Title:
MICRONEEDLE ARRAY ASSEMBLY, DRUG DELIVERY DEVICE AND METHOD FOR ADMINISTERING LIQUID ACROSS A BROAD AREA AT LOW PRESSURE
Document Type and Number:
WIPO Patent Application WO/2017/189258
Kind Code:
A3
Abstract:
A uniformity control membrane can be securely engaged against an upstream side of a microneedle array and configured so that resistance to flow through the uniformity control membrane is substantially greater than the resistance to flow through the microneedle array. These differences in flow resistance can facilitate uniform administration of a liquid formulation into the patient's skin across a broad area and at a relatively low pressure, such as by way of capillary action. The administration of the liquid formulation into the patient's skin across the broad area can result from the liquid formulation being administered by way of at least a majority of the microneedles of the microneedle array.
