Described herein is a method for treating a narrowed region of a lumen in the ear or nose of a patient. The method includes advancing a catheter within the lumen such that a distal end of the catheter is positioned proximate to the narrowed region, filling a fillable member to expand the fillable member within the lumen, and generating at least one shock wave from at least one shock wave emitter. The at least one shock wave creates one or more fractures in a bony structure of the narrowed region of the lumen that dilate the narrowed region.

Described herein are low-profile electrodes for use with an angioplasty shockwave catheter. A low-profile electrode assembly may have an inner electrode, an insulating layer disposed over the inner electrode such that an opening in the insulating layer is aligned with the inner electrode, and an outer electrode sheath disposed over the insulating layer such that an opening in the outer electrode sheath is coaxially aligned with the opening in the insulating layer. This layered configuration allows for the generation of shockwaves that propagate outward from the side of the catheter. In some variations, the electrode assembly has a second inner electrode, and the insulating layer and outer electrode may each have a second opening that are coaxially aligned with the second inner electrode. An angioplasty shockwave catheter may have a plurality of such low-profile electrode assemblies along its length to break up calcified plaques along a length of a vessel.

A dilation assembly includes a shaft and a dilator coupled with the distal end of the shaft. The dilator includes a proximal end, a distal end, and a center portion positioned between the proximal end and the distal end. The center portion dilates from a first configuration to a second configuration. The center portion has a larger diameter than the proximal end and the distal end when the center portion is in the second configuration. At least one gripping feature is positioned on at least a portion of the exterior surface of the center portion. The gripping feature provides friction between the center portion and a bodily lumen when the center portion is in the second configuration.
