Current clinical trial BCIs use surgically placed arrays connected through a percutaneous port anchored to the skull.

“So the work that we've done in our clinical trial is using an array that's surgically placed but connected through uh a port. We call it a perccutaneous port because it's actually physically attached uh and anchored to the skull. It's an array on the brain. It comes out the dura and is anchored in the skull. Um and then where does the port exit the body? uh right on the top of the scalp.”
