METHODS AND APPARATUS FOR SECURING A THERAPY DELIVERY DEVICE WITHIN A BURR HOLE

摘要

Apparatus and methods for securing a therapy delivery device relative to a burr hole. In one embodiment, the apparatus includes a base that is securable to bone, without the use of fasteners, either before or after insertion of the therapy delivery device into the burr hole. The apparatus may further include a stabilizer that may be engaged with both the base and the therapy delivery device while the delivery device is held with positioning apparatus. The base and/or stabilizer may frictionally engage the delivery device, e.g., receive it with interference, to secure the device in two or more non-parallel directions. In some embodiments, at least the stabilizer may include a surface coating or treatment operable to enhance frictional engagement with the therapy delivery device.
