Method for the treatment of joint diseases characterized by unwanted pannus
First Claim
Patent Images
1. A method for destroying the pannus in a joint of a subject, comprising the steps of:
- providing a transducer which produces a beam of ultrasound energy;
delivering said beam of ultrasound energy;
directing said beam of ultrasound energy on the pannus;
utilizing a multiphase array to focus a beam of ultrasound energy on the pannus; and
maintaining said beam on the pannus wherein the energy of said beam destroys the pannus.

9. A method for destroying the pannus in a joint of a subject, comprising the steps of:
-
providing a transducer which produces a beam of ultrasound energy; delivering said beam of ultrasound energy; directing said beam of ultrasound energy on the pannus wherein the energy of said beam raises the internal temperature of the pannus; utilizing a multiphase array to focus a beam of ultrasound energy on the pannus; and maintaining said beam on the pannus wherein the internal temperature of the pannus is elevated to a level which is sufficient to destroy the pannus by coagulating the pannus.

10. A method for destroying the pannus in a joint of a subject, comprising the steps of:
-
providing a transducer which produces a beam of ultrasound energy; delivering said beam of ultrasound energy; directing said beam of ultrasound energy on the pannus wherein gas bubbles form within the pannus; utilizing a multiphase array to focus a beam of ultrasound energy on the pannus; and maintaining said beam on the pannus wherein the gas bubbles destroy the pannus.
