Abstract
A catheter handle includes a steering controller to be used in conjunction with a steerable catheter shaft, and a steering tendon tensioning device. The operator deflects the profile of a distal-end region of the catheter by rotating the steering controller. Spring devices located on the steering tendons maintain the steering tendons in tension during manipulation of the steering controller. A locking device locks the steering controller in place relative to the handle.
