USPTO Abstract
ABSTRACT OF THE DISCLOSURE A multiple site drug iontophoresis electronic device configured for controlling infusion of ionic drugs into a patient through a plurality of electrode pairs. The device includes a plurality of electrode driver channels wherein each driver channel includes an electrode output configured for electrical connection to at least one of the plurality of electrode pairs through lead wires. Each driver channel is electrically isolated from the other driver channels and includes an independent current sink which controls current intensity through the electrode output. A common controller operates the driver channels as a function of treatment parameters supplied by the patient.
