ABSTRACT:
An elongated flexible probe has a tubular fluid-controlled bending neck. A connector joins the bending neck to a flexible elongated insertion tube formed of an elastic tubing on which a filament braid is disposed. The braid is nearly circumferential, i.e., with a high braid angle, so that internal pressure in the insertion tube will not expand it laterally, but the braid will permit axial movement. This accommodates pumping action of the bending neck on optical fibers and wires that pass from the distal tip back through the bending neck, connector, and insertion tube.
