Abstract

An apparatus can include: (1) a steerable tube, having a proximal section, a distal section, and a central longitudinal axis, the tube defining a primary lumen and two secondary lumens; (2) two wires, each extending from the distal section proximally through a respective secondary lumen; (3) a handle, coupled to the proximal section, and including a steering knob that is coupled to the wires such that rotation of the knob adjusts a degree of tension in the wires; (4) a pull ring coupled to the distal section of the tube such that the pull ring circumscribes the longitudinal axis at the distal section of the tube, and defining two recesses, a distal end portion of each wire being disposed in a respective one of the recesses; and (5) at least one cap, bridging the recesses and the distal end portion of the wires. Other embodiments are also described.
