Abstract: A tool for implanting spiral nerve cuff electrodes about a nerve which can be maneuvered into difficult-to-access areas within the body of a mammal. The tool consists of a handle/control device which is coupled to an electrode holding valve assembly at the distal end of the tool by a flexible connection, allowing for accurate positioning of the electrode at the implantation site. The tool handle/control device is coupled to the valve assembly such that the control device can be rotated to release the electrode, which is held to the valve assembly by a vacuum, while the handle is held steady to ensure the precise location of the electrode at a site remote from the handle. The vacuum holding the electrode can be removed from portions of the electrode sequentially, allowing the spiral electrode to curl around the nerve.
