Abstract
One-way duckbilled valves acting as artificial arachnoid granulations (aAGs) serve as a promising alternative to existing shunt systems utilized in cerebrospinal fluid (CSF) drainage for hydrocephalus. Video analysis was utilized to measure the valve opening’s maximum deformation under a range of different flow rates and fluids/viscosities and ensure that its dimensions remain within acceptable limits.
Additional experiments were performed to measure the valve opening’s total deformation in a cyclic droplet test and to visually measure the velocity of the valve’s fluid output.
