NovaSure Impedance Controlled Endometrial Ablation System
The NovaSure Impedance Controlled Endometrial Ablation System (Model 09) is a Thermal Radio-Frequency Device that is inserted transcervically into the uterine cavity and, using the RF Controller, delivers radio-frequency energy to treat the interior surface of the uterine cavity. The actual radio-frequency treatment requires an average of approximately 90 seconds. Neither Concomitant Hysteroscopic Visualization nor Endometrial Pre-Treatment is required.
During the Ablation process, radio-frequency energy Dessicates and Coagulates the Endometrium and the underlying, superficial Myometrium. As tissue destruction progresses, electrical impedance of the tissue increases. The procedure terminates when impedance at the tissue-electrode interface reaches 50 ohms or when the total treatment time reaches two minutes, whichever comes first.
