Ocular iontophoresis device
First Claim
1. An ocular iontophoresis device for delivering active substances to an eyeball, the ocular iontophoresis device comprising:
- an active electrode;
a reservoir having an inlet comprising a rigid material for maintaining a shape of the active electrode and an outlet comprising a flexible material suitable for making contact with the eyeball, the inlet and the outlet each having a respective shape, wherein the area of the inlet shape is greater than the area of the outlet; and
wherein the outlet defines an application surface adapted to receive a predetermined part of an eyeball surface, wherein an area of the active electrode (“
Se”
) is greater than an area of the application surface (“
Sa”
) to provide an increased electric field intensity by a value proportionate to the ratio “
Se/Sa”
, the application surface configured in the shape of at least one of an entire ring, a disk, a portion of a ring, an ellipse, or eye-shaped.

Abstract
The invention relates to a device of ocular iontophoresis for delivering active substances, comprising 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”, intended to received a determine part of an eyeball surface, 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.
