Abstract
A device for transferring a medicament into the eyeball by iontophoresis. A reservoir holding the active product is applied to a patient's eye. The reservoir has at least one active surface electrode facing the eye tissue lying at the periphery of the cornea. The reservoir also has a return electrode and a current generator. The return electrode is in contact with the patient's partly closed eyelids.
Claims30
A device for transferring at least one active product into an eyeball by iontophoresis, comprising a reservoir configured to receive an active product and having an internal wall, an external wall, and an end wall bridging the internal wall and the external wall, the internal wall and the external wall being annular and having a free end configured to be applied to an eyeball, said device further comprising at least one active electrode arranged in the reservoir, a passive electrode and a current generator, wherein the at least one active electrode is a surface electrode arranged on an interior surface of the end wall and wherein the internal wall has an outer diameter that is configured to be at least equal to a predetermined diameter, whereby the predetermined diameter represents a diameter of a human cornea.
A device for transferring at least one active product into an eyeball by iontophoresis, comprising an annular reservoir configured to receive an active product, the reservoir having an eyeball receiving portion and a plurality of compartments in the form of annular sectors, a plurality of active electrodes arranged in the reservoir in the form of annular sectors, a passive electrode and a current generator, wherein one of the plurality of active electrodes is a surface electrode arranged opposite the eyeball receiving portion.
A device for transferring at least one active product into an eyeball by iontophoresis, comprising an annular reservoir configured to receive an active product, the reservoir having an eyeball receiving portion, at least one active electrode arranged in the reservoir, a passive electrode and a current generator, wherein one of the at least one active electrode is a surface electrode arranged opposite the eyeball receiving portion, and wherein the reservoir has an internal wall, an external wall, and radial spacing fins between the internal wall and the external wall.
A device for transferring at least one active product into an eyeball by iontophoresis, comprising an annular reservoir configured to receive an active product, the reservoir having an eyeball receiving portion, at least one active electrode arranged in the reservoir, a passive electrode and a current generator, wherein one of the at least one active electrode is a surface electrode arranged opposite the eyeball receiving portion, and wherein the reservoir has an internal wall, an external wall, and spacing fins between the internal wall and the external wall, the spacing fins being curved and convex in a direction of an inlet for the active product.
A device for transferring at least one active product into an eyeball by iontophoresis, comprising a reservoir configured to receive an active product, the reservoir having an eyeball receiving portion, at least one active electrode arranged in the reservoir, a passive electrode and a current generator, wherein one of the at least one active electrode is a surface electrode arranged opposite the eyeball receiving portion, and wherein the reservoir defines a central space, the central space being closed off on an external side thereof by a transparent diaphragm configured to depressurize the central space.
