The Mirabilis High-Intensity Focused Ultrasound (HIFU) Treatment System delivers therapeutic focused ultrasound energy to the uterus under integrated ultrasound imaging guidance to offer non-invasive treatment for uterine fibroids. The purpose of this clinical study is to assess the initial safety and performance of the Mirabilis HIFU Treatment System for transabdominal treatment of uterine fibroids in eligible women who are scheduled to undergo hysterectomy following treatment with the device.

Condition Intervention
Uterine Fibroids (Leiomyomas)
Device: Mirabilis High-Intensity Focused Ultrasound Treatment System

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Clinical Study of a Focused Ultrasound Device for Treating Uterine Fibroids and Menorrhagia

Primary Outcome Measures:
  • Evaluation of all adverse events encountered [ Time Frame: up to 6 months ] [ Designated as safety issue: Yes ]
    Safety of the intervention will be determined by evaluating the incidence and severity of adverse events and adverse device effects.

Secondary Outcome Measures:
  • Observation of tissue response via pathological assessment of fibroid specimens following hysterectomy and/or post-treatment magnetic resonance imaging (MRI) [ Time Frame: up to 6 months ] [ Designated as safety issue: No ]
    Preliminary efficacy of the intervention will be determined by evaluating the dimensions and position of nonviable tissue observed in each fibroid specimen via pathological processing following hysterectomy and/or by assessing the non-perfused volume (NPV) observed on post-treatment contrast-enhanced MRI.

Estimated Enrollment: 80
Study Start Date: January 2011
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Focused ultrasound treatment
Patients in this arm will receive fibroid treatment using the Mirabilis High-Intensity Focused Ultrasound Treatment System.
Device: Mirabilis High-Intensity Focused Ultrasound Treatment System
The intervention consists of a treatment session with the device, during which focused ultrasound energy is applied across the intact abdominal wall to ablate appropriately selected uterine fibroids under ultrasound imaging guidance.
