1. A handle assembly for supporting and controlling a steerable catheter, said handle assembly comprising:
a handle extending about a longitudinal axis from a proximal end to a distal end;
a lumen extending through said handle along the longitudinal axis from a receiving end disposed adjacent said proximal end to a distal tip extending outwardly from and terminating in spaced relationship with said distal end of said handle;
a pair of control wires interconnected to said distal tip and extending through said lumen and into said handle;
a lever assembly disposed at least partially within said handle and including a lever rotatable about a lever axis to control deflection of said distal tip of said lumen;
said lever assembly including a first gear assembly and a second gear assembly disposed in opposing relationship to one another and offset relative to the longitudinal axis;
said lumen passing between said first and second gear assemblies; and
each of said first and second gear assemblies interconnected to a respective one of said pair of control wires for individually pulling said control wires in response to rotation of said lever.
