Abstract
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.
Claims21
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.
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.
