Abstract
An implantable drug delivery system includes a middle ear section with a proximal end fixed to a tympanic membrane of a patient, and a distal end that penetrates through a fluid-tight sealed opening into the inner ear. An inner ear section has a proximal end that is connected to the distal end of the middle ear guide member at the sealed opening, and a closed distal end terminating the inner ear holding member some predetermined distance within the cochlea. A hollow interior of the inner ear section is configured for containing a replaceable pharmaceutical agent, and an outer surface is configured to release the pharmaceutical agent from the hollow interior into the inner ear of the patient. The middle ear section and the inner ear section are configured to cooperate for replacing the pharmaceutical agent through the proximal end of the middle ear section to the inner ear section.
