Abstract

Methods and apparatus are provided for non-invasively treating patent foramen ovale using an ultrasound imaging system and a high intensity focused ultrasound system to selectively target high intensity ultrasound energy on either or both of a patient's septum primum or septum secundum.

Independent Claims | See all claims (11)

  1. 1. A method of treating patent foramen ovale comprising: providing a catheter having a distal portion housing an ultrasound imaging system and a high intensity focused ultrasound system disposed in alignment with the ultrasound imaging system; disposing the distal portion of the catheter within a patient's body lumen; operating the ultrasound imaging system to generate an image of a portion of cardiac tissue; and operating the high intensity focused ultrasound system, guided by the image, to heat or ablate either or both of the patient's septum primum or septum secundum.
