Electronic card for transdermal drug delivery and analyte extraction
First Claim
1. A device for facilitating transdermal passage of a substance through skin of a subject, comprising:
- one or more electrodes, which are adapted to be placed at respective sites on the skin; and
a control unit, which is adapted;
to drive at least some of the one or more electrodes to apply to respective ones of the sites on the skin a current capable of ablating stratum corneum epidermidis of the skin, so as to facilitate transdermal passage of the substance through the skin, to designate at a first time a first number of the one or more electrodes to drive to apply the current, responsive to a desired rate of passage of the substance during a first time period, and to designate at a second time a second number of the one or more electrodes to drive to apply the current, responsive to a desired rate of passage of the substance during a second time period, the second number being different from the first number.

Abstract
Devices for facilitating transdermal passage of materials are provided. In a preferred embodiment, a device for delivering a substance to skin of a subject is provided. A substance storage unit is adapted to store the substance. An analysis unit is adapted to receive a portion of a body fluid of the subject, to analyze the portion, and to generate a signal responsive to the analysis of the portion. One or more electrodes are adapted to be placed at respective sites on the skin. A substance delivery unit is adapted to receive the signal, and, responsive thereto, to drive at least some of the one or more electrodes to apply to respective ones of the sites on the skin a current capable of ablating stratum corneum epidermidis of the skin, so as to facilitate delivery of the substance from the storage unit through the skin at the respective ones of the sites.
