Abstract
A method of inserting a drainage catheter into a sagittal sinus having blood flow from an upstream to a downstream direction. A burr hole is created, if necessary, in the cranium of the patient proximate the sagittal sinus. A distal end of a catheter is inserted through the burr hole and the dura into the sagittal sinus. The distal end of the catheter is positioned so that the distal end points generally in the upstream direction with respect to the blood flow. A sagittal sinus catheter is adapted for placement through the dura of a patient proximate a superior sagittal sinus. The catheter is formed of semi-rigid material and has at least a ninety degree bend.
