3. Verify that the retention sleeve on the DBS Extension is located directly under the
Setscrew in the Stimulator header.
Note: The retention sleeve is easily distinguishable from the contacts by its length (see
below).
4. Pass the Torque Wrench through the slit in the septum located on the top of the
Stimulator header.
5. Tighten the Setscrew in the Stimulator until the Torque Wrench clicks, indicating the
Setscrew is fully secured.
Note: To tighten the Setscrew, rotate the Torque Wrench clockwise. To loosen the
Setscrew, rotate the Torque Wrench counterclockwise.
CAUTION: The wrench is torque limiting, such that the Setscrew cannot be over
tightened. Use only the wrench provided, as other tools may over‑tighten
the Setscrew and damage the DBS Lead.
