Title:
SYSTEM AND METHOD FOR MAKING MICRONEEDLES
Document Type and Number:
WIPO Patent Application WO/2019/203888
Kind Code:
A3
Abstract:
Systems and methods for creating microneedle arrays capable of delivering a suitable drug dosages to subjects are provided. In one aspect, a method comprises creating at least one forming mold using laser ablation in a cross-over line pattern. The method further comprises casting a first material onto the at least one forming mold to create at least one microneedle mold. The method further comprises casting a second material onto the at least one microneedle mold to create at least one hollow microneedle.
