An introducer has a shaft with a central lumen, a control handle with adeflection assembly,and a tensile member with a distal portion extending along opposing sides ofwithin the shaft and aproximal portion extending within the control handle. The deflection assemblyhas a deflectionarm, and a rotatable member rotationally coupled to the deflection arm,wherein the rocker memberhas at least one pulley engaged with the proximal tensile member portion.Rotation of thedeflection arm in one direction draws the proximal tensile member portion fordeflecting the shaft.
