ABSTRACT:
A therapeutic treatment apparatus for use in the middle and inner ear. The apparatus includes a tubular stem portion attached to a medicine-retaining reservoir with an internal cavity. The reservoir includes multiple pores therethrough or an opening having a semipermeable membrane therein which enables medicine delivery from the reservoir. Such delivery occurs when the reservoir comes in contact with selected middle-inner ear interface tissues. A conductive member for receiving electrical potentials from ear tissues is affixed to the apparatus. Alternatively, the apparatus may include tubular first and second stem portions secured on opposite sides of a reservoir along with a conductive member attached thereto of the type indicated above. This apparatus is surgically inserted so that the first stem portion is placed within the inner ear. At least part of the apparatus (the second stem portion) resides within the external auditory canal. A further alternative embodiment involves an apparatus with a stem portion, a reservoir, and an inflatable insert member therein. The insert member is operatively connected to a temperature-controlled fluid supply designed to deliver fluids (e.g. gases or liquids) to the insert causing expansion thereof. Such expansion can therapeutically modify the pressure characteristics of inner ear fluids and fluid chambers.
