Method and device for the iontophoretic delivery of a drug

A method for iontophoretically applying a stored medicament to a patient, comprising:

• removing a tray assembly from storage, the tray assembly comprising a substantially rigid shell, configured to hold a fluid reservoir and an electrode assembly in relative positions, and a removable cover;
• applying force to a portion of the shell, associated with the fluid reservoir;
• compressing at least a portion of the shell into a top surface of the fluid reservoir;
• fracturing at least a portion of a first region of at least one seal of the fluid reservoir, while substantially maintaining the integrity of a second region of the at least one seal;
• releasing a fluid from a cavity within the fluid reservoir;
• directing the flow of a released fluid out of the cavity, and onto a medicament carrying surface of the electrode assembly;
• separating the electrode assembly from the fluid reservoir by removing the electrode assembly from the tray assembly and retaining the fluid reservoir in the tray assembly;
• applying the electrode assembly to a surface of a patient, wherein the step of applying further comprises:
• placing an active electrode, in electrical communication with the medicament carrying surface, wherein the active electrode is spaced apart from at least two passive electrodes, and wherein the active electrode is configured to create an electric field simultaneously between the active electrode and the at least two passive electrodes, and
• placing the at least two passive electrodes such that the passive electrodes are spaced apart from one another, wherein the active electrode and the at least two passive electrodes are coupled to an attachment surface;
• and
• iontophoretically administering the fluid to a patient using the electrode assembly.
