Video Summary

In this video presentation entitled "Design and Testing of High Resistance Ventricular Catheters, an Initial Feasibility Study," the aim was to investigate whether redesigning the inlet holes of ventricular catheters could prevent shunt malfunction. Five new catheter prototypes were developed using computational fluid dynamics and finite element analysis. These prototypes included a modified distal atrial catheter, a single U, a double U, a modified U, and a V. A testing apparatus was created to simulate CSF flow, and the prototypes were tested against a standard control catheter. The results showed varying improvements in flow control, with the modified U-shaped prototype performing the best. Overall, the study demonstrated the potential for high resistance ventricular catheters and the authors expressed their gratitude to the organizations involved in the research. No conflicts of interest were reported.
