Three-dimensional microfluidics devices for the delivery of actives

Abstract:

A transdermal delivery device includes a film having first and second outwardly facing major surfaces; at least one liquid reservoir contained within the film; at least one microfluidic channel having a transverse dimension between about 100 nm and 0.5 mm disposed within the film and in fluid communication with the at least one liquid reservoir; and at least one outlet port associated with at least one microneedle operatively connected to the first outwardly facing major surface of the film in fluid communication with the at least one microfluidic channel.
