Patch and patch assembly for iontophoretic transdermal delivery of active agents for therapeutic and medicinal purposes

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, each of the electrodes including a porous layer to allow for the iontophoretic transdermal delivery of the therapeutic agent to the patient through the tissue contacting side, each of the electrodes configured to hold a medium to contain the therapeutic agent;
• 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, 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 an alternating current and cause dispersion of the therapeutic agent to alternate between electrodes;
• 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.
