Abstract

A surgically implanted lead stabilizer used to stabilize leads is described herein. A lead stabilizer may include a plate that is permanently or semi-permanently surgically installed on a patient's skull under their skin via screws. The plate may hold one or more lead in place. In further embodiments, the plate has two hinged halves that may be affixed fully closed or may include a slotted arm allowing the two hinged halves to be affixed partially open. The plate may include apertures through which electrical leads may pass. Example leads may be guided through one or more surface channels on the top surface of the plate causing the leads to lay flat along the patient's skull. In an example use, a burr hole may be formed in a patient's skull with one or more leads threaded therethrough; a surgeon may open a hinged half of a plate and clamp one or more leads within one or more of the lead holes of the plate, close the hinged halves partially or entirely, affix the plate to the skull, and snap the leads into the surface channels.
