Sonography Guided Transcervical Ablation of Uterine Fibroids (SONATA)


If you’re tired of heavy periods due to uterine fibroids, you may qualify for a new clinical research study. The study is for the Sonata™ System – an investigational device that targets fibroids and preserves the uterus through an incision-free, outpatient procedure.

Unlike open surgery or laparoscopy, the Sonata System is designed to access the inside of the uterus without any incisions. The Sonata System uses sonography to locate and target the individual fibroids, and radiofrequency (heat) energy to treat the fibroids. Unlike hysterectomy, which removes the entire uterus, the Sonata System targets just the fibroids, thus preserving the uterus. This study will establish if the heat energy can make fibroids shrink and reduce fibroid-related symptoms.

Participants in the study will receive treatment and all study-related care at no cost. Following your treatment, you will be asked to meet with your study doctor up to 5 times over the next 12 months. These visits are an important part of the study, as they allow your doctor to closely monitor your results and overall experiences. You will receive a payment upon completion of many of these visits to compensate you for your time and travel.
