  7. Abstract:
  8. Hydrocephalus is a desease which causes by unnatural accumulation of cerebrospinal fluid in the brain ventricles. One of the most convenient ways to treat hydrocephalus disease is to use a brain shunt which consists of ventricular catheter, valve and distal catheter. Ventricular catheter obstruction is the main reason for shunt replacement in the human brain. This project attempts to remove obstruction of the ventricular catheter by mechanical forces. For this purpose, a magnet and a variable magnetic field suggested to apply mechanical force on a brush sliding on the shunt. On the inner surface of the ring-shaped magnet, brushes have been embedded and the magnet is placed on the outer surface of the ventricular catheter. By moving the magnet, the brushes sweep the outer surface of the catheter and remove the obstruction of the ventricular catheter. To prove the efficiency of this design, a model of brain ventricular is made and the experimental tests are performed on themagnified physical model and the flow-height diagrams for before and after artificial obstruction were extracted and the results are analyzed. By comparing these diagrams the ability of this design in unblocking the ventricular catheter CSF shunt is shown
