Abstract
There is disclosed a medical apparatus for positioning and anchoring a lead to a cranium burr hole. The apparatus comprises generally a sleeve and a plurality of springs positioned within the sleeve. The apparatus may be inserted within a conventional burr hole ring or serve as a stand-alone anchoring device that fits within a burr hole. Once a lead is inserted into the sleeve between the plurality of springs, the springs exert a radial force on the lead body, thereby holding the lead in the desired position. The apparatus may also include a circular disc, defining a slot, mountable within the burr hole ring. The circular disc permits the selective positioning of the lead within the burr hole.
