We are developing an intravascular neural interface (Stentrode) that can be implanted into the brain via blood vessel able to record brain signals and stimulate the brain. The Stentrode (stent-electrode array) incorporates electrodes with a self-expanding stent and can be deployed into the brain via blood vessels. This technology mitigates the risks associated with open brain surgery. Since stent-mounted electrodes are inside blood vessels and not in direct contact with cortical neurons, the adverse inflammatory reactions that cause signal degradation and rejection of penetrating electrodes can be avoided by this approach. We have shown that we can record and stimulate using the Stentrode.
We are now using this to develop better closed loop neuromodulation and brain machine interfaces to restore lost function for people with paralysis as well as diagnose and treat Epilepsy and Parkinson’s disease.
