Abstract:
1. An apparatus, comprising: a unitarily formed base having a first end, a second end, a first surface, and an opposite second surface, each first and second surface being substantially planar and extending between the first end and the second end, the base including an aperture and a connection hole, the aperture and the connection hole extending through the base from the first surface to the second surface and orientated substantially perpendicular to the first surface; a micro-screw having a shaft that extends between a first end and a second end, the first end including a head that is positioned within the base aperture and defines a shoulder, the shaft being threaded and extending from the base first end towards the base second end; at least one retaining bracket mounted to the first surface of the base near the first end and adjacent to the base aperture, the at least one retaining bracket having an inner surface that defines an opening that is sized to receive the micro-screw therethrough such that the micro-screw is positioned between the retaining bracket inner surface and the base first surface, the micro-screw extending through bracket opening such that the shoulder rests against one side of the retaining bracket and an edge of the base aperture, the micro-screw being held along, and rotatable about, an axis parallel to the base, by the retaining bracket; a cannula having an internal bore and being mounted to the first surface; a shuttle having a bore with internal threads and an outer surface that is adjacent to the base first surface and is movable along the base first surface, the internal threads of the bore of the shuttle being in a coupling relationship with the threads of the micro-screw, the micro-screw being rotatable in a first rotary direction causing the shuttle to be advanced along the micro-screw in a first direction, the micro-screw being rotatable in a second rotary direction causing the shuttle to be advanced along the micro-screw in a second direction; an electrode having a first end and a second end and being coupled to the shuttle, the second end of the electrode being threaded through the cannula such that motion of the shuttle along the micro-screw moves the electrode through the cannula; a surface mount connector mounted on the second surface of the base; and, an electrode wire electrically, one end of the electrode wire forming the electrode and another end of the electrode wire being electrically connected to the surface mount connector.
