Claim 0:
1. A system for securing an electrical stimulation lead relative to a burr hole, the system comprising:
a substantially ring shaped base having an opening surface defining a central opening extending therethrough and configured to be placed relative to the burr hole and an upper portion extending from the opening surface having a thickness that defines a channel formed in the upper portion extending from the opening surface toward an exterior of the upper portion, the upper portion having an outer radially curved surface that protrudes above an outer cranial surface above the burr hole where the channel is formed into the outer radially curved surface;
a stabilizer separable from the base and shaped and sized to be inserted within the central opening of the base, wherein the stabilizer has a pair of opposed sidewalls defining a slot extending substantially continuous from and through an outer perimeter of the stabilizer and radially inward from the outer perimeter of the stabilizer, wherein the opposed sidewalls are resiliently biased to a closed position configured to engage the electrical stimulation lead, the opposed sidewalls facing each other in the closed position, each opposed sidewall including a plurality of open-ended notches formed therein starting from the outer perimeter and radially inward, the stabilizer having a pair of ears extending outward from the stabilizer and configured to engage a recess in the base to assist in positioning and holding the stabilizer in place relative to the central opening of the base; and
a cap separate from and configured to be removably coupled to the base to cover the central opening and the burr hole, wherein the cap includes a substantially circular shape having an outer perimeter and at least one tab extending from the outer perimeter of the cap, the tab formed as an elongated protrusion configured to interlock with an opening in the base to secure the cap to the base.
