Abstract
An iontophoretic apparatus for ocular iontophoresis comprising a housing element formed to cooperate with the eye. In cooperation with the housing element is a flexible current distribution element that is capable of transmitting electrical current. Coupled to the current distribution element is a conformable medicament containment element that is filled with a medicament which is released under the influence of an electrical current, while a barrier element is provided that is configured to reduce current flow outside of the barrier and aid in the preferential delivery of medicament.
Claims19
In iontophoretic apparatus comprising:
- a housing element;
- a current distribution element coupled to said housing element;
- a medicament containment element coupled to said current distribution element;
- and
- a barrier element surrounding said medicament containment element and configured to be placed in contact with a patient's eye tissue, and to reduce current flow outside of said barrier element, wherein the current distribution element, the medicament element and barrier element are sufficiently thin and flexible so as to facilitate operable positioning and retention of a least a portion of the current distribution element and the medicament containment element between the eyelid and eyeball of a patient.
In iontophoretic apparatus comprising:
- a housing element;
- a flexible current distribution element supported by said housing element;
- a confirmable medicament containment element coupled to said current distribution element and said housing element;
- and
- a barrier element surrounding said medicament containment element and configured to reduce current flow outside of said barrier element, wherein the current distribution element, the medicament element and barrier element are sufficiently thin and flexible so as to facilitate operable positioning and retention of a least a portion of the current distribution element and the medicament containment element between the eyelid and eyeball of a patient.
A method of positioning an iontophoretic apparatus comprising the steps of:
- providing an iontophoretic apparatus having
- a housing element;
- a current distribution element coupled to said housing element;
- a medicament containment element coupled to said current distribution element;
- and
- a barrier element associated with the medicament containment element;
- positioning at least a portion of the medicament containment element and the barrier element on a patient's eye tissue;
- and
- positioning at least a portion of the eyelid surrounding a patient's eye over at least a portion of the medicament containment element and the barrier element.
