Troubleshooting
Troubleshooting During a Routine Follow-up
1. Repeat lead impedance measurements to verify abnormal lead impedance.
2. Take an image (X-ray or CT scan) of the implanted lead(s) and connector cover to discern
the integrity of the lead.
•
Lead Damage – If the lead is damaged or fractured, it is recommended to abandon and
replace the lead. Refer to the instructions in the relevant section of the system manual.
•
Poor Connection – If the lead is not completely installed in the connector cover, it is
recommended to surgically revise the connection between the connector cover and
lead. Refer to the instructions in the relevant section of the system manual.
Note: It is normal for lead impedance measurements to fluctuate following the implant procedure
due to the acute injury and healing processes of the brain tissue.
Note: Lead damage may not be immediately apparent from the live ECoGs. Using the N
ECoG capture trigger may be helpful in future troubleshooting techniques.
