CA 2632131

The invention relates to a device for delivering active substances using ocular iontophoresis. The device includes a reservoir having an outer wall and a hollow body at least partly delimited by the outer wall, wherein the hollow body is capable of receiving an electrical conductive medium and active substances contained in the medium and has an outlet defining a surface, so- called "application surface." The application surface is intended to receive a determine part of an eyeball surface or in alternative embodiments an exterior surface of at least one eyelid, the application surface being at least partly limited by an outer line concave towards the optical axis of the eyeball, wherein the outer wall extends from the outer line with a global outwardly with respect to the said optical axis.

La présente invention concerne un dispositif d'administration de substances actives utilisant une iontophorèse oculaire. Le dispositif comprend un réservoir ayant une paroi externe et un corps creux au moins partiellement limité par la paroi externe, sachant que le corps creux peut recevoir un médium conducteur d~électricité et les substances actives contenues dans le médium et qu~il comprend une sortie définissant une surface, intitulée « surface d~application ». Cette surface est destinée à recevoir une partie déterminée de surface d~orbite ou dans d~autres modes de réalisation, la surface extérieure d~au moins une paupière, la surface d~application étant au moins partiellement limitée par une ligne concave externe vers l~axe optique de l~orbite, sachant que la paroi externe s~étend depuis la ligne externe avec un global externe par rapport audit axe optique.
