MR Guided Focused Ultrasound Treatment of Uterine Fibroids With Enhanced Sonication
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is a phase 3 study to determine the safety of the new features to the FDA approved ExAblate device using a new method to ablate fibroids deemed Enhanced Sonication.
Condition or disease
Uterine LeiomyomaUterine Fibroids
Device: ExAblate 2000
Uterine leiomyoma (fibroids) are the most common neoplasms of the female pelvis. These benign tumors are generally oval in shape, and often highly vascular. On T2 weighted MR imaging exams, or T1 exams with contrast, uterine fibroids are easily identifiable. They occur in 20-25% of women of reproductive age and can cause a variety of problems generally described as either bleeding or mass effects from the fibroid. InSightec has developed an Enhanced Sonication (ES) technique for the ablation of these fibroids. This mode of tissue ablation has been added to the already FDA approved ExAblate system. The goal of this ES technique is to provide an additional treatment tool that will enhance the treatment effect without additional risks while preserving ALL clinical features of the current commercially approved version.
