Abstract
A catheter system is provided having an outer catheter and at least one inner catheter chosen from a plurality of different inner catheters for delivery of a treatment agent to a selected tissue region of the brain. The outer catheter has a lumen in communication with an opening and at least one aperture. Each inner catheter is sized to be received within the lumen and has a passageway and at least one port in communication with that passageway. The system preferably has inner catheters having different lengths and/or passageways with different diameters. The outer catheter can include an element that monitors brain activity. The outer catheter can also have an inflatable balloon proximal to an element. A method of delivering a treatment agent, preferably a drug, to a select tissue region of a targeted area of the brain for intracranial treatment of a patient is also disclosed.
