The Minerva Endometrial Ablation System is intended to ablate the endometrial lining of the uterus in pre-menopausal women with menorrhagia (excessive bleeding) due to benign causes for whom childbearing is complete.
The Minerva Endometrial Ablation System utilizes electrical current to ionize argon gas that is fully contained and circulated within a sealed silicone membrane. When this stretchable silicone membrane is deployed, it conforms to the uterus. When the system is energized, the argon gas is ionized, turning it in to plasma. The argon plasma heats the silicone membrane, and this thermal heat, is conducted to the tissue in contact with the membrane.During the ablation cycle, the Minerva system does not proactively evacuate the liquid contents from the uterine cavity. These liquids remain in the uterine cavity, are heated by the silicone membrane, and the retained heated liquids are used to ablate the endometrial tissue, along with the tissue penetrating bipolar RF current in an impedance-mediated resistive heating environment.
The combination of three mechanisms of ablation creates a uniform and reproducible ablation of the endometrium:
