Abstract

An assembly for securing an electrode lead within a burr hole formed in a patient's skull and couples it to a coupling lead which extends to a remote signal generator. The securing assembly has three separate components. The first is a bone port which seats within a preformed burr hole in the skull. The bone port is a cylindrical shaped short tube with central axial hole having electrical contacts formed on the inner surface. These electrical contacts are connected to corresponding contacts in a circumferential groove formed in the upper surface of the port for receiving the proximal end of the stimulation electrode. The second component is a docking element which seats in the port. The docking element has corresponding electrical contacts on the exterior surface thereof, which connect to terminal pads in an axial bore formed therein. The coupling lead is inserted into the bore and is thereby connected to the stimulation electrode by virtue of the contacts made between the port and the docking element. A cap element seats over the port and docking elements, holding them together and securing the stimulation electrode in the assembly.
