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 flexible disc comprising a substantially radial slot adapted to secure the lead in position within the brain after implantation. The slot is adapted to elastically expand as the lead is inserted into the slot and is also adapted to elastically contract on the lead to secure the lead in position within the brain after implantation. The apparatus further includes a ring adapted to seat within a burr hole formed in the person's skull. The ring comprises a channel adapted to receive and secure the flexible disc.
