Anchoring apparatus and methods for use

Abstract

An apparatus for securing an implantable lead within tissue of a patient includes a base adapted to be secured to a patient's skull adjacent a craniotomy. The base has an upper surface and a lower surface with a central passage therebetween. The central passage is adapted to receive the implantable lead therethrough. The apparatus also has a cover that is releasably coupled to the base so as to substantially cover the central passage and capture the implantable lead therebetween. A first rotating member is also coupled with the base and the first member is rotationally movable so as to meet and engage the implantable lead at a plurality of positions within the central passage.

What is claimed is: 
     
         1 . A method of securing an implantable lead into tissue of a patient, the method comprising:
 positioning a base having an upper surface, a lower surface and a central passage therebetween adjacent a craniotomy in a skull of the patient;   securing the base to the skull;   inserting an implantable lead through the central passage and into the tissue; and   rotating a first rotating member coupled with the base so as to meet and engage the implantable lead at a plurality of positions within the central passage.
