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.
