ExAblate UF V2 System for the Treatment of Symptomatic Uterine Fibroids
The purpose of this study is to evaluate the safety and ablation efficacy of the ExAblate UF V2 System when treating symptomatic uterine fibroids.
The ExAblate System is a medical device that involves a focused ultrasound system and an MRI scanner. ExAblate delivers a pulse of focused ultrasound energy, or sonication, to the targeted tissue. In this particular study, the targeted tissue is uterine fibroids. Each sonication is used to heat small spots in the fibroid much like a magnifying glass can be used to focus light to heat a spot. The heat created kills a portion of the fibroid with the goal of decreasing or eliminating uterine fibroid-related symptoms. Repeated sonications are performed until the entire fibroid is treated or the treated volume is determined to be appropriate.
The ExAblate system is commercially approved in the United States to treat symptomatic uterine fibroids.
The ExAblate UF V2 System is an experimental device and is being investigated in this study. While similar to the commercial system, the ExAblate UF V2 device includes the following major changes, among others, which are intended to improve device performance and safety:
- Up and down movement of the ultrasound transducer, in an attempt to improve fibroid treatment by moving the ultrasound focal point within the targeted fibroid.
- Ultrasound energy can be turned off for a specific area in an attempt to minimize amount of energy passing through sensitive areas of the body.
