Abstract
A cranial implant may include an interior guide portion, an exterior guide portion, and one or more flanges. In one example, the interior guide portion may be disposed in a burr hole of a cranium and include a distal end, a proximal end, an inner surface, and an outer surface. The distal end may be inserted further into the burr hole than the proximal end. The inner surface may at least partially define a channel that accepts an elongated member, and the outer surface may extend around the full circumference of the burr hole. The exterior guide portion may be coupled to the interior guide portion and may contact an external surface of the cranium. The interior guide portion may define one or more surface features configured to secure the interior guide portion to the burr hole or secure an elongated member within the channel of the cranial implant.
