Brief Summary:
The purpose of this study is to establish the effectiveness and confirm the safety of the VizAblate System in the ablation of large (> 5 cm) symptomatic uterine fibroids.

Condition or disease Intervention/treatment Phase
Leiomyoma Uterine Fibroids Menorrhagia Device: VizAblate System Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 6 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Symptom Effectiveness Study of VizAblate® Intrauterine Ultrasound-Guided RF Ablation (IUUSgRFA) in the Ablation of Large Uterine Fibroids
Study Start Date : June 2012
Actual Primary Completion Date : June 2014
Actual Study Completion Date : June 2014

Arm Intervention/treatment
Experimental: VizAblate intervention
VizAblate System with subject serving as her own control
Device: VizAblate System
VizAblate enables a minimally invasive procedure to visualize, target, and ablate uterine fibroids using intrauterine ultrasound and radiofrequency (RF) energy

Primary Outcome Measures :
  1. Mean percentage change in target fibroid perfused volume [ Time Frame: Baseline, 3 months, 12 months ]

Secondary Outcome Measures :
  1. Number of adverse events [ Time Frame: Procedure through 12 mo ]
    Procedure safety will be assessed by recording all adverse events that occur on the day of the procedure. Longer-term safety will be assessed by recording at each follow-up visit any untoward medical occurrence since baseline. Each adverse event will be assessed for severity and relationship to study device.

  2. Percentage reduction in Symptom Severity Score (SSS) subscale of the Uterine Fibroid Symptom and Quality-of-Life (UFS-QOL) Questionnaire [ Time Frame: Baseline through 12 months ]
  3. Rate of surgical reintervention for menorrhagia [ Time Frame: through 12 months ]
  4. Return to normal daily activity [ Time Frame: 2 weeks or until returned to normal activity ]
  5. Percentage reduction in Menstrual Pictogram score [ Time Frame: through 12 months ]
