Abstract
A catheter capable of articulating in two and three directions is provided. Articulation at the distal tip of the catheter is facilitated by applying selective tension on a steering wire disposed in a lumen that resides peripheral to a central working lumen. Tension on the steering wire through the peripheral lumen causes the catheter tip to bend while the central working lumen resists compression.
