Abstract: An endoscope device comprises a handle, a shaft projecting from the handle, a flexible tip coupled to the distal portion of the shaft; and first and second pull wires extending from the handle portion through the shaft portion and coupled to the flexible tip. The handle portion includes a control wheel assembly coupled to proximal ends of the first and second pull wires. The control wheel assembly comprises a control wheel having a disc-shaped body rotationally mounted within the handle and having an outer perimeter and a first surface and first and second pull wire troughs provided on the first surface for receiving the proximal ends of the first and second pull wires, respectively. Positioning of the first and second pull wires within the first and second pull wire troughs is performed independently to provide accurate tensioning of the first and second pull wires during assembly of the endoscope device.

Abstract: Methods and apparatus for positioning a elongate hollow member at a desired location in a body in a medical procedure are provided. A position marker is removably disposed within a sheath. The sheath may be disposable. The sheath and enclosed position marker may be inserted into a lumen of a member to be positioned. The position in space of the position marker may be monitored by a position sensor to provide real-time information regarding a position of the member. The spatial relationship between the position marker and member may be fixed by securing the mounting member to the sheath and securing the sheath to the member.
