Abstract: A steerable catheter comprises a transducer that is situated at a flexible distal end, and is coupled to the handle of the catheter via an insertion tube. The flexible distal end is controlled by a plurality of articulation pull-cables that extend from an articulation control device in the handle to the far end of the distal end, such that when one articulation pull-cable is pulled, and the opposing articulation pull-cable is slackened, the flexible distal end bends in the direction of the tensioned articulation pull-cable. To minimize pull-resistance over time, while still providing insertion-tube flexibility, inserts having pull-cable lumens are situated in the insertion tube to isolate each articulation pull-cable from each other, and from other cables that couple the transducer to the handle.
