摘要:
The invention concerns an electrostimulation and/or iontophoresis device comprising a patch (10) suitable for application to a user's skin (12) and a voltage generator (22) suitable for applying a low intensity current through the user's skin by a system of electrodes located in said patch; This device is characterised in that it comprises a self-regulator (16) that varies the voltage supplied by the voltage generator as a function of the continuous measurement of the resistivity of the user's skin beneath said patch The resistance value of the skin provided by an element for measuring the resistance of the skin (24) yields the resistivity measurement.

Embodiments of the invention provide methods for the transdermal delivery of therapeutic agents for the treatment of addictive cravings e.g., nicotine compounds for the treatment of nicotine cravings from tobacco use. An embodiment of a method for such delivery comprises positioning at least one electrode assembly in electrical communication with a patient's skin. The assembly includes a solution comprising a therapeutic agent which passively diffuses into the skin. A dose of agent is delivered from the assembly into the skin during a first period using a first current having a characteristic e.g., polarity and magnitude, to repel the agent out of the assembly. During a second period, a second current having a characteristic to attract the agent is used to retain the agent in the assembly such that delivery of agent into skin is minimized. A dose of agent may be delivered on demand by an input from the patient.

Electrotransport drug delivery devices, system and methods of using configured to determine if a current is present between the anode and cathode when drug is not intended to be delivered by the device. These devices/systems may include an off-current module to determine that any current (e.g., which may be inferred by measuring potential difference between the anode and cathode of the device) flowing between the anode and cathode is below a threshold value when the device is not supposed to be delivering drug, thereby preventing unintended delivery of drug and/or alerting a user that unintended delivery of drug may occur.

A system for delivering light and/or ultrasound across a skin surface is provided. The system includes a device having a layered structure comprising one or both of a light source and an ultrasonic transducer. The light source comprises a flexible light emitter layer electrically coupled to a first conductive layer and a second conductive layer, wherein at least one of the first and second conductive layers is transparent. The ultrasonic transducer comprises a flexible ultrasound emitter layer electrically coupled to a third conductive layer and a fourth conductive layer. The system also includes one or more sensors in contact with the skin surface and a controller electrically coupled to the device and the sensor. The controller is operable to receive sensor data from the sensor and dynamically control the device in response to the received sensor data.

Embodiment of a method for such delivery comprises positioning at least one electrode assembly in electrical communication with a patient's skin. The assembly includes a solution comprising a therapeutic agent which passively diffuses into skin. A dose of agent is delivered from the assembly into skin during a first period using a first current having a characteristic e.g., polarity and magnitude, to repel agent out of the assembly. During a second period, a second current having a characteristic to attract agent is used to retain agent in the assembly such that delivery of agent into skin is minimized. In particular embodiments, a dose of agent may be delivered on-demand using an input from the patient using an inhalation sensing device which mimics an inhaled form of tobacco.
