  • Patent number: 7031768
    Abstract: A planar disposable transdermal iontophoretic delivery system is disclosed which includes amounts of an oxidizable species and a reducible species connected by a common conductor forming a galvanic battery for serving as the sole source of power and control for the system, an amount of a therapeutic agent is provided to be driven through the skin of a patient solely through the use of the galvanic battery. The galvanic battery is provided with a lot-tested coulombic capacity rating to predict dosage.

  • Patent number: 7031769
    Abstract: An electrode assembly for use in an iontophoresis device for the transcutaneous administration of an active therapeutic species includes a base layer of conductive material which is consumed (oxidizes or reduces) preferentially to water, a first upper layer of sacrificial material coated on a first portion of the base layer wherein the sacrificial material is consumed preferentially to the conductive material of the base layer. A second upper layer of non-conducting material is coated on a second portion of the base layer, the second upper layer being spaced from the first upper layer, a narrow exposed linking area of the base layer material remaining therebetween. The exposed linking area of the base layer extends across the base layer. During operation of an associated iontophoresis device, the sacrificial material will be sequentially consumed; the first upper layer will be followed by the exposed linking area of the base layer which severs the base layer thereby breaking circuit continuity in the device.

  • Patent number: 6745071
    Abstract: A reliable, self-contained iontophoretic drug delivery system is disclosed which enjoys a long stable shelf life and which is easy for the user to activate and employ. This system includes a wearable iontophoretic device that is prepackaged as a complete self-contained unit which includes the active species or drug to be administered and counter ions. The system includes a provision for isolating moisture sources from the electrodes and from the power source during storage and provides a simple, user-friendly mechanism to connect the drug to be administered and counter ion reservoirs to the electrodes and the device to the skin of a user in order to activate the device circuit. All elements of the device are contained in a single outer package.

  • Patent number: 6653014
    Abstract: The capacity of an electro-chemical power source having an initial amount of an oxidizable material and an initial amount of a reducible material, is adjusted to a target capacity by altering the initial amount of one or both of the oxidizable material and the reducible material available to participate in the source by a technique selected from the group consisting of adding, removing and isolating a known fraction of the initial amount from the power source.
