Abstract: The present disclosure relates to an iontophoretic device having a delivery portion and a control portion that are located on a common base layer but separated from one another so as to provide increased flexibility and interface with a wearer.

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.

Abstract: The present application discloses an iontophoretic device with a contact electrode for detecting placement of the device and/or characteristics of the wearer's tissue.
