Electrode-lead coupling skull mounted port assembly

An electrode securing and electrical coupling assembly for securing a deep brain electrode lead to a skull of a patient and coupling said lead to a remote signal generator via a coupling lead;

• comprising:
• a cap element having an axial opening formed therein;
• a cylindrical port element for seating in a hole formed in said skull of said patient, said port element including and upper end and a lower end, said port element further including
• a central opening providing communication between an interior of said skull and an exterior of said skull, said opening being wider than the opening in said cap element,
• an annular lip formed at the upper end, said annular lip including a circumferential groove for receiving therein an end of a deep brain stimulation electrode having at least one electrical terminal, said circumferential groove including at least one electrical terminal pad corresponding to at least one electrical terminal of said electrode,
• an axial recess formed in a sidewall of said opening for securing said electrode therein,
• at least one spline, said at least one spline having at least one individual contact pad, each contact pad being individually electrically connected via conduits in the sidewall of said port to said electrical terminal pads in said circumferential groove, and
• means on said lip for coupling to said cap element;
• and
• a docking element having
• at least one axial recess formed in the top thereof for receiving therein an end of said coupling lead, said recess including at least one electrical contact surface for engaging terminals formed on said tip of said coupling lead,
• at least one spline corresponding to and when fully assembled in electrical contact with the at least one spline of said port element, said at least one electrical contact surface of said recess in said docking element being in individually electrical communication with the at least spline said docking element, such that the coupling lead is in electrical communication with said deep brain stimulation electrode,
• means for securing said coupling lead in said recess in said docking element.
