Systems, devices and methods for providing therapy to an anatomical structure using high frequency pressure waves and/or cryogenic temperatures

1. A method of providing therapy to a paranasal sinus outflow tract, the method comprising:

coupling a therapeutic component to a shaft, the shaft having a distal end and an articulating portion; the therapeutic component spaced distally from the articulating portion;

inserting the therapeutic component into a paranasal sinus outflow tract, wherein the therapeutic component is inserted into the paranasal sinus outflow tract without the use of a guide wire, cannula or guide sheath;

emitting a high frequency pressure wave from the therapeutic component so as to destroy at least a portion of

the paranasal sinus outflow tract via the high frequency pressure wave.

2. The method of claim 1 wherein the high frequency pressure wave is between 24 kHz to 27 kHz.

3. The method of claim 1 wherein the high frequency pressure wave comprises a radio frequency pressure wave.

4. The method of claim 1 wherein the high frequency pressure wave comprises an ultrasonic frequency pressure wave.

5. The method of claim 1 further comprising:

moving the articulating portion of the shaft from a first position to a second position;

engaging the distal end of the shaft with tissue proximal to the paranasal sinus outflow tract, wherein the articulating portion of the shaft remains in the second position when the distal end of the shaft engages the tissue proximal to the paranasal sinus outflow tract.

6. The method of claim 5 wherein the tissue comprises scar or granulation tissue.

7. The method of claim 5 further comprising tracking the location of the distal end of the shaft with a location sensor.

8. The method of claim 1 further comprising delivering a therapeutic fluid to the paranasal sinus outflow tract.

9. The method of claim 1 wherein the paranasal sinus outflow tract comprises a frontal sinus.

10. The method of claim 1 wherein the high frequency pressure wave destroys at least a portion of the sinus outflow tract so as to enlarge the sinus outflow tract.

11. The method of claim 10 the sinus outflow tract is enlarged by the high frequency pressure wave so as to restore normal mucus drainage through the tract.

12. A method of providing therapy to a paranasal sinus outflow tract, the method consisting:

coupling a therapeutic component to a shaft, the shaft having a distal tip and an articulating portion spaced proximally from the distal tip, the therapeutic component disposed between the articulating portion and the distal tip;

inserting the therapeutic component into a paranasal sinus outflow tract, wherein the therapeutic component is inserted into the paranasal sinus outflow tract without the use of a guide wire, cannula or guide sheath;

emitting a high frequency pressure wave from the therapeutic component, the pressure wave operable to destroy a portion of the paranasal sinus outflow tract via the high frequency pressure wave;

halting the step of emitting; and

withdrawing the therapeutic component from the paranasal sinus outflow tract.

13. The method of claim 12 wherein the sinus tract comprises scar and granular tissue and wherein the step of emitting a high frequency pressure wave so as to destroy a portion of the paranasal sinus outflow tract destroys scar and granular tissue.

14. The method of claim 12 wherein the step of emitting a high frequency pressure wave so as to destroy a portion of the paranasal sinus outflow tract enlarges the sinus outflow tract, the enlarged outflow tract configured to restore normal mucus drainage through the tract.
