Abstract:
1. A method for securing an electrical stimulation lead in position in a person's brain, comprising: inserting an apparatus into a burr hole formed in the person's skull, a body of the apparatus configured to seat within the burr hole, a central elastic membrane of the apparatus extending across a central aperture of the apparatus body, the elastic membrane comprising a plurality of pre-formed openings provided for purposes of securing the lead in position within the brain, each pre-formed opening penetrating through an entire thickness of the elastic membrane, each pre-formed opening being selectable for insertion of the lead into the brain, each pre-formed opening being adapted to elastically expand to receive the lead as the lead is inserted through the pre-formed opening and positioned in the brain and being adapted to elastically contract on the lead to secure the lead in position within the brain after implantation; and inserting the lead through a selected pre-formed opening and positioning the lead within the brain, the selected pre-formed opening elastically expanding as the lead is inserted through the selected pre-formed opening and positioned in the brain, the selected pre-formed opening elastically contracting on the lead to secure the lead in position within the brain after implantation.
