Human drug delivery device for tinnitus
First Claim
1. A neural therapeutic apparatus for treatment of a patient with tinnitus, comprising:
- a drug reservoir-pump for containing and pumping a drug, wherein said drug is capable of reducing abnormal neural activity associated with tinnitus; and
a drug delivering catheter for arrangement in the patient'"'"'s auditory, cortex or thalamus, said drug delivering catheter operatively connected to said drug reservoir-pump, and said drug delivering catheter having a plurality of ports, each of said plurality of ports capable of outputting said drug to predetermined geometric locations within said one of the patient'"'"'s auditory, cortex and thalamus.

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.

11. A neural therapeutic apparatus for implantation in a target zone of a patient'"'"'s brain, comprising:
-
a reservoir-pump for containing a drug, said drug capable of reducing abnormal neural activity, associated with tinnitus; a catheter for delivering said drug to the target zone of the patient'"'"'s brain, said catheter operably connected to said reservoir-pump, and comprising one or more stimulating and recording electrodes; a stimulation device for outputting electrical signals to said one or more electrodes, said electrodes outputting electrical discharges in accordance with said electrical signals, wherein said outputted electrical discharges block abnormal neural activity; and a recording device operably connected to said one or more electrodes, said recording device capable of recording electrophysiologic data received by said one or more electrodes, from said target zone of the patient'"'"'s brain. - View Dependent Claims (12, 13, 14, 15, 16)
