Abstract
A system and method for providing electrical and/or fluid treatment within a patient's brain, the system and method utilizing a feedthrough assembly made of a compressible material, and a disk-like pinch-on part, or resilient clamping part, which is secured around the feedthrough assembly to provide radially inward compressive force to reliably fix the lead after it has been positioned relative to the patient's skull. The feedthrough assembly is suitably made of a compressible biocompatible material such as silicone rubber, and has a annular receiving groove which is located so that it is accessible above the cranium after the feedthrough assembly is fixed within a burr hole in the patient's head. The pinch-on part, or clamping means is manufactured in a normally closed position, but can be opened, as by use of a forceps-type instrument, for positioning around the assembly annular groove. The anchored lead or catheter member is operatively connected to an implantable pulse generator or fluid pump, or both, to provide a system for treatment within the patient's brain.
