A catheter control handle for precise spatial placement of a working catheter tip in an organ or vessel of interest is presented that is readily operable with one hand and uses a single operating knob in conjunction with a single control wire connected in the distal working catheter tip area in a manner such that longitudinal translation of the knob produces distal catheter tip deflection and rotation of the knob produces rotation of the deflected tip. The longitudinal translation of the control knob deflects the catheter tip by displacing the proximal portion of the catheter relative to the control wire and the rotation of the control knob applies rotational torque to the control wire.
