Abstract: A catheter includes an electromechanical polymer (EMP) actuator disposed in a steerable tip at the distal end of the catheter. When activated, the EMP actuator deflects the steerable tip through an angle between 0 and 270 degrees, thus permitting the operator to steer the steerable tip through the vasculature. The steerable tip also has at least a first relatively stiff region and a second relatively flexible region, and the EMP actuator is provided next to the first relatively stiff region so that the steerable tip may toward the flexible region when activated. In one implementation, an external interface allows a user to select by name one of many sets of control signals, with each set of control signals being signals calibrated for configuring the catheter to mimic a known catheter.

Abstract translation: 导管包括机电聚合物（EMP）致动器，其设置在导管远端处的可转向尖端中。 当激活时，EMP致动器将可操纵的尖端偏转在0和270度之间的角度，从而允许操作者引导可操纵的尖端通过脉管系统。 可转向尖端还具有至少第一相对较硬的区域和第二相对柔性的区域，并且EMP致动器设置在第一相对较硬的区域旁边，使得可操纵的末端可以在被激活时朝向柔性区域。 在一个实现中，外部接口允许用户通过名称来选择许多组控制信号中的一个，每组控制信号被校准用于配置导管以模拟已知的导管。
