22. Select the desired amplifier (sensing) channels on the MONTAGE tab (under CONFIGURE
SETTINGS) of the programmer. Program the information into the neurostimulator.
23. View real-time ECoG signals on the R
EAL-TIME ECOGS tab (under REVIEW DATA tab) and
measure lead impedance(s) (under M
EASUREMENTS tab) to ensure proper connection
between the neurostimulator and the leads. If impedance measurements are abnormal or
real-time ECoG signals are not adequate, remove the connector cover and flush the
connector area. Fully reinsert the leads into the connector cover and repeat the impedance
measurements. Refer to the Troubleshooting Section if impedance measurements remain
abnormal.
24. Close the incision.
25. After the incision closure, interrogate the neurostimulator again using the programmer.
Confirm that the impedance measurements and real-time ECoG signals are normal.
Note: It is common for the neurostimulator to reset if electrocautery is used near the
neurostimulator or leads. To recover from a neurostimulator reset, perform the
following:
1. Document all error messages.
2. Proceed with the interrogation.
3. Go to the P
ROGRAM SETTINGS tab and select program.
4. Synchronize the programmer with PDMS (post-operatively).
5. If problems persist, refer to the Troubleshooting section of this manual.
