Abstract

Brain-machine interfaces enable control of prostheses for people with spinal cord injury, loss of limb and other movement disorders. Many sophisticated prostheses have been developed that provide many degrees-of-freedom of operation. However, to provide adequate input to these systems has so far required direct implantation of electrodes into the brain via open craniotomy. We have developed a passive stent-electrode recording array, called the “Stentrode”, that provides a minimally invasive approach that avoids brain trauma by placing the electrodes within a blood vessel in the brain. We have so far demonstrated feasibility of chronically recording brain activity from within veins for up to 190 days in pre-clinical trials, and are now gearing up for human trials by early 2018.
