Abstract: An electrotransport device for delivering one or more therapeutic agents through the skin includes electrodes for contacting the skin, at least one electrode containing the agent, a power source for generating electrical current (IL) for delivering the agent, a current generating and controlling means and a disabling means for permanently and irreversibly disabling the current. The disabling means may include a timer means, a counter means, or a body parameter sensor and limit comparator to effect permanent disabling. The disabling means may be a permanent transition to a disabled logic state, a permanent discharge of a power supply source, or a permanent diversion of electrotransport current from the electrodes, or a combination of the above.

Abstract: An electrotransport system (20) for delivery of a drug through the skin (63) of a patient includes a tactile signal generator (36) for generating and transmitting a tactile signal to the skin of a patient upon the occurrence of an event associated with the operation of the system. The tactile signal may be an electric AC signaling current (Sr, Sp) applied through the skin, ie, an electric current different from the therapeutic electrotransport drive current. The electric signaling current is preferably a pulsed current of sufficient frequency and amplitude to allow the patient to feel it. The tactile signal may alternatively be generated by an electromechanical device in contact with the skin such as a piezoelectric vibrating element or magnetodynamic element such as a solenoid driven pin. The waveform of the tactile signaling current preferably has a zero average current component such that no net therapeutic drug is delivered by the tactile signal current.

Abstract: An electrotransport delivery device (410) includes control circuitry for discontinuously delivering a beneficial agent (eg, a drug) through a body surface (eg, skin 400). For example, the device may be the type which is manually activated by the patient or other medical personnel to activate electrotransport drug delivery. Once electrotransport delivery has been activated, a timer (221) counts a transition interval, typically about one minute, during which the device is allowed to operate and the impedance of the body surface (400) is allowed to stabilize. Thereafter, the electrotransport current and voltage are then monitored and compared to predetermined limits. Allowing for the transition interval permits tighter tolerances in monitoring the applied current.

Abstract: A two-part electrotransport drug delivery device (20) is comprised of a controller (22) which has a plurality of different electronic outputs. The controller (22) is adapted to be mechanically and electrically coupled to a plurality of different drug-containing units (24). Each drug unit (24) includes a means (40, 42, Rx, Cx) for signaling the controller (22). The signal is read by the controller (22) and a predetermined electronic output is thereby selected and applied through the drug unit (24) in order to deliver the drug contained therein by electrotransport. The signal sent by the drug unit (24) to the controller (22) may be an optical signal (e.g., reflected light), a signal sent by an electro-mechanical connector, an electrical signal (e.g., resistance or capacitance), a magnetic signal or a metal detector sensing signal.
