1. A burr hole plug, comprising:
a base member that is substantially cylindrical and is shaped and dimensioned for positioning within an aperture defined by a burr hole, the base member includes an annular frame member defining an outer perimeter of the base member, the annular frame member further includes at least one cutout section such that open space defined by the radially oriented passageways extends through the annular frame member to allow for the passage of a stimulation lead through the annular frame member and out of the base member, and the base member includes at least one passageway for passage of stimulation leads through the base member, the at least one passageway is defined by a plurality of inwardly directed flange members extending inwardly from the annular frame member toward a center of the annular frame member, wherein each of the plurality of inwardly directed flange members includes an upper surface, a lower surface, edges, and an apex, wherein adjacent edges of the plurality of inwardly directed flange members define radially oriented passageways that extend from the annular frame member toward the center of the base member where they meet to define a central passageway; and
a cover member shaped and dimensioned for placement over the base member to close the burr hole and retain a stimulation lead passing through the burr hole in place, wherein the cover member is disk shaped and includes an upper surface, a lower surface, and a perimeter sidewall extending between the upper surface and the lower surface along an edge of the cover member, wherein the lower surface of the cover member is formed with a plurality of radially extending slots that are oriented as spokes that extend from the perimeter sidewall and that terminate at a central cavity located at the center of the cover member.
