Summary

The purpose of this study is to demonstrate the safety and effectiveness of radiofrequency ablation (RFA) using the Halt System for the treatment of patients with symptomatic uterine fibroids.

Eligibility Criteria

Inclusion Criteria

  • Are premenopausal and ≥ 25 years old
  • Have symptomatic uterine fibroids
  • Have a uterine gestational size ≤14 weeks as determined by pelvic exam
  • Have ≤ 6 (six) treatable fibroids in whom no single fibroid exceeds 7 cm in any diameter as measured by ultrasound or magnetic resonance imaging (MRI). Only Fibroids greater than 1cm in diameter should be treated in this study
  • Have a total uterine fibroid volume that does not exceed 300cc on ultrasound or contrast-enhanced MRI evaluation
  • Have clinical menorrhagia as indicated by menstrual blood loss of ≥160 mL to 500 ml during one baseline cycle or two baseline cycles within three months prior to treatment
  • Have a history of at least 3 months of menorrhagia within the last six months
  • Desire uterine preservation
  • Do not desire current or future childbearing
  • Have a normal coagulation profile international normalized ratio (INR), Platelets, Prothrombin Time, and Partial Thromboplastin Time (PTT)
  • Have had a normal Pap smear within the past 12 months
  • Are practicing non-hormonal or stable hormonal contraception
  • If the woman is not currently taking any hormonal contraceptives, has been off all hormonal contraceptives for a minimum of three months prior to study enrollment, and agrees to continue without change in regimen through the 12 months of follow-up OR
  • If the woman is currently taking hormonal contraceptives, has taken hormonal contraceptives for a minimum of three months prior to study enrollment, and agrees to continue without change in regimen through 12 months of follow up.**

**Note: Hormonal contraceptive use must be terminated 30 days prior to treatment but should be resumed post-operatively within 60 days post treatment as instructed by the Investigator.

  • Are willing and able to comply with all study tests, procedures, and assessment tools
  • Are willing and able to return for all required follow up visits following study enrollment
  • Must pass a pre-operative health exam (ASA I-III)
  • Are capable of providing informed consent

Exclusion Criteria

  • Have contraindications for laparoscopic surgery and/or general anesthesia. (Contraindications include anemia, defined as a hemoglobin level under 10 or hematocrit level less than 30.)
  • Have had prior pelvic surgery (with the exception of C-section, tubal ligation, or diagnostic laparoscopy), or are known to have significant intra-abdominal adhesions (defined as adhesions that would require extensive dissection to mobilize and view all surfaces of the uterus)
  • Have previously undergone endometrial ablation, uterine artery embolization, or uterine artery ligation, or any other uterine-preserving technique for reduction of menstrual bleeding (with the exception of hysteroscopic myomectomy > 1 year ago)
  • Patients requiring elective concomitant procedures
  • Have contraindications for magnetic resonance imaging (MRI)
  • Desire current or future childbearing
  • Are pregnant or lactating
  • Have taken any Gonadotropin-releasing hormone (GnRh) agonist within three months prior to the screening procedures
  • Have an implanted intrauterine or fallopian tube device for contraception that cannot or will not be removed one month prior to treatment
  • Have dysfunctional uterine bleeding or bleeding between periods
  • Have chronic pelvic pain not due to uterine fibroids
  • Have known or suspected endometriosis
  • Have known or suspected adenomyosis based on Ultrasound or MRI findings
  • Have active or history of pelvic inflammatory disease
  • Have a history of or evidence of gynecologic malignancy or pre-malignancy within the past five years
  • Have had pelvic radiation
  • Have a non-uterine pelvic mass
  • Have a cervical myoma
  • Have one or more pedunculated subserosal fibroids or "type zero" (completely intracavitary) submucous fibroids
  • Are peri-menopausal (defined as women 40 years of age or older with Follicular Stimulating Hormone level of ≥ 25 International Units (IU) or menopausal
  • Are unable to give inf
