113: CSF Drain

Hydrocephalus is a condition where the cerebrospinal fluid (CSF) buildup in the cranium increases pressure on the brain. Current shunts drain CSF from the brain to other body parts where it can be reabsorbed; however, existing shunts fail after about two years. We developed a lumbar shunt that drained CSF from the lumbar spine to the venous system. A key feature of our design includes a ball-and-spring valve mechanism, which ensures precise flow regulation and prevents backflow, addressing a primary challenge of existing shunt systems. Our proposed lumbar shunt aims to provide a more durable, long-term solution to manage hydrocephalus, reduce complications and improve patient outcomes. Additionally, the minimally invasive nature of the shunt’s endovascular placement reduces surgical risks and promotes faster patient recovery. With advanced material selection and biocompatible design, our innovative shunt system seeks to improve patient’s quality of life while addressing critical shortcomings in existing treatments.
