A catheter assembly 10 for intracranial treatment of a patient is disclosed. The assembly comprises an outer catheter 30 and an inner catheter 50. The outer catheter includes a proximal opening 31, at least one aperture 32, a lumen 33 connecting the opening and the aperture, and at least one element 40. The inner catheter 50 is adapted to be received within the lumen and includes a passageway 51 and at least one port 52 for transferring fluids between the inner catheter and a tissue region 81 within the patient's brain 80. The assembly facilitates regular accurate placement of the drug delivery catheter at the tissue region without additional extended contact with the brain during insertion.
