MICRONEEDLE ARRAY ASSEMBLY AND FLUID DELIVERY APPARATUS HAVING SUCH AN ASSEMBLY

Abstract:

A microneedle array assembly includes a microneedle array that has a plurality of microneedles. A distribution manifold includes a fluid supply channel that is coupled in flow communication to a plurality of resistance channels. Each of the resistance channels are coupled in flow communication to a respective one of the microneedles of the microneedle array. The resistance channels have a resistance value to a fluid flow through each resistance channel that is in the range between about 5 times greater to about 100 times greater than a resistance to the fluid flow through the supply channel.
