Abstract
In one aspect, an apparatus is provided for securing an electrical stimulation lead in position in a person's brain. The apparatus includes a body configured to seat within a burr hole formed in the person's skull. The apparatus also includes a central elastic membrane coupled to the body and extending across a central aperture of the body. The elastic membrane includes a number of pre-formed openings provided for purposes of securing the lead in position within the brain after implantation. Each pre-formed opening may penetrate through an entire thickness of the elastic membrane. Each pre-formed opening may be selected for insertion of the lead into the brain. Each pre-formed opening is adapted to elastically expand as the lead is inserted through the pre-formed opening and positioned in the brain and is adapted to elastically contract on the lead to secure the lead in position within the brain after implantation.
