. Use only the Wrench provided, as other tools may overtighten the
Setscrew and damage the DBS Lead.
d. Create a tunnel to transfer the proximal end of the DBS Lead closer to the desired location
for the Lead Extension Connector.
Caution: Placement of the Extension Connector in the neck region can increase the
risk of device failure due to repetitive movement of the neck.
e. Create a pocket under the skin for the excess DBS Lead and Lead Boot.
f. Coil excess DBS Lead material under the scalp, in the pocket, until it is ready to be
connected to the Lead Extension.
Note: The DBS Lead may be connected to the Lead Extension and IPG in a separate
surgery.

subsections (as applicable) up to this point of the manual to implant the second DBS Lead.
16. Use the Tunneling Tool or appropriate means to tunnel the second DBS Lead to the same side
as the first Lead.
