Abstract
Methods and apparatus for anchoring an elongate medical device within a body portal, for example, a stimulation lead in a cranial burr hole, employ a securing element attached to a plate member, which may be held over a body portal by a base ring. The securing element includes a spring member and an engagement surface; a retaining member holds the engagement surface, spaced apart from a side of a slot of the plate member, in an open position, against a bias of the spring member. In the open position, the device may be received between the engagement surface and the side of the slot, through an opening of the slot. Disengaging the retaining member releases a moveable portion of the spring member to move the engagement surface toward the side of the slot and into a closed position, at which the inserted device is anchored. The anchored device may be routed through one of a plurality of base ring channels.
