Abstract:
1. A patch assembly for iontophoretic transdermal delivery of a therapeutic agent to a patient, the assembly comprising: a conformable patch having two electrodes, the patch having a tissue contacting side including an adhesive and a non tissue contacting side, at least one of the electrodes including a medium to house the therapeutic agent and a porous layer to allow for the iontophoretic transdermal delivery of the therapeutic agent to the patient through the tissue contacting side; a housing having a top surface and a bottom surface, the bottom surface configured to engage the non tissue contacting side of the conformable patch; a current source positioned in or on the housing, the current source configured to deliver direct current; a power inverter coupled to the current source and positioned in or on the housing, the power inverter configured to convert direct current from the current source to alternating current; and a controller positioned in or on the housing and configured to receive the alternating current and control the iontophoretic delivery of the therapeutic agent; wherein the housing has sufficient flexibility such that when the housing is engaged with the conformable patch to form the patch assembly, adhering the conformable patch to a target site on the patient's skin, the patch assembly has sufficient flexibility to deform with movement of the patient's skin so as to remain sufficiently adhered to the patient's skin over an extended period of time to transdermally deliver the agent.
