Patent ID: 7604644

Claim:
An apparatus for anchoring a therapy delivery device relative to a burr hole, the apparatus comprising: a base operable to seat in or near the burr hole, the base comprising a peripheral portion at least partially surrounding a central opening, the peripheral portion defining a flange portion having an outer diameter larger than the burr hole such that the flange portion is operable to rest upon a cranial surface surrounding the burr hole; and a disk-shaped stabilizer positionable within the central opening, the stabilizer comprising a peripheral edge and opposing first and second inner surfaces that define a slot extending through the peripheral edge of the stabilizer, the first inner surface comprising a movable arm having a cantilevered end, the movable arm lockable in a first position corresponding to the first inner surface being substantially parallel to the second inner surface, wherein, when the movable arm is locked in the first position, the first and second inner surfaces are separated by a distance that is about 2% to about 50% less than an undeflected external dimension of a therapy delivery device positioned between the first and second inner surfaces such that the first and second inner surfaces engage the therapy delivery device with interference at substantially any location along a length of the slot, and wherein the movable arm comprises a ball portion operable to interlock with a socket portion of the stabilizer when the movable arm is in the first position.
