Neuro Omega Autoclavable Drive Headstage
Intended use: An electrical conductor intended to be temporarily placed (< 30 days) beneath the surface of the brain to stimulate the brain or to record the brain's electrical activity (with more precise localization than a scalp electrode). It is typically a fine, flexible plastic device attached to wires that carry currents from deep and superficial brain structures. The wires are connected to recording, monitoring, or stimulation/response devices [e.g., electroencephalograph (EEG), evoked-potential recorder, stimulator]. The implant is particularly helpful in determining site of origin in temporal and frontal lobe epilepsy. This is a single-use device.
Key tips
- ·Electrode impedance drives data quality more than almost any other single factor - check it before assuming an amplifier fault.
- ·Pre-case verification of intraoperative monitoring equipment isn't optional - a mid-case failure has direct surgical-decision consequences.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Electrode impedance high
MediumSymptoms: Noisy / flat channels, impedance alarm.
Root cause: Dry gel, poor contact.
Amplifier channel fault
MediumSymptoms: Dead channel, artifact.
Root cause: Front-end amplifier failure.
Stimulator output fault
MediumSymptoms: No stimulus delivered.
Root cause: Stimulator circuit wear.
Grounding / isolation issue
LowSymptoms: 50/60 Hz interference.
Root cause: Shield/ground break.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Electrode / lead impedance check
- ·Amplifier calibration
- ·Annual electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Electrode impedance high
- Confirm the presentation - typically noisy / flat channels, impedance alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: dry gel, poor contact.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the eEG electrode cap / cup per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
