ABSTRACT:
A handle/actuator for use with a steerable catheter having a tip assembly and four pull cables for bending said tip assembly, comprises a housing containing rotary and linear actuators. The rotary actuator is in the form of a wheel rotatably supported in said housing with a portion of said wheel being accessible from the exterior of said housing. Two of the pull cables are anchored to the wheel such that clockwise rotation of the wheel applies tension to one pull cable and counter-clockwise rotation of the wheel applies tension to the second pull cable. The linear actuator comprises a slider mounted in said housing and means exterior of the housing for moving the slider linearly. The third and fourth pull cables are anchored to the slider such that linear movement of the slider in one direction applies tension to the third cable and linear movement of the slider in the opposite direction applies tension to the fourth cable.
