An introducer (10) has a shaft (12) with a central lumen (18), a control handle (16) with a deflection assembly (24), and a tensile member (22) with a distal portion extending along opposing sides of within the shaft (12) and a proximal portion extending within the control handle (16). The deflection assembly (24) has a deflection arm (36), and a rotatable member (38) rotationally coupled to the deflection arm (36), wherein the rocker member (38) has at least one pulley (47) engaged with the proximal tensile member (22) portion. Rotation of the deflection arm (36) in one direction draws the proximal tensile member (22) portion for deflecting the shaft (12).
