ABSTRACT:
A method and apparatus for temporary, external, cerebral ventricular drainage in the treatment of hydrocephalus and intracranial hypertension are disclosed in which a flexible catheter having a repositionable guard surrounding its outer circumference with frictional gripping contact is inserted into the cerebral ventricle through a hole drilled in the skull. The guard is then advanced along the outside circumference of the catheter into a position, preferably the junction of the catheter and the skull hole, where the guard fixes the catheter in place and occludes the tract around the catheter by acting as a mechanical blockade and by encouraging a tissue fibrotic seal around the catheter. When the catheter is removed, the guard may be left in place inside the skull hole to eliminate any skull defect and to prevent the leakage of cerebrospinal fluid.
