The Novasure endometrial ablation system consists of a single-use device and a radiofrequency controller. It is a three-dimensional, triangular-shaped bipolar ablation device. The generator functions at 500 kHz and has a power cut-off limit set at a tissue impedance of 50 Ohms. The self-terminating procedure is based on tissue impedance or time. A cavity assessment system works to detect perforations in the uterine cavity. No pretreatment is necessary. Randomized controlled trials have shown that the Novasure system has an amenorrhoea rate of 44–56% at 1-year follow-up, and the 5-year results of a randomized trial will be published shortly. Prospective observational studies show even higher amenorrhoea rates of up to 58–75% up to 5-year follow-up. Hysterectomy rates in the prospective trial were very low (4%). In summary, the Novasure endometrial ablation system is an effective second-generation ablation technique, resulting in a high percentage of amenorrhoea.
