摘要：
A steerable catheter control mechanism comprises a rotatable driver and a deflection device responsive to the driver to selectively secure a pair of control wires. The control wires are positioned such that rotation of the driver reduces the effective deflection device radius while loading a selected wire in tension, thereby maintaining a relatively constant torque acting on the driver and minimizing operator fatigue. The deflection device is also responsive to the driver to selectively place one of the control wires in tension while maintaining the other wire in a static state thereby minimizing control wire fatigue.
