What they are building
Formed in 2025 by the merger of Neurolutions and the stroke-care company Kandu Health. IpsiHand reads movement intention with a non-invasive EEG headset, from the hemisphere the stroke did not damage, and opens and closes a powered brace worn on the affected hand.

Where they are clinically
Approved / cleared
Authorised by a regulator for a defined use. Always check the scope.
IpsiHand received FDA De Novo marketing authorisation in 2021 for upper-extremity rehabilitation in chronic stroke. It is a non-invasive, prescription device, not an implant. The founding year is that of Neurolutions.
Access today
Available
Authorised and obtainable for a defined group of patients or users.
- Shown in people
- FDA De Novo authorisation in 2021, and a completed at-home study with 109 participants.
- Still an aim
- Reimbursed home therapy at scale, through a Medicare billing code and a telehealth service.
- What stands in the way
- Adoption: whether clinicians prescribe it and payers cover it.

- Apr 2021US FDA — De Novo marketing authorisation. A non-invasive EEG system for upper-extremity rehabilitation in chronic stroke, by prescription. Granted to Neurolutions, now part of Kandu.
Why this company matters
IpsiHand answers a question that implant coverage tends to skip: which BCI did a regulator authorise first? As far as we can establish it was this one, in 2021, non-invasive and for rehabilitation, five years before the first implanted system was registered in China. Washington University, where the technology was developed, calls it the first FDA-authorised BCI for rehabilitation. The device does not restore a lost channel of communication. It uses the BCI as a training signal, on the theory that pairing the intention to move with the movement helps the brain relearn it. The merger with a telehealth company and a Medicare billing code are a test of whether a BCI therapy can be delivered and paid for at home, which every later product will have to pass too.

Families found for Kandu in the EPO’s worldwide database, grouped so that one invention counts once. A filing shows what a company sought to protect. It does not show that the technology was built, is in a product, or works in people, and themes are read from titles, abstracts and classes, not from the claims. How to read this
