Editor’s take
In favor
- Only FDA-approved closed-loop responsive neurostimulator
- Provides longitudinal ambulatory iEEG that no other device can
- Skull-flush form factor avoids chest IPG and tunneled extensions
Against
- Indication limited to 1–2 well-localized seizure foci
- Non-rechargeable; surgical replacement required at end-of-service
- No raw data access for patients or third parties
