  • Patent number: 6725090
    Abstract: An apparatus for the electrically assisted delivery of therapeutic agent is described. An apparatus of the invention has rigid zones or regions which are physically connected by flexible means such as a web. The flexible means permits the rigid zones to move independently with respect to each other while remaining physically connected or coupled. In a preferred embodiment, the rigid zones are physically and electronically coupled by the flexible means. In another preferred embodiment, the skin side of the rigid zones has a radius of curvature which approximates that of the body site to which the device is to be attached. A method of increasing the body or surface conformability of a rigid electrotransport device is described. The method involves the step of intentionally placing rigid subcomponents of the device in physically separate zones within the device. The rigid zones are separate and are coupled by flexible connector means.

  • Patent number: 6355025
    Abstract: The invention provides a method for adjusting, i.e., varying, the rate of delivery of a therapeutic agent through a body surface from an electrotransport assembly of the type which includes a predetermined, e.g., fixed, output electronic controller and a detachable therapeutic agent source. The method provides a plurality of therapeutic agent sources in which a single parameter or a series of parameters has been varied. The plurality of agent sources are supplied, one at a time, to the controller of the electrotransport assembly, so that together (i.e., source and controller) the agent delivery rate is varied.

  • Patent number: 6175763
    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.

  • Patent number: 6086572
    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.

  • Patent number: 5983130
    Abstract: An electrotransport agent delivery device for delivering a therapeutic agent through a body surface, and a method for increasing agent delivery efficiency, is provided. The device includes a current controller which delivers a pulsating electrotransport current and peak current density I.sub.max, I.sub.max being greater than a critical current density level I.sub.c above which the body exhibits a non-transitory higher agent delivery efficiency. Methods for increasing electrotransport delivery efficiency (E) of an agent through a body surface by creation of a higher agent delivery efficiency state are also provided.
