Abstract: A system operable to allowing viewing of a physical subject with information regarding at least an item separate from the subject overlaid thereon. The system includes a viewscreen. The system is further able to determine the position of the item relative to the subject.

Abstract: A device for dilating an Eustachian tube of a patient including an inner member, an inflation fluid supply tube, a balloon, and a coupler. The inner member includes a lumen fluidly open at distal and proximal ends. The inner member has a distal portion, a proximal portion, and a central portion. The inflation fluid supply tube is fixedly disposed around the central. The inflation fluid supply tube has an opening disposed between first and second ends. A proximal portion of the inner member extends through the opening and the opening is fluidly sealed against an exterior surface of the inner member. The coupler is configured to selectively couple the inflation fluid supply tube to an endoscope. The coupler is configured to engage against an exterior surface of the inflation fluid supply tube. The coupler is disposable between the first end and the opening of the inflation fluid supply tube.

Abstract: A treatment system including a therapy device for treating soft tissue inflammation of the ear. The device includes an inflation fluid supply tube, an inner member, and a balloon. The inflation fluid supply tube has an inflation lumen extending longitudinally therethrough and an opening disposed between opposing first and second ends. The inner member is formed of a shape memory material and defines distal, proximal, and center portions. The center portion extends longitudinally within the inflation fluid supply tube. The distal portion extends distally from the first end and the proximal portion extends through the opening. A lumen of the inner member is fluidly open at and between distal and proximal ends. The balloon is disposed along the distal portion, and is fluidly coupled to the inflation lumen. A tracking device for image guided navigation can be attached to the distal portion of the inner member.
