1. A method for treating a narrowed region of a lumen in the ear or nose of a patient, the method comprising:
advancing a catheter within the lumen such that a distal end of the catheter is positioned proximate to the narrowed region, the distal end of the catheter comprising at least one shock wave emitter that is surrounded by a fillable member;
filling the fillable member to expand the fillable member within the lumen; and
generating at least one shock wave from the at least one shock wave emitter, the at least one shock wave creating one or more fractures in a bony structure of the narrowed region of the lumen that dilate the narrowed region.
 
20. A device for treating a narrowed region of a lumen in the ear or nose of a patient, the device comprising:
an elongated tube;
at least one shock wave emitter, the at least one shock wave emitter configured to generate at least one shock wave along a working direction;
at least one imaging sensor oriented to capture images along the working direction; and
a fillable member sealed to a distal end of the elongated tube and surrounding the at least one shock wave emitter and the at least one imaging sensor, the fillable member fillable with a conductive fluid.
