NovaSure endometrial ablation

Abnormal uterine bleeding (AUB) can dramatically affect a woman's comfort, confidence and quality of life. To help women with AUB reclaim their lives, Hologic offers NovaSure endometrial ablation, a safe, simple solution used by more than 2.5 million women. Since it was launched in 2001, the NovaSure system has continued to evolve.  In February 2017, Hologic introduced the NovaSure ADVANCED device, further refining global endometrial ablation (GEA) to help physicians manage their patients' procedural experience.

The NovaSure system enables you to provide comfortable customized ablation procedures right in your office or in the operating room. Using radiofrequency impedance-based technology, the NovaSure system delivers the fastest treatment time of any system of its kind, with no hormonal pretreatment required. And, it can be performed any time during a woman's cycle.


NovaSure endometrial ablation is a one-time, customized treatment for women who suffer with AUB. This 5-minute procedure can be performed in the office or operating room, and over 90% of women return to normal, light or no periods at all. The NovaSure procedure is a safe and effective way to improve the lives of patients with AUB.

Prevalence, Characteristics and Causes

AUB is more common than most women think. It’s estimated that AUB affects 1 out of every 5 women — that’s about 10 million women!1

AUB is characterized as menstrual bleeding that is unrelated to normal menstruation. A normal period cycle is typically about 28-35 days with bleeding lasting 5-7 days.2 Women with AUB experience much heavier bleeding for longer periods of time than what is considered a normal menstrual cycle. One of the most common symptoms of AUB is heavy menstrual bleeding that lasts for more than 7 days, which may require double protection or affect quality of life.AUB is also characterized by bleeding in between periods, after sex, for more than 35 days or less than 21, and spotting during the menstrual cycle.4



Our Technology

The unique, radiofrequency impedance-based technology available with the Hologic NovaSure system customizes patient results, delivering:

  • Quick and controlled bipolar radiofrequency (RF) energy —  a proven ablation modality in many surgical specialties.
  • A customized ablation when the scientific endpoint of 50 ohms of impedance or 2 minutes is reached.
  • Individual cavity measurements for each patient, enabling you to tailor the treatment to the specific patient.
  • The only system with a proprietary proactive safety check prior to the procedure to assess cavity integrity; insufflating the cavity using CO2, the system can detect pressure leaks to confirm uterine cavity integrity. 
  • A unique moisture transport system, which ensures tissue contact with the array and removes steam, blood and other byproducts; removal of steam during the procedure is essential to maintaining a controlled ablation.
  • Treatment regardless of a patient's cycle and without any pretreatment required.

Innovative features of NovaSure endometrial ablation system include:

  • Bipolar RF energy.
  • Proactive cavity integrity assessment.
  • Proprietary moisture transport system.
  • Scientific endpoint.
  • RFC10 controller — enhanced with a touchscreen interface and  intuitive graphics for improved workflow. 
  • Hologic's next generation NovaSure® ADVANCED endometrial ablation system also offers:
    • Rounded Tips- for easier insertion 
    • Smaller Diameter- for approximately 6 mm of cervical dilation
    • Improved Cervical Seal- for an increased sealing surface9

Important Safety Information:

NovaSure is for premenopausal women with heavy periods due to benign causes who are finished childbearing. Pregnancy following NovaSure can be dangerous. NovaSure is not for those who have or suspect uterine cancer, have an active genital, urinary or pelvic infection or an IUD. NovaSure is not a sterilization procedure. Rare but serious risks include but are not limited to thermal injury, perforation and infection. Temporary side effects may include cramping, nausea, vomiting discharge and spotting.
