Methods and apparatus for securing a therapy delivery device within a burr hole
First Claim
1. 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; and
a stabilizer located in or near the central opening, the stabilizer comprising an outer edge and inner sidewalls, the inner sidewalls defining;
a window passing through the stabilizer;
a passageway extending outwardly from the window through the outer edge; and
two or more slots in communication with the window, the two or more slots each operable to frictionally engage the delivery device at most any location along a slot length.

Abstract
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 through 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.

27. A method for securing a therapy delivery device relative to a burr hole, the method comprising:
-
inserting the therapy delivery device through the burr hole;
positioning a base of a burr hole retention apparatus in or near the burr hole such that the therapy delivery device is located within a central opening of the base;
positioning a stabilizer proximate the base, the stabilizer comprising an outer edge and inner sidewalls, the inner sidewalls defining;
a window passing through the stabilizer;
a passageway extending from the window through the outer edge; and
two or more slots in communication with the window;
positioning the therapy delivery device such that it extends through the window of the stabilizer;
securing the stabilizer relative to the central opening of the base; and
moving the therapy delivery device into a first slot of the two or more slots of the stabilizer, wherein the first slot frictionally engages the therapy delivery device at most any location along a slot length. - View Dependent Claims (28, 29, 30, 31, 32)

33. An implantable therapy delivery system, comprising:
-
a therapy delivery device for implantation through a burr hole;
a therapy source operatively coupled to the therapy delivery device;
an apparatus for anchoring the therapy delivery device relative to the burr hole, wherein the apparatus comprises;
a base operable to seat in or near the burr hole, the base comprising a peripheral portion at least partially surrounding a central opening; and
a stabilizer located in or near the central opening, the stabilizer comprising an outer edge and inner sidewalls, the inner sidewalls defining;
a window passing through the stabilizer;
a passageway extending outwardly from the window through the outer edge; and
two or more slots in communication with the window, the two or more slots each operable to frictionally engage the delivery device at most any location along a slot length. - View Dependent Claims (34, 35)
