4. Verify impedances are acceptable by using the CP or Remote Control to measure
monopolar impedances.
If using the CP, high impedance contacts will contain a red X. If using the
Remote Control, high impedance contacts are represented by hollow rectangles.
Note: If using the Remote Control, press ▼ to view the impedance values.
5. Evaluate DBS Lead placement.
a. Evaluate whether stimulation is appropriate to reduce symptoms.
b. Adjust the DBS Lead location or stimulation parameters if necessary.
Note: The stylet shall remain in place throughout DBS Lead insertion and
adjustments.
WARNING: High charge density can cause permanent tissue damage. A warning
will pop-up on the Clinician Programmer screen if the stimulation
parameters will cause the charge density to exceed 30 µC/cm
WARNING: Increasing the number of DBS Lead penetrations increases the
probability of hemorrhage. The necessity for an acute DBS Lead
revision should be minimized using techniques of target localization,
such as microelectrode recordings and imaging, to correctly place the
DBS Leads on the first attempt.
6. Turn off the External Trial Stimulator.
WARNING: A sudden increase in stimulation may occur if External Trial
Stimulator is ON while disconnecting the OR Cables.
7. Disconnect the OR Cable and OR Cable Extension from the proximal end of the
DBS Lead.
8. Verify that the DBS Lead has not moved from the desired location.
