Abstract
Lead fixation devices for mounting at a cranial burr hole and securing a medical lead implanted into a brain through the burr hole. One embodiment comprises a clamp having centrally disposed clamping walls activated by a plunger having actuating tabs. The clamping walls may be an integral part of a device base, or a separate part seated in a central opening of the base. The clamp is activated by pressing the actuating tabs of the plunger into apertures adjoining the clamping walls, which displaces the clamping walls to clamp the lead. Another embodiment comprises a base having a plurality of radial and peripheral lead retention grooves configured to securely retain a substantial segment of the lead at the exit from the burr hole. Still another embodiment comprises both a clamp and peripheral retention grooves to provide a dual fixation and strain relief of the lead within the lead fixation device.
