First Claim
Patent Images
1. A system for securing an electrical stimulation lead relative to a burr hole, the system comprising:
- a base defining a central opening extending therethrough, wherein the base is configured to be placed relative to the burr hole;
a stabilizer having a pair of opposed sidewalls extending from an outer perimeter of the stabilizer towards a center of the stabilizer to define a slot extending through the outer perimeter of the stabilizer when the stabilizer is secured relative to the base, wherein the opposed sidewalls are biased to a closed position and configured to engage the electrical stimulation lead, the opposed sidewalls facing each other, the stabilizer being positionable within the opening of the base and movable relative thereto; and
a cap configured to be removably coupled to the base to cover the central opening;
wherein the base is substantially ring shaped and defines an outer perimeter and an inner perimeter, wherein the inner perimeter defines the central opening configured to be positioned over the burr hole and the outer perimeter includes an upper surface of a portion operable to seat near the burr hole;
wherein the central opening and the cap are substantially circular in shape;
wherein the base defines at least one channel formed in the upper surface thereof and extending radially between the inner perimeter and the outer perimeter, wherein the at least one channel is sized and shaped to receive a portion of the lead therein;
wherein each of the opposed sidewalls include open-ended notches;
wherein the at least one channel and open ended notches are sized and positioned to secure the lead in a first direction by the open-ended notches and in a second direction by the at least one channel;
wherein an opening between the opposed sidewalls is operable to be aligned with the at least one channel.
