Abstract: The present invention comprises a transdermal drug delivery device for delivering a pharmaceutically active agent comprising a reservoir comprising a releasably stored dosage of the pharmaceutically active agent and a substantially continuous, translucent inorganic barrier layer adjacent to at least a portion of the reservoir. The present invention also comprises a method of drug delivery to a mammal using such devices.

Abstract: A flexible barrier assembly having a flexible visible light-transmissive substrate having a Tg greater than or equal to that of heat-stabilized polyethylene terephthalate (“HSPET”) overcoated with a first polymer layer having a Tg greater than or equal to that of HSPET and further overcoated with at least two visible light-transmissive inorganic barrier layers separated by at least one second polymer layer having a Tg greater than or equal to that of HSPET can be used to mount, cover, encapsulate or form moisture- and oxygen-sensitive articles such as organic light emitting devices and light valves.
