Abstract

A lead fixation device for attaching a deep brain stimulation lead within in a burr hole in a human skull. The lead fixation device may comprise a mounting plate and an insertion collar extending from a lower surface of the mounting plate and configured to be received in within the burr hole in the human skull. The mounting plate may comprise a mounting flange, a first arm and a second arm. The mounting flange and the first arm may comprise a static mounting hole while the second arm may comprise an adjustable mounting hole. The second arm may be movable to an operating position when the second arm is compressed toward the first arm, the inner walls of the first and second arms are substantially parallel, and the mounting screw is tightened within the adjustable mounting hole when the second arm is in the operating position.
