Hydrocephalus is a condition where excess cerebrospinal fluid (CSF) accumulates in the brain's ventricles, leading to increased pressure. To manage this, a shunt system is surgically implanted to drain excess fluid and regulate pressure. The shunt consists of a catheter placed in the brain’s ventricles, which connects to a longer catheter running down to the abdomen (typically the peritoneal cavity) to allow CSF drainage and absorption.

This design is inspired by a traditional zip tie, utilizing an interlocking pawl and notch system along the tail for secure fastening. The proposed improvement involves a single notch system that sets a preset tension, reducing complexity and minimizing potential biocompatibility issues. By simplifying the locking mechanism, the design ensures a secure and adjustable connection while maintaining compatibility with biomedical materials.
