Abstract
A transdermal drug applicator comprising at least two flexible drug reservoir units each having ends and being of a predetermined depth, and at least one medicament in at least one of the at least two reservoir units. Peripheral means are disposed entirely about the ends of the reservoir units for separating and insulating the reservoir units from each other along their predetermined depth to thereby preclude shorting out between the at least two reservoir units. Circuit means including battery means for electrically connecting the battery means to the at least two reservoir units, and means for covering the applicator including the at least two reservoir units leaving sides of the at least two reservoir units exposed for contacting the skin. The means for covering being flexible and having lip means including an underside for making contact with the skin when mounted on the skin with the at least two reservoir units substantially fully enclosed, so that when the applicator is mounted and retained on the skin, it deforms and conforms to the body in a complete electrical circuit through the skin is formed via the circuit means, and whereby the at least one medicament in at least one of the at least two drug reservoir units migrates out of the reservoir units through the skin into the blood stream of the patient by means of a mass transfer activity attributed to at least one mass transfer phenomenon selected from the group consisting of electrophoresis and electroosmosis.
