Title
(EN) APPARATUS FOR DELIVERY OF PHARMACEUTICALS TO THE COCHLEA
(FR) APPAREIL DE DISTRIBUTION DE PRODUITS PHARMACEUTIQUES A L'ORGANE COCHLEAIRE
Abstract
(EN)
An implantable tissue-stimulating device, such as a cochlear implant, having a resiliently flexible elongate member (11) having a plurality of electrodes (12) positioned thereon. The elongate member (11) provides a means of delivering at least one bio-active substance to the implantee following implantation of the elongate member (11). The delivery means can comprise a lumen 21 containing the bio-active substance in a liquid form. The bio-active substance can comprise a steroid or can perform a function of reducing the resting neuron potential of neurons within the cochlea.
(FR)
L'invention concerne un dispositif implantable stimulateur de tissu, tel qu'un implant cochléaire, comprenant un élément oblong souple résilient (11) comportant plusieurs électrodes (12). L'élément oblong (11) constitue un moyen de distribution d'au moins une substance bio-active au sujet suite à l'implantation de l'élément oblong (11). Les moyens de distribution peuvent comprendre une lumière (21) contenant la substance bio-active sous une forme liquide. La substance bio-active peut être un stéroïde ou bien peut remplir une fonction ou réduire le potentiel neuronal de repos des neurones de l'organe cochléaire.
