NovaSure Endometrial Ablation

Proven Results.

NovaSure endometrial ablation is a quick, safe and simple procedure to lighten or stop periods without the side effects of hormones or the risks of hysterectomy.  

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 million women since it was Health Canada and FDA-approved in 2001.



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 include:

  • Bipolar RF energy.
  • Proactive cavity integrity assessment.
  • Proprietary moisture transport system.
  • Scientific endpoint.

Hologic's next generation NovaSure endometrial ablation system also offers:

  • New NovaSure 6mm — a device with a nominal 6mm tip diameter, potentially further reducing procedure time and discomfort. 
  • DuraSheath technology maintains quality and integrity of the device during ablation. 
  • Soft, elongated cervical seal creates an increased sealing surface within the cervical canal. 
  • Blue front handle aids in proper insertion technique.
  • RFC10 controller — enhanced with a touchscreen interface and  intuitive graphics for improved workflow. 
  • SureSound uterine cavity measuring device — improved functionality for better measuring accuracy.

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.
