Provided is a method of delivering a physiologically acceptable liquid into the cerebral spinal pathway at high flow rates: initiating flow into a ventricular catheter, through a cerebral spinal pathway, and out a lumbar outflow catheter with the patient in a supine position and using a first flow rate, wherein a positive first value for an outlet pressure is maintained in plumbing from the lumbar outflow catheter; and increasing flow to a second flow rate greater than the first in conjunction with decreasing the outlet pressure to a second, negative value. |
