Abstract:
Medical devices having an elongated steerable member are described herein. In one embodiment, a device includes an elongated body having a proximal section, a distal section, and a working lumen extending through the proximal and distal sections, a first coil having a distal portion, and a proximal portion, the proximal portion of the first coil being slidable relative to the proximal section of the elongated body, and being closer to a wall of the elongated body than to an axis of the elongated body, wherein a lengthwise portion of the distal portion of the first coil is anchored to the distal section of the elongated body, and a first steering wire located within a lumen of the first coil.
