摘要：
Disclosed herein are steerable catheter assemblies that utilize various mechanisms to accomplish independent control of catheter flex magnitude and catheter flex direction to provide improved steerability of an attached catheter. Some embodiments include a catheter with two or more pull wires that flex the catheter and a control handle coupled to the catheter. The control handle can include a direction control coupled to the two or more pull wires such that adjustment of the direction control adjusts a direction of catheter flex by the two or more pull wires, and the control handle can include a magnitude control coupled to the two or more pull wires such that adjustment of the magnitude control adjusts the magnitude of catheter flex.
