ABSTRACT
As it is impossible for an active catheter with a very small space to accommodate overmany lead wires in minimally-invasive surgery, a matrix network system is presented, in this paper, to control SMA actuators using minimum lead wires. Pulse current is adjusted by pulse width modulation (PWM) signals from the single-chip processor. In addition, multiple SMA actuators' cooperation helps the active catheter to succeed in guiding motion.
