Abstract
This project investigated the feasibility of fabricating miniaturized implantable duckbill valves for hydrocephalus treatment using cleanroom-free methods and alternative elastomeric materials. A benchtop pressure flow testing system was developed and validated to characterize valve performance.
While functional valves were not successfully fabricated outside of cleanroom conditions, the study identified key limitations in material compatibility and fabrication resolution that constrain low-cost manufacturing approaches.
