1. A microneedle array assembly, comprising:
a microneedle array comprising a plurality of microneedles; and
a distribution manifold comprising a supply channel coupled in flow communication to a plurality of resistance channels,
each resistance channel coupled in flow communication to a respective one of a plurality of outlet channels, and
each outlet channel coupled in flow communication to a respective one of the plurality of microneedles,
wherein a resistance value to a fluid flow through each resistance channel of the plurality of resistance channels is in a range between about 5 times greater to about 100 times greater than a resistance to the fluid flow through the supply channel.
