    Abstract: Disclosed is a device for causing the transdermal flux of a per meant into a subject via at least one formed pathway through a skin layer of the subject. The device comprises a delivery reservoir comprising: i) a non-biodegradable matrix having a bottom surface and defining a plurality of conduits therein the matrix, at least a portion of the plurality of conduits being in communication with the bottom surface; and ii)an undissolved hydrophilic per meant disposed therein at least a portion of the plurality of conduits of the matrix, wherein the hydrophilic per meant can come in contact with subcutaneous fluid from the subject when the bottom surface of the matrix is positioned in fluid communication with the at least one formed pathway. Also disclosed are systems and methods for causing the transdermal flux of a per meant into a subject via at least one formed pathway through a skin layer of the subject.

    Abstract: The invention provides for a transdermal drug delivery device for forming a drug delivery patch system comprising: a) an actuator comprising: i) an outer body defining a top of the actuator, the outer body containing a cavity; ii) a controller board comprising driving electronics and a battery, the controller board being positioned within the cavity; and iii) an interface connection port for receiving a porator array, the interface connection port containing an anode and a cathode; b) the porator array comprising: i) a top surface, with a removable adhesive attached to the top surface, the top surface containing two concentric electrical contact rings for contacting the interface connection port at the anode and the cathode upon removal of the adhesive layer; ii) a bottom surface comprising a tissue interface membrane, the tissue interface membrane further comprising a substrate with at least one porator contained on or within the substrate, the bottom surface further comprising an adhesive layer for attaching the porator array to a tissue membrane; and iii) an extension tab laterally and removably attached to the bottom surface, the extension tab including an adhesive applied on the bottom thereof, thereby allowing the extension tab to remain on the tissue membrane upon removal of the porator array; and iv) a release liner removably attached to the bottom surface; and c) a reservoir patch attached to the extension tab, the reservoir patch being applied to the microporated area of the tissue membrane after poration. The invention also provides for methods of making and methods of using the same.

    Abstract: A system and method for determining a duration that a patient has been experiencing a medical condition compares characteristics of fluorescent emissions from a target tissue to expected characteristics. In a system and method embodying the invention, a target tissue is illuminated with excitation light, and fluorescent emissions generated by the target tissue in response to the excitation light are detected. Different characteristics of the fluorescent emissions, including the fluorescent emission intensity or the fluorescent lifetime may be determined. The determined characteristics of the detected fluorescent emissions are then compared to expected characteristics of the fluorescent emissions. The amount that the detected fluorescent characteristics deviate from the expected fluorescent characteristics is used to determine a duration that a patient has been experiencing a medical condition. In some instances, the backscattered portions of the excitation light may also be used to make the determination.
