Editor’s take
In favor
- Minimally invasive — no craniectomy, ~2-hour catheter procedure
- Implanted by interventional neuroradiologists already trained in stent procedures
- Strong safety record (SWITCH and COMMAND primary endpoints met)
- First permanently-implanted BCI under a US FDA IDE
Against
- Only ~16 channels — orders of magnitude fewer than Neuralink/Paradromics/Precision
- Vascular ECoG signal is lower-resolution than penetrating intracortical recording
- Limited to motor-cortex regions accessible via the sagittal sinus
