An apparatus includes a shaft, a balloon, a tip member, and a heating feature. The tip member is distal to the balloon and has a larger outer diameter than the shaft. The heating feature is operable to ablate tissue of the Eustachian tube contacting the balloon in the expanded state. The heating feature may include an illuminating element and a photosensitive coating on the balloon. Alternatively, the heating feature may include a thermal heating element that heats the balloon inflation fluid and thereby heats the wall of the balloon. Another apparatus includes a shaft, a tip member, and an electrode assembly. The electrode assembly includes a plurality of electrodes positioned along the shaft near the distal end, proximal to the tip member. The electrodes are spaced apart from each other along a longitudinal axis and are operable to apply RF energy to tissue to thereby ablate the tissue.

Apparatus and method for ablating Eustachian tube

An apparatus includes a shaft assembly and an electrode assembly at a distal end of the shaft assembly. The electrode assembly includes a first conductive segment extending along a first angular range at the distal end of the shaft assembly. The first conductive segment is operable to apply RF energy to tissue at a first polarity. The electrode assembly further includes a second conductive segment angularly spaced apart from the first conductive segment. The second conductive segment extends along a second angular range at the distal end of the shaft assembly. The second conductive segment is operable to apply RF energy to tissue at a second polarity such that the first and second conductive segments are operable to apply bipolar RF energy to tissue.

Variations of integral navigation controls may be used in conjunction with a medical instrument to provide navigation functions for an image guided surgery (IGS) system that is in communication with the integral navigation controls. In some variations, a medical instrument with integrated navigation wheels allows movement of a cursor of the IGS system along the x and y axis by scrolling the wheel, or allows selection, zooming, or other controls by combined clicking and/or scrolling of wheels, and may be sterilized or discarded along with the device. In some other variations, a control overlay may be temporarily attached to the medical instrument to provide additional controls, such as buttons or a pointing stick, and then removed and sterilized or discarded after a procedure. In each variation, inputs may be communicated via wire or wirelessly to an IGS system to provide navigation of images during a surgical procedure.

Medical instrument with integral navigation control features

A dilation instrument includes a body, a dilation catheter, a guide member, and a force sensor. The dilation catheter has an expandable dilator. The guide member extends distally from the body and is configured to guide movement of the expandable dilator. The force sensor is operatively connected to the guide member and is configured to sense a force imparted against the guide member for monitoring engagement with an anatomy of a patient.
