Abstract
A system for anchoring a brain lead within a cranial burr hole while closing that hole. A socket is provided with an aperture defining a lead passage and is engageable with the cranial burr hole to secure the socket to the cranium with the lead passage aperture in general alignment with the burr hole. A plug is configured to cooperate with the socket lead passage aperture for mutual engagement of a lead within the aperture while closing that aperture. In a preferred embodiment, the socket includes a split grommet portion formed of a flexible material that is biased to maintain the grommet split open. The socket aperture has a neck portion of reduced size with the plug being configured to engage that neck portion and resist removal of the plug from the socket aperture. The socket is also provided with a flange surrounding the grommet portion with holes in the flange being engageable by a tool to facilitate closure of the grommet split for insertion of the socket in a cranial burr hole.
