1. A control handle for a steerable transluminal device, the control handle comprising:
a housing defining a longitudinal axis extending in distal and proximal directions;
pull wires that extend from a distal end of the housing and into the steerable transluminal device and that extend along an axial length of the steerable transluminal device and that are operable to effect flexion of the steerable transluminal device;
a flex control member operable to control tension on the pull wires to adjust a magnitude of radial flexion of the steerable transluminal device;
a position control member operable to control tension on the pull wires to adjust a circumferential angle in which the radial flexion of the steerable transluminal device is directed;
a cam member that is movable axially relative to the housing and also movable rotationally about the longitudinal axis relative to the housing;
at least one follower engaged with the cam member such that the at least one follower moves relative to the control handle in response to movement of the cam member relative to the housing;
wherein the pull wires are coupled to the at least one follower;
wherein rotation of the flex control member causes axial adjustment of the cam member; and
wherein the position control member is fixed relative to the cam member and rotation of the position control member causes rotational adjustment of the cam member.
