IONTOPHORESIS APPARATUS AND METHOD TO DELIVER ACTIVE AGENTS TO BIOLOGICAL INTERFACES
First Claim
1. An iontophoresis device, comprising:
- an active electrode element operable to provide an electrical potential;
an outermost ion selective membrane having an outer surface; and
a first amount of active agent carried by at least a portion of the outer surface of the outermost ion selective membrane prior to use in the absence of an electromotive force or current.

Abstract
An iontophoresis device includes active and counter electrode assemblies. The active electrode assembly includes an active electrode element, an outermost ion selective membrane caching an active agent and a further active agent carried by an outer surface of the outermost ion selective membrane. The active electrode assembly may also include an inner active agent reservoir storing additional active agent, an electrolyte reservoir storing electrolyte, an inner ion selective membrane positioned between the electrolyte reservoir and the active agents. The active electrode may also include an inner withdrawable sealing liner between the electrolyte reservoir and the active agents. An outer release liner may protectively cover or overlay the further active agent and/or outer surface prior to use.
