Embodiment Construction

[0048] A. Direct injection of therapeutic agents and other types of agents into the inner ear.

[0049] At least some embodiments of the present invention provide methods for treating inner ear disorders by injecting therapeutic agents (and other types) directly into the cochlea using a device. Direct injection into the cochlea overcomes many of the shortcomings of oral and other parenteral delivery methods. For example, drugs that reduce the symptoms of tinnitus and can achieve the same purpose by directly acting on the underlying molecular mechanism of tinnitus include: clonazepam, alprazolam, memantine (see US Patent No. 6,066,652), ring amygdalus Esters, caroverin (see US Patent No. 5,563,140), lidocaine, tocainide, gabapentin. These drugs target various receptors in the auditory system that are responsible for nerve signal transduction. Unfortunately, under the effective dose of tinnitus control, the use of these drugs has side effects, which limits their oral or systemic adm...

Abstract

The present invention discloses an apparatus may include a needle for sustained delivery of drugs and other agents to the inner ear or other tissues of a human or an animal. The needle can include an insertion stop, and can be placed through the round window membrane or through a surgically-prepared hole in a bone. The needle can be in fluid communication with a port and/or with a micro-infusion or osmotic pump. A cochlear implant electrode can be used instead of a needle.
