摘要： An implantable drug delivery accessory is described. A middle ear guide member has a hollow interior enclosed by a non-permeable outer surface. A proximal end of the middle ear guide member is fixed to the tympanic membrane of an implanted patient. A distal end of the middle ear guide member penetrates through a fluid-tight sealed opening into the inner ear. An inner ear holding member has a proximal end 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 holding member contains a replaceable drug delivery member which stores a therapeutic drug. A semi-permeable outer surface of the inner ear holding member is connected to a cochlear implant electrode and adapted to release therapeutic drug from the hollow interior into adjacent tissue. The drug delivery member is removable and replaceable via the ear canal of the implanted patient through the proximal end of the middle ear.
