The motion of the tube to all directions can be controlled with combined signals applied to four electrodes. For practical usage of the tip of active microcatheter for intravascular neurosurgery as shown in Figure 6.8, the tubular actuator of external diameter of 0.8 mm in the swollen state was attached to the end of catheter. The actuator is 2 cm long and the total length of the catheter is 1.5 m. Four conductive layers were made on the outside of the long...
