Abstract: A handle assembly for controlling a steerable catheter includes a handle extending about a longitudinal axis from a proximal end to a distal end. A lumen extends through the handle to a distal tip extending outwardly from the distal end of the handle and a pair of control wires are interconnected to the distal end of extend the lumen. A lever assembly is disposed within the handle and includes a lever rotatable about a lever axis to control deflection of the distal end of the lumen. The lever assembly includes a first and second gear assembly disposed in opposing relationship to one another and offset relative to the longitudinal axis for allowing the lumen to pass therebetween. Each of the gear assemblies are interconnected to one of the pair of control wires to individually pull a respective one of the control wires in response to rotation of the lever.
