What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean percentage change in target fibroid perfused volume |  | Baseline, 3 months, 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of adverse events | 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. | Procedure through 12 mo | 
| Percentage reduction in Symptom Severity Score (SSS) subscale of the Uterine Fibroid Symptom and Quality-of-Life (UFS-QOL) Questionnaire |  | Baseline through 12 months | 
| Rate of surgical reintervention for menorrhagia |  | through 12 months | 
| Return to normal daily activity |  | 2 weeks or until returned to normal activity | 
| Percentage reduction in Menstrual Pictogram score |  | through 12 months |
