Abstract

There is an increasing need to develop devices for drug delivery to address ocular diseases such as glaucoma, age-related macular degeneration (AMD). Conventional ocular drug delivery devices are not capable of being refilled and doesn’t enable targeted drug delivery. But, MEMS devices help us to achieve the accurate drug delivery. The existing device have drawbacks like inconsistent performance of actuators, low cracking pressure of valves, getting damaged after repeated deliveries. By doing required modifications, the drug can be delivered to specific area at desired time and also it can deliver minor volumes of drug. In this paper, we design and simulate the micro pump with parylene bellows and check valves to overcome the existing drawbacks. By applying the required pressure, the drug will be released from reservoir to the targeted site with very accurate measures. With its high accurate delivery, the usage of drug volume can be reduced
