A steerable member is disclosed generally having a steerable member for a medical apparatus, including a continuous, elongated body having a proximal section, a distal section, and a middle section between the proximal and distal sections, where the proximal section of the elongated body is less flexible than the distal section. At least one pull wire sheath extends through the proximal section and the middle section, but not through the distal section, and has a channel therethrough. A pull wire is disposed in the channel of the sheath and extends through the proximal section, middle section and distal section of the elongated body, the pull wire having a distal end affixed to a distal end of the elongated body, so that the distal section of the elongated body bends in response to a force applied to the proximal end of the pull wire.
