A control system and method are provided for control of a steerable catheter, the catheter including at least two control wires, a distal end of each of the control wires being coupled to the catheter at a distal region thereof, the control system comprising: a housing coupled to the catheter; a slide assembly positioned within the housing and operable to translate linearly therein; a proximal portion of each of the at least two control wires being positioned through the slide assembly; and a control knob rotatably coupled to the housing for linearly translating the slide assembly, thereby enabling the slide assembly to separately manipulate each of said at least two control wires to effect a change in a deflection of said catheter. Rotation of the control knob in a first rotational direction causes distal movement of the slide assembly in a first linear direction causing the slide assembly to tension one of said at least two control wires thereby effecting a change in the deflection of said catheter in a first deflection direction and wherein rotation of the knob in a second rotational direction causes proximal movement of the slide assembly in a second linear direction causing the slide assembly to tension the other of said at least two control wires thereby effecting a change in the deflection of said catheter in a second deflection direction.
