Stentrode


Stentrode
PROBLEM
Traditional intracranial electrode arrays for recording and stimulating brain activity require direct implantation into the brain via open craniotomy, which can lead to brain trauma.
SOLUTION
Stentrode demonstrates the feasibility of chronically recording brain activity from within a vein using a passive stent-electrode recording array.
It has achieved implantation into a superficial cortical vein overlying the motor cortex via catheter angiography and demonstrate neural recordings in sheep for 190 days.
CHALLENGES
More trials on human bodies will be required to determine effectiveness/safety/
IMPACT
The stentrode can record brain signals from within a blood vessel. These thoughts are captured, decoded and passed wirelessly through the skin to enable control of an external device, such as a prosthetic limb. Once perfected, the stentrode could also allow U.S. soldiers to move and react faster on the battlefield and should eventually allow them to control futuristic mind-controlled weapons via BMI chips in their brains. Stentrodes may also have wide ranging applications as a neural interface for treatment of a range of neurological conditions.
