Uterine Fibroid RF Ablation, Intrauterine Ultrasound, VizAblate

Brief summary

The primary objective of this study is to test the hypothesis that a minimum 75% volume radiofrequency ablation of fibroids associated with menorrhagia results in reduction of menstrual bleeding.

Interventions

DEVICEVizAblate Intrauterine Ultrasound-Guided RF Ablation

VizAblate enables a minimally invasive procedure to visualize, target and treat uterine fibroids using ultrasound visualization and RF energy.
