Apparatus, including a probe having a distal end insertable into a nasal sinus of a human patient, and a location sensor positioned within the distal end. A sinuplasty balloon is positioned on the distal end at a selected opening of the nasal sinus. A processor receives first signals from the location sensor while the distal end is inserted into the nasal sinus and prior to positioning of the balloon at the selected opening, and generates a first map of the sinus. The processor inflates the balloon when it is at the selected opening, so as to enlarge the selected opening, and subsequently deflates the balloon. The processor then receives second signals from the location sensor and generates therefrom a second map of the sinus. The processor registers the first map with the second map and generates from the registered maps a numerical increase in size of the selected opening.

Apparatus described herein includes a tube, shaped to define a tube lumen and including a distal portion that has a plurality of articulated sections. The apparatus further includes a ribbon that passes longitudinally through the tube lumen and is connected to a distalmost one of the articulated sections, and a control handle disposed at a proximal end of the tube, the control handle being configured to flex the distal portion of the tube by pulling the ribbon. Other embodiments are also described.

An endoscopy device is configured with a flexible cannula or tube for nasal insertion and has multiple parallel and adjacent lumens that provide sub-chambers configured to provide means to diagnose and treat Barrett's esophagus, such as by spray cryo-therapy with no further insertion of tubes. The lumens are configured to impart a small diameter with sufficient flexibility for nasal insertion into a patient's esophagus and accommodate a means any treatment modality. In the case of cryo-therapy, a lumen provides gas pressure relief, and is along the tube, with separate lumens for the delivery of a liquid freezing agent and an imaging means, which includes a source of illumination. Outer lumens may support guide wires used to steer the tube tip and aim the camera to determine the where to immobilize tip before the start of the treatment and/or to correct strictures formed in prior procedures.

A flexible endoscope insertion method includes: rotating a hollow organ by changing the body position to semilateral position or lateral position for observing the lateral wall of the lumen; turning the tip of the flexible endoscope to the lateral wall of the lumen by rotating the endoscope in the counter direction of the lumen; and retracting the organ with the endoscope itself by rotating the endoscope in the counter direction of the lumen. In other embodiments, the method includes: rotating a body cavity by changing the body position to the appropriate position for observing the lateral side of the organ; turning the tip of the flexible endoscope to the lateral side of the organ by rotating the endoscope in the direction of the lateral side of the organ; and retracting the organ with the endoscope itself by rotating the endoscope in the direction of the lateral side of the organ.
