Abstract	A brain lead anchoring system is described which allows for installation of a brain stimulation lead or a drug delivery catheter without the lead or catheter ever being unsupported during installation so that the lead or catheter does not move during the anchoring procedure. An anchor assembly contains an anchoring mechanism that is biased in the closed or anchoring position and is only open to allow installation of a lead when it is mated to an introducer instrument, which has prongs that open the anchoring mechanism. Once the lead is appropriately positioned within the brain and while the lead is still supported by the installation guiding device, the introducer instrument is withdrawn from the anchoring mechanism, which thus allows the anchoring mechanism to return to its closed position. A locking cap covers the aperture through the anchor assembly into the skull and mechanically ensures that the anchoring mechanism remains in the closed position. The anchor assembly also has channels in its top surface within which the lead may be inserted so that the lead may be lain flat on the surface of the patient's skull.
