Abstract: The present disclosure relates to an iontophoretic device. In one aspect, the device includes a barrier layer between the drug reservoir and wearer. In another aspect, the device includes a counterelectrode opposite the driving electrode relative to the drug reservoir.

Abstract: The current invention is directed to an iontophoretic drug delivery system which drives charged drug molecules into a tissue, which comprises a body configured to be disposed on the tissue; a procedure window extending through said body, said window being open to provide access to the tissue for performance of a medical procedure on the tissue; a drug reservoir for holding the charged drug molecules; an electrode for driving the charged drug molecules into the tissue; and a controller configured to control the electrode.

Abstract: The iontophoretic drug delivery system includes electrodes controlled by a microprocessor controller to drive charged molecules contained in a drug reservoir through the skin into the issues of a patient. The iontophoretic drug delivery system further includes an antenna connected to the programmable microprocessor. The antenna allows for the programming of the microprocessor and for the exchange of patient, drug, and treatment related information between the microprocessor and an external device. The iontophoretic drug delivery system is also provided with buttons to allow a patient to manually activate the drug delivery system. The iontophoretic drug delivery system is housed within a thin polyester film membrane.
