Abstract
Disclosed herein are steerable catheter assemblies and methods of steering catheters that utilize driver and follower mechanisms to accomplish independent control of catheter flex magnitude and catheter flex direction. Some embodiments include a catheter with a first pull wire and a second pull wire that flex the catheter, a control handle coupled to the catheter, a first follower connected to the first pull wire, a second follower connected to the second pull wire, and a driver disposed in the control handle and coupled to the first and second followers. The rotation of the driver coupled to the control handle moves the first and second followers in opposite directions, and axial movement of the driver moves the first and second followers in the same direction.
