ABSTRACT:
A system for anchoring a lead within a cranial burr hole. The system provides for a lead to be anchored in either of two sizes of burr holes. In further provides for the lead to remain secured to the stereotactic instrument during the installation of the lead anchoring system. The lead anchoring system consists of three parts: A plug having a central lead passage; a cap configured to fit over the plug while the lead is retained by the stereotactic instrument and thereby seal the burr hole and anchor the lead; and a socket designed to permit the plug to be fitted within a larger sized burr hole. In the preferred embodiment each of the parts, i.e. plug, socket and cap are constructed from silicone. The anchoring system of the present invention may be employed with a stimulation lead, a sensing lead, a combination thereof or any other elongated member requiring passage and fixation through the cranium.
