1. A device having a clamp for securing a lead implanted through a burr hole into a brain of a patient, the device comprising:
(A) a base configured for being mounted at the burr hole, the base comprising a central opening having an inside surface;
(B) an interposer comprising a lower portion having an outer wall, the outer wall cooperating with the inside surface to locate the interposer in the central opening of the base; the interposer further comprising at least one clamping wall, the clamping wall having a clamping surface on one side and an actuation surface on the other side; the interposer further comprising at least one aperture adjoining the clamping wall, the aperture providing an access to the actuation surface of the clamping wall;
(C) a plunger comprising a top portion and at least one actuating tab extending from the top portion, the actuating tab configured to be received in the aperture of the interposer; the actuating tab having an actuating surface cooperating with the corresponding actuation surface of the clamping wall;
whereby when the actuating tab is pressed into the interposer aperture, the clamping wall is resiliently displaced by the actuating tab in the direction normal to the clamping surface, thus activating the clamp.
