Patent attributes
In one embodiment an apparatus for insertion in a body cavity (e.g., an endoscope) may include an elongate assembly, an instrument tip disposed at a distal end of the elongate assembly, and a terminal base disposed at a proximal end of the elongate assembly. The elongate assembly may include a first peripheral tube, a second peripheral tube spaced apart from the first peripheral tube and a plurality of collar members. Each collar member may include a first channel grasping the first peripheral tube, and a second channel grasping the second peripheral tube. The collar members may be spaced apart from one another along a length of the elongate assembly such that adjacent collar members do not contact one another. The terminal base may include a first control fitting attached to the first peripheral tube and a second control fitting attached to the second peripheral tube. The first control fitting may be configured to apply tension to the first peripheral tube. The second control fitting may be configured to apply tension to the second peripheral tube.
