Claim 7:
8. A medical device, comprising:
a flexible elongate tube having a proximal end, a distal end, a longitudinal axis extending along a length of the tube, an outer surface, and a distal portion proximal to the distal end that extends longitudinally along a portion of the length of the tube, the distal end configured to access an opening of a body lumen;
a plurality of marker bands configured to visually indicate a location and orientation of the device, the plurality of marker bands comprising a distal marker band disposed about the flexible elongate tube at the distal end;
a plurality of wire lumens extending from the distal end of the tube toward the proximal end of the tube, the wire lumens radially offset from and substantially parallel with the longitudinal axis, wherein at least a portion of each of the plurality of wire lumens is in the form of a longitudinal open channel having a length that extends along a length of the distal portion and is radially open along the length of the outer surface along the distal portion;
a central lumen extending from the distal end toward the proximal end of the tube; and
a plurality of wires, each wire extending along a respective wire lumen, each wire substantially flush with the outer surface of the flexible elongate tube along the length of the distal portion, and a portion of each wire configured to extend radially externally to the respective wire lumen along the portion of the wire lumen that is radially open along the outer surface;
wherein the plurality of wires is configured to bend the distal end of the flexible elongate tube by proximally translating one or more of the plurality of wires such that a distal end of the one or more translated wires pulls proximally on the distal end of the flexible elongate tube, causing the distal end of the flexible elongate tube to bend in a direction of the one or more wires.
