Claim 0:
1. A method for endovascularly accessing a subarachnoid space (SAS) in a patient, the method comprising:
deploying an anchor in the patient at a location distal to a curved wall portion of a venous sinus adjacent a cerebrospinal fluid-filled SAS, wherein an elongate guide member extends proximally from the deployed anchor, through the venous sinus, and into a jugular vein (JV), respectively, of the patient;
advancing an SAS access catheter distally along, on, and/or within the guide member through the JV and toward the curved wall portion of the venous sinus;
retracting a guard body disposed over a penetrating element on a distal portion of the SAS access catheter to at least partially expose the penetrating element in the venous sinus; and
further advancing the SAS access catheter toward and through a target penetration site in the curved wall portion of the venous sinus to create an anastomosis between the venous sinus and the SAS.
