Abstract
A neural prosthetic drug delivery apparatus for reducing or eliminating the effects of tinnitus. The apparatus includes a catheter which is inserted into the patient's auditory cortex or thalamus. The catheter microinfuses drugs which suppress or eliminate abnormal neural activity into geometrically separate locations of the patient's brain, thereby reducing or eliminating the effects of tinnitus. In one embodiment the apparatus includes a stimulation device for outputting processed electrical signals and an electrode having a plurality of electrical contacts which is arranged in a target zone of the patient's brain. Each of the plurality of electrical contacts independently outputs electrical discharges in accordance with the electrical signals.
