Abstract:
1. A transdermal patch having an on-board energy storage device for coupling to an external source of power in order to store a charge in the energy storage device, comprising: a drug source for transdermal delivery of a drug through a skin of a user; a dermal contact layer positioned to maintain the drug source in contact with the skin; a removable carrier; an electrically-actuatable porator supported by the carrier for movement therewith while the dermal contact layer remains in position for transdermal delivery of the drug and being removably seated so as to substantially or completely overlie the drug source; the energy storage device being supported for selective electrical connectivity to the porator in response to movement of at least a portion of the carrier so as to actuate the porator by discharging the charge stored in the energy storage device free of any concurrent connection to the external source of power, the porator being arranged so as to be withdrawn from its seat overlying the drug source with continued movement of the carrier; and conductive contact terminals extending from the energy storage device, the contact terminals being connectable to the external source of power so as to couple the electric potential from the external source of power with the energy storage device.
