A therapeutic treatment apparatus (10) for use in the middle and inner ear. The apparatus (10) includes a tubular stem portion (14) attached to a medicine-retaining reservoir (30) with an internal cavity (38). The reservoir (30) includes multiple pores (46) therethrough or an opening (50) having a semipermeable membrane (54) therein which enables medicine delivery from the reservoir (30). Such delivery occurs when the reservoir (30) comes in contact with selected middle-inner ear interface tissues. A conductive member (70) for receiving electrical potentials from ear tissues is affixed to the apparatus (10). Alternatively, the apparatus (200) may include tubular first and second stem portions (204, 236) secured on opposite sides of a reservoir (220) along with a conductive member (270) attached thereto of the type indicated above.

L'invention concerne un appareil de traitement thérapeutique (10) s'utilisant dans l'oreille moyenne et dans l'oreille interne. L'appareil (10) comprend une partie en forme de tige tubulaire (14) fixée à un réservoir (30) contenant un médicament, avec une cavité interne (38). Le réservoir (30) possède des pores multiples (46) ou une ouverture (50) ayant une membrane semiperméable (54) à l'intérieur qui permet d'acheminer le médicament du réservoir (30). Cet acheminement se produit lorsque le réservoir (30) vient au contact des tissus interfaciaux entre l'oreille moyenne et l'oreille interne. Un élément conducteur (70) recevant des potentiels électriques provenant des tissus de l'oreille est fixé à l'appareil (10). Dans une variante, l'appareil (200) peut comprendre des première et seconde parties tiges tubulaires (204, 236) fixées aux côtés opposés d'un réservoir (220) ainsi qu'un élément conducteur (270) du type indiqué ci-dessus et fixé au réservoir.
