ABSTRACT:
There is disclosed an adjustable medical apparatus for anchoring a lead to a cranial burr hole. The apparatus comprises generally an anchoring plate mounted to and over a cranial burr hole, an anchoring arm pivotally mounted to the anchoring plate, and a resilient sleeve mounted between the anchoring plate and the anchoring arm. The resilient sleeves defines an aperture for receiving the lead. Once an implanted lead is inserted into the aperture in the resilient sleeve, the anchoring arm is pivoted around the sleeve creating a clamping force on the resilient sleeve. The resilient sleeve in turn creates a clamping force on the lead body, thereby anchoring the lead relative to the anchoring apparatus and thus relative to the cranium. Significantly, the anchoring apparatus accommodates various sized lead bodies which are used within various sized burr holes.
