A Clinical Study to Evaluate Safety of the ExAblate 2100 UF V2 System in the Treatment of Symptomatic Uterine Fibroids

The first magnetic resonance-guided focused ultrasound (MRgFUS) treatment of uterine fibroid using the ExAblate 2000 system was performed in 2001. Since then, more than 5000 treatments were done in more than 60 different hospitals around the world. The experience accumulated in this novel treatment was collected by InSightec and implemented into software and hardware updates, clinical tips and guidelines, all aimed to improve the clinical results and their durability, while maintaining a high level of safety.

Based on extensive clinical experience and our internal research and development effort goals toward continuous improvement in ExAblate treatment safety and performance, limited changes have been made to the current ExAblate system. This modified ExAblate system version is designated as the ExAblate 2100 UF V2 system.

The modifications are believed to improve system's friendliness to the user, without introducing new risks or other issues of safety of the device, and should not have any negative impact on the safety or technical efficacy of the treatments for patients.

  • Patient is pre or peri-menopausal (within 12 months of last menstrual period)
  • Able to communicate sensations during the ExAblate procedure.
  • Uterine fibroids, which are device accessible
  • Fibroid(s) clearly visible on non-contrast MRI.
  • Fibroid(s) enhances on MR contrast imaging

Exclusion criteria

  • Women who are pregnant, as confirmed by serum/urine test at time of screening, or urine pregnancy test on the day of treatment
  • Uterine size > 24 weeks
  • Patients who are breast-feeding
  • Patients with active pelvic inflammatory disease (PID).
  • Patients with active local or systemic infection
  • Contraindication for MRI Scan:
  • Severe claustrophobia that would prevent completion of procedure in the MR unit
  • Weight greater than 250 IBS (113Kg)
  • Implanted ferromagnetic materials and/or devices contraindicated for MR scan
  • Known intolerance to MRI contrast agent (e.g. Gadolinium or Magnevist)
  • Any other contraindication for MRI Scan
  • Extensive abdominal scarring in the beam path

  • Known pelvic malignant or pre-malignant conditions
  • Intrauterine device (IUD) anywhere in the treatment path

Treatment and study plan

ExAblate 2100

Device

MR guided focused ultrasound

Primary outcomes

  1. Safety

    Time frame: 1 month

    Safety of ExAblate 2100 UF V2 will be determined by an evaluation of the incidence and severity of device- and procedure-related adverse events from the first visit through 1-month post-treatment.

Secondary outcomes

  1. Initial Efficacy

    Time frame: 1 month

    Efficacy will be evaluated by comparing the Non-perfused volume obtained from this study with that of the dataset supporting PMA approval using descriptive statistics
