Abstract
Disclosed herein are steerable catheter assemblies and methods of steering catheters that utilize ball and socket mechanisms to accomplish independent control of catheter flex magnitude and catheter flex direction. Some embodiments include a catheter with two or more pull wires that flex the catheter, a first ball, a socket coupled to the first ball to form a ball and socket assembly, and an adjustment member coupled to the ball and socket assembly, such that the adjustment member is movable axially and rotationally relative to the ball and socket assembly. Two or more pull wires are connected to the socket, and the adjustment member engages the socket such that movement of the adjustment member adjusts the position of the socket relative to the first ball to thereby flex the catheter with the pull wires.
