  • Patent number: 9956403
    Abstract: An active transdermal medicament patch includes a planar substrate with a therapeutic face releasably retainable against the skin of a patient. A return electrode and a medicament matrix susceptible to permeation by medicament are secured at separated locations on the therapeutic face and electrically conductively engage the skin. A detector monitors iontophoretic medicament migration into the skin. An integrator operating on the output of the detector produces a running cumulative total of the amount of medicament delivered during a plurality of temporally non-contiguous therapy subsessions. A circuit breaker terminates medicament migration, when the output of the integrator equals a predetermined medicament quantity. A timer active during medicament migration stimulates a driver to operate a light-emitting diode in a distinct delivery confirmation mode during each a sequence of non-overlapping predetermined therapy subsessions, respectively.

  • Patent number: 8197844
    Abstract: A transdermal medicament patch includes a biocompatible substrate having a therapeutic face on one side configured for disposition against the skin of a patient, a biocompatible adhesive on the therapeutic face, a planar medicament matrix covering a portion of the therapeutic face, and a release liner covering the portion of therapeutic that is not obscured by the medicament matrix. An aperture formed through the release sheet affords direct access by medicament to the entire surface of the medicament matrix opposite from the therapeutic face of the substrate. An active electrode positioned between the medicament matrix and the therapeutic face of the substrate includes an electrically conductive backing layer positioned against the therapeutic face of the substrate and a pH-control layer covering less than all of the side of the backing layer opposite from the therapeutic face of the substrate.
