Abstract
Steerable catheters include cam and follower mechanisms that provide independent control of catheter flex magnitude and catheter flex direction to provide improved steerability of an attached catheter. In certain embodiments, the steerable catheter assemblies include two or more pull wires that flex the catheter, and a control handle coupled to the catheter having a direction control and a magnitude control, both of which are operably coupled to the two or more pull wires by the cam and follower mechanism. In embodiments disclosed herein, the cam and follower system can be modified to achieve particular catheter control.
