A steerable catheter (10) that includes a first elongated member (12), a second elongated member (14), and a distal tip (46) coupled to distal portions of the first and second elongated members. The first elongated member has at least one lumen (16) and a male or female element (24, 26). The second elongated member has the other of the male or female element, wherein the male element engaged with the female element. Relative movement between the first elongated member and the second elongated member causes a curveable portion of the catheter proximal from the distal tip to bend without uncoupling of the first elongated member and the second elongated member. A sheath (20) may be provided to encircle the first and second elongated members and define the curveable portion between the distal end of the sheath and the distal tip of the catheter.
